Accuracy day has arrived. And this is going to be a report that’s different than the ones I normally write because I decided to do things differently with the Benjamin Trail NP pistol. First of all, there’s some interest in the gun. Readers have said they’re watching the reports because this gun seems to deliver a lot of performance for a very reasonable price.
Next, I’ve read some owner reviews that talk about the gun hitting low. I wanted to test that for you. Owners also say the pistol shoots to two different impact points, depending on whether or not the cocking aid is attached.
Finally, I received a call from Crosman’s head engineer, Ed Schultz, who noticed I was testing the pistol now. Ed confirmed that the pistol does indeed shoot to two different points of impact, depending on whether or not the cocking aid is attached. He was also intrigued by how much I seem to like the air pistol, so we chatted about that for awhile.
How this test will be different
I decided to “play” with this pistol today instead of plowing through a formatted test with X number of pellet types. What that means is that I decided to let the pistol lead me through the test, and to look at those things that were interesting — even if they didn’t conform to my normal test format. I think the test went well, but it lead me in directions I might never have taken otherwise.
It shoots low
The first pellet up was the RWS Hobby. The first shot wasn’t even on the paper, so I elevated the rear sight as high as it would go, then I held up the front post above the rear notch in a style that was popularized by Elmer Keith. That got me on paper, and I put 10 shots through the gun. They landed in a group that measured 1.155 inches between centers. This turned out to be the best group of the test, and I think it shows the accuracy potential of the pistol quite well. You see, I was estimating how much front post to hold up above the rear notch while I shot this group, so my aim point was only an estimate.
When Elmer Keith wanted to shoot handguns farther than their sights would allow, he used this holdover sight picture. Keith inlaid gold lines on his front sights, but I am simply estimating the height from shot to shot.
Even when I held over a lot, the pellets landed below the aim point. So, I used another trick by drawing a secondary aim point above the main bull and using the holdover sight picture on it (at 6 o’clock). My sight picture now looked like the drawing above.
Next, I tried the lead-free Crosman Powershot Penetrators. Using the higher aim point, I put 10 of them into a group that measured 2.527 inches between centers. Obviously, they’re not right for this pistol.
Different impact point?
I told you I was playing with the pistol, so next I tried an experiment to see the difference in point of impact when the cocking aid was left on the gun or removed during firing. And there was a difference! For this test, I used JSB Exact RS domes.
I used the same high aim point, and the pellets landed about 2 inches lower when the cocking aid was left on the barrel during firing. I’ll show both groups on the same target, so you can see what that looks like.
The group fired with the cocking aid installed was slightly tighter than the one with it removed. The one with the cocking aid measures 1.369 inches between centers, while the other group measures 1.636 inches.
I reported that the cocking effort is low for this pistol. Well, that’s fortunate; because when I shot it without the cocking aid, I also cocked it that way. The effort required with the aid installed still measures 25 lbs., and with the aid removed it increases to 35 lbs.
This time, I shot the pistol indoors, and I still must say that it’s very quiet for the power. I think some new owners may have had a few detonations when their guns were new and thought their pistol was going to always be that loud, but I doubt that many will fault it for the sound after it calms down.
The trigger-pull isn’t so much heavy as it is long. It does take some concentration and even discipline to shoot the pistol at its best. But there’s no creep in the second stage.
Crosman Premier heavies and JSB Exact 10.34-grain heavies
I had thought that heavier pellets might do best, so I tried both Crosman Premier heavies and JSB Exact heavies. Since I was just playing with the gun instead of conducting a formatted test, I decided that if either pellet didn’t show any promise by 5 shots, I wouldn’t complete the group. Well, neither one did, so I ended each group at just 5 shots. Both would have been over 2 inches for 10 shots.
Crosman Premier lites
The last pellet I tested was the 7.9-grain Crosman Premier lite, figuring that if the heavy didn’t group, the lite might. And that was correct. The lites gave me a 1.775-inch group, which doesn’t sound good. But 9 of those pellets are in 1.314 inches, which is a lot better.
What’s the verdict?
The verdict is — it’s too soon to tell. I still have some things to test with this pistol. For starters, the sights that are on the gun are so problematic that I want to try it with a good quality dot sight and see what I can do. If I can adjust the sight so I’m able to aim at what I’m hitting, and if I use the 3 pellets that worked well in this test — RWS Hobbys, JSB Exact RS and Crosman Premier lites — then we might just see a more accurate gun.
I also want to test pellets that are seated deep in the breech to see if there’s any difference. There are the two lead-free pellets that Crosman sent, but I didn’t get around to testing this time. I’d also like to run a velocity test after all of that because, by then, I think the gun should be broken in.
More than ever, I think Crosman should build this gun as a carbine, using exactly what they have here but with an extended barrel shroud and a rifle stock. As easy as it is to cock as a pistol, I can see it losing another 10 lbs. of effort as a carbine. What a wonderful little plinker it would make!

Today, blog reader Paul Hudson shares his Theoben Crusader rifle with us. The Crusader is not as well-known in the U.S. as some other Theoben models, so this will be an interesting report.
If you’d like to write a guest post for this blog, please email us.
With its walnut stock, the Theoben Crusader is a large, handsome airgun.
The Theoben Crusader is a high-power breakbarrel airgun, identical in size and performance to the Beeman R1. Its stablemate, the Theoben Eliminator, seems to get far more press since it’s one of the most powerful breakbarrel airguns available. That power comes with a high price — a cocking effort of 50+ lbs. — that most shooters are not willing to endure for very long. The Crusader, on the other hand, is far easier to cock and is a more practical airgun. Based on the used guns I’ve seen for sale, either the Crusader sales are much lower or people tend to keep them. Few are seen on the usual airgun sales sites or at airgun shows.
The Crusader is a high-quality spring-piston rifle.
Measuring a full four feet in length and weighing 8 lbs., 3 oz. unscoped, the Crusader is a large airgun. Mine is .177 caliber; but .20, .22, and .25 calibers are also available. The Lothar Walther barrel is 16 inches long, and a muzzlebrake is standard equipment (.22-caliber Crusaders have an Anschütz barrel). There are no baffles in the muzzlebrake. No open sights are supplied by the factory, making an optical sight a necessity. My rifle has a right-hand walnut stock, but an ambidextrous stock can be had from the factory as a no-cost option. The pressed checkering does give enough grip to be functional. A very good non-slip recoil pad keeps the rifle in place. No plastic parts are used on the rifle.
The metal work on the Crusader is first-rate, with a high polish that’s typical of many British airguns, and the wood-to-metal fit is excellent. Allen-head screws are used throughout the gun except for one screw that secures the triggerguard.
Behind that screw, a Schrader valve allows the owner to change the air pressure in the gas spring. Note the thumb rest in the stock.
A gas spring
Like all Theoben springers, the Crusader uses a gas spring, not a metal spring. Cocking is butter-smooth and requires 38 lbs. of effort. The piston includes a sliding weight that reduces piston bounce and felt recoil. A Schrader valve at the rear of the receiver allows the pressure in the gas spring assembly to be adjusted to vary the power of the gun. Upon firing there’s no spring twang or vibration, just a quick snap. The sound level is moderate. And, due to the size of the gun and careful tuning, the felt recoil is mild for the power level.
The lower bolt is pinched between the breech block and the locking wedge to prevent vertical barrel movement. Note the taper at the rear of the barrel to make pellets easier to seat.
The barrel pivot setup on the Crusader is a little unusual. Most breakbarrels use a breechblock that’s close to the width of the forks of the receiver. Wide, thin shims may also be present between the breechblock and the receiver forks. The pivot bolt is then tensioned to the point that the lateral barrel movement is constrained. The breechblock on the Crusader has much more side clearance. Belleville washers are used to control the lateral movement. Belleville washers are cone-shaped from the side and are actually considered to be springs. A second bolt behind the pivot bolt mates with a hook on the back of the breechblock. The locking wedge pulls the breechblock tightly against this bolt to control the vertical movement of the barrel. Like many classic Webley rifles, the Crusader takes a bit of a slap to open the barrel for cocking.
The unusually wide breechblock/fork clearance is visible from below the action. (The photo is overexposed, leading to the yellow stock color. This was necessary to bring out the detail within the cocking slot.)
The Evolution trigger of the Crusader and other models has been criticized by some; and given the price of the gun, that may be justified. No creep is felt in the first stage, but the second stage is not as crisp as a Rekord trigger. As the gun came from the factory, the second stage breaks cleanly at 1 lb., 13 oz. The safety blade resides in front of the trigger and automatically sets when the gun is cocked. It can also be manually reset. Overall, I would rate the Crusader trigger as very good, just not quite as good as a Rekord or TX200 unit but not a reason to avoid the gun.
The trigger blade is almost straight; the automatic safety resides in the front of the triggerguard and is pressed forward to fire.
Velocities with the Crusader are similar to what’s found in a Beeman R1, and some lighter pellets in a .177-caliber rifle will go supersonic and ruin the accuracy. I tried a couple H&N Field Target Trophy Green pellets, but they traveled almost 1200 feet per second and missed the bullet trap at 25 yards. Extreme spreads with most pellets were under 20 feet per second, and a few varied by less than 10…very good for a springer.
These are the velocities the Crusader can deliver with the selected pellets.
Many pellets gave 5-shot groups around an inch in size at 25 yards. Several gave very good accuracy, including a few that surprised me. To get the best accuracy shooting from the bench, I had to hold the airgun loosely with my right hand and keep my left hand open. If I let my fingers touch the forearm, I had to make sure I didn’t squeeze the gun at all or the groups would open up. In other words, use the classic artillery hold. You cannot grip this airgun tightly and get good accuracy; it’ll take practice and proper technique to get the best results.
All groups were 5 shots at 25 yards, and the sights were not adjusted for the different pellets. It was interesting to see the difference in the points of impact. Predator Polymags and 8.4-grain JSB Exacts shot especially high in relation to the other pellets. Unfortunately, neither 7.9-grain Crosman Premier lites nor 10.5-grain Premiers heavies did much better than one-inch groups at 25 yards. While that’s not too bad, a number of pellets did far better.
Five H&N Baracuda Hunters made this 0.50-inch group.
Five Predator Polymag pellets made this 0.40-inch group. Good enough for hunting.
Gamo TS-10 surprised me with a 0.45-inch group; but their size seemed a bit inconsistent, and there were some flyers with this pellet.
Skenco Big Boys gave this nice 0.43-inch group. The group is almost twice as wide as tall.
The 13.4-grain JSB Monster also produced a 0.43-inch group.
The Crusader really liked the 8.4-grain JSB Exacts, as this round 0.24-inch group shows.
Best accuracy came from the Beeman Kodiak pellet. This group above is just 0.23 inches.
Adding it all up
Why buy a Crusader? After all, it costs just over $1000, and that price will keep many away. Compared to a Beeman R1, the size and power are identical. The R1 has a better trigger, but the Crusader has a better firing behavior due to the gas spring. The Crusader also has a far nicer stock, better metal finish and includes a factory muzzlebrake. Between my Crusader and my R1, the Crusader shoots more pellets accurately and will shoot slightly smaller groups, probably due to the fine Lothar Walther barrel. Unfortunately, the Crusader is more hold sensitive than my R1.
Both rifles should last a lifetime with proper care. It’s possible to upgrade an R1 with a new stock, a gas spring, muzzlebrake, etc., but you’ll end up spending more than the cost of the Crusader and still do not have the nice metal work. If you can afford it, the Crusader offers very good accuracy in a nicely finished package.
Theoben Production ceases
In October, 2012, Theoben Ltd. in England announced that they were entering liquidation (bankruptcy). It remains to be seen whether another company will take over production rights for Theoben springers.

I usually have a handle on the gun by the time Part 4 rolls around. But, today, I’m still stymied by the Tech Force M12 breakbarrel. I’ll tell you all I’ve done to make sure this rifle is on the beam; but when I tell you my results, I think you’ll see I’m not there yet.
I discovered in Part 3 that the M12 I’m testing is a big drooper. That means it shoots very low relative to where the scope is looking. For today’s test, I installed a B-Square adjustable scope mount that has a huge downward angle to bring the point of impact back up to the aim point. It worked well enough for the test, so I proceeded to shoot several different types of pellets — trying all kinds of hand holds and even resting the rifle directly on the sandbag.
Here’s a list of the pellets I tried: (10-shot groups with each)
Beeman Kodiak Hollowpoints
Crosman Premier 10.5-grain
Crosman Premier 7.9-grain
JSB Exact RS
JSB Exact 8.4-grain
JSB Exact 10.3-grain
Beeman Trophy (an obsolete domed pellet)
Eley Wasp (an obsolete domed pellet)
With most of these pellets, the rifle teased me with several pellets in the same hole — but a 10-shot group that was 1.5 inches and larger. A couple were all over the place and simply would not group at all. The Hobbys were probably the worst.
Only one pellet put 10 shots into 1.038 inches at 25 yards. Those were RWS Superdomes, and the hold was with my off hand back by the triggerguard, leaving the rifle very muzzle-heavy. The rifle was somewhat twitchy but not overly so.
The encouraging thing about this group is that I didn’t have to use a lot of technique to shoot it. I know it isn’t as tight as others I’ve shot at the same distance, and you’ll compare it to them, but I compared it to the other groups I was getting with this rifle. In that comparison, this was the best one and it was also relatively easy to shoot.
What all did I do?
For the record, here’s a list of all the things I tried to get the M12 to shoot.
Cleaned the barrel
Tightened the stock screws (they were tight)
Installed a drooper mount with a lot of down angle
Tightened the scope mount screws (and they were loose on the B-Square adjustable mount!)
Tried resting the forearm of the rifle:
On my open palm in front of the triggerguard
On my open palm under the cocking slot
Directly on the sandbag
Tried shaking the barrel to test the breech lockup (it is tight)
Tried extra relaxation with the artillery hold — which worked for a few shots, but never more than four
Tried attaching an extra weight to the barrel during each shot (with a large magnet)
So, where are we in this test?
I still think the M12 can shoot because there’s evidence of it wanting to stack its pellets. It might be that this is a rifle that needs more than a thousand shots to break in. I’ve owned a few of those. The Beeman C1 from Webley that I used to own was such a rifle. At first it was a royal beast; but as the shot count passed 2,000, the rifle began smoothing out and transforming into something very delightful to shoot. By 4,000 shots, the trigger was very nice and the gun had no vibration to speak of. It was this very rifle that caused me to give the artillery hold its name, and I wrote the first article I ever wrote about airguns for Dr. Beeman. He didn’t respond to my submission, so I saved it and eventually wrote it up in The Airgun Letter.
I wonder if this M12 needs that kind of break-in? That’s something I haven’t done in a good many years because it takes so much of my time. But it might be interesting to see if the rifle responds to a long-term break-in. I think I’ve certainly shoot 250-300 shots at this point, because I also tested the gun at 10 meters and one time at 25 yards (it wasn’t reported). Maybe I’ll rack up some more shots to see how that affects a longer-term break-in.

Today, we’ll learn an important lesson in spring-gun management. This report was supposed to happen yesterday, but the rifle wasn’t cooperating — and I had to spend an extra day testing it. I’ll explain what haoppened and tell you what I did to fix it. It was simple, and the results are astounding. But, I’m getting ahead of myself.
As you know, I elected to test the .177-caliber Tech Force M12 4-12×40AO air rifle combo. I chose the package that came without the illuminated reticle but with the best scope.
I mounted the scope with no difficulties. The two-piece rings went on the rails easily and the rifle’s end cap was used to block the rear ring from moving during shooting. I can tell you at this point that you have nothing to fear using the cap this way. The end cap holds the ring positively and doesn’t seem to move.
Trouble in paradise!
But at 25 yards, I found I had difficulty shooting a group that was reasonable. The best I managed to do was 10 shots in an inch and a half, but I also had some that went two inches. It was discouraging, to say the least. I sat back and examined the groups to see what could be learned.
And one thing popped out. Each group of 10 was actually two very tight groups of pellets. There was enough dispersion that at first they just looked like a large group; but since I’d seen every shot go through the target and I remembered them going from one side to the other, I was able to see that there were actually two separate groups. And you know what that means, don’t you?
Let’s look at this from a different perspective. Let’s say a new reader wrote a comment and complained about the lack of accuracy in his new rifle. We might have to go back and forth several times before he mentioned that there are really two smaller sub-groups in the one group he shoots. But that would be the key that triggers a response.
Many of you would advise this reader to remove the scope from his gun and shoot a group with open sights. That’s what I would do. Only in the case of this rifle, there are no open sights. What do you do then?
There is a “secret.” It really isn’t a secret; but from experience, I’ve found that only a few people know about it.
The secret is this: When you get multiple groups like this, the problem is usually caused by a floating erector tube inside the scope, assuming that all the mounting screws are tight. And in this case, I checked them and all were tight. The stock screws were also tight. So the erector tube is the suspect. The thing that sets it up to move like that is when the scope is adjusted up too high or too far to the right, so the erector tube spring (the spring that pushes against both adjustment knobs) has relaxed to the point that the tube can move. It’s a common fault when using a scope, and I’ve been seeing it more and more often with firearms, too.
What I would tell a new reader is to crank a LOT of down elevation (at least 60 clicks — more is better) into his scope and shoot a group. I don’t care that the pellet is now striking the target low. What I care about is the size and shape of the group. That’s exactly what I did. I cranked in 5 or 6 full rotations of down elevation into the scope.
Because the rifle was now shooting very low, I decided to test the rifle at 10 meters just to keep the shots on the paper. I’m not going to tell you the pellets that were tried at 25 yards because what follows explains why they were not tested fairly.
The first pellet I tried in this experiment was the 10.3-grain JSB Exact dome. Inside of 3 shots, I knew I’d found the problem and was fixing it. The 10-shot group I got is not that small for just 10 meters, but it was relatively easy to shoot, meaning that I did not have to use more than the usual amount of artillery hold technique.
Next, I tried Crosman Premier heavies, thinking that the rifle was going to lay them in no matter what it was fed. But not this time. When 4 shots gave me almost 1.5 inches, I stopped! Clearly, this 10.5-grain dome is not the pellet for the M12.
Then, I tried a pellet that has never worked in any test I’ve done. The Beeman Trophy pellets I have are so old that they come in the old-style Beeman tin. But, I thought, what the heck — this is just a test. Let’s see what they can do. And, of course, they were stunning. Ten made a group that measures 0.458 inches, but 8 of those 10 shots made a 0.253-inch group that’s very round and encouraging.
Not only did the Trophy pellet make a nice round group, it also required very little special shooting technique. The gun felt like it was in the zone with this pellet.
I have to say this 4-12×40AO Tech Force scope that came with the rifle is a pretty nice optic for being included in a combo package. It focuses clearly and seems bright enough for general use. Once I found the problem, this scope performed as well as any scope would under similar circumstances. If you plan to purchase an M12, I would recommend getting it the way you see here.
Where are we with the Tech Force M12?
Obviously, I haven’t finished the test of the M12. I still need to shoot the rifle at 25 yards to see how well it does. And I know the groups are going to be larger than what you see here. Before I do that, I need to mount this scope in a good drooper mount so I can get the gun shooting to the point of aim, again.
Today’s report is a valuable lesson in what to do when you’re having problems getting a scope to work. The diagnostic for this is when the rifle wants to shoot several groups that are each respectable; but when taken together, they’re too large. In the situation I’ve shown here, we didn’t know if the problem was the rifle, the scope or something else. By dialing in a lot of down elevation and sometimes some left elevation, we put tension on the erector tube springs, taking them out of the equation. If the gun then shoots well, as this M12 clearly did, then you know you have a droop problem that’s easy to solve.

We last looked at the .22-caliber Talon SS on June 13, when I told you that I had mistakenly shot the rifle with a standard air tank instead of a Micro-Meter tank in the previous test. I retested the rifle with an AirForce Micro-Meter air tank and the standard 12-inch barrel. Today, I want to finish the test with the optional 24-inch barrel.
You’ll recall in Part 8 that I shot the rifle 380 times on a single fill of the Micro-Meter tank. Today, we’ll see what difference, if any, we get from the 24-inch barrel. The only pellet used in this test was the .22-caliber Crosman Premier pellet.
Let’s begin — shots 1 to 10
The tank is filled to 3,000 psi and shooting starts. The power wheel is set as low as it will go. The first three shots go 429, 536 and 667 f.p.s., respectively. Shot four goes 726 f.p.s. and the rifle is stable from that point on. The first three shots were needed to wake up the valve. Discounting the first three shots, the string averaged 727 f.p.s. and ranged from 725 to 732 f.p.s., a spread of 7 f.p.s. The average energy was 16.79 foot-pounds; and yes, I’m aware that a Micro-Meter tank isn’t supposed to be that powerful. But we’re seeing the effect of doubling the barrel length in a precharged gun, and it’s dramatic!
Because of the large number of shots I expect to get from the tank, I then shot 30 shots without a pellet. I’ll call these blank shots.
Shots 41 to 50
This string averaged 715 f.p.s. and ranged from 711 to 718 f.p.s, so another 7 foot-second spread. The average energy was 16.24 foot-pounds. Then another 30 blanks were fired.
Shots 81 to 90
I shot this string on the highest power setting the gun has — just to see if there was any difference. There wasn’t. The average was 705 f.p.s. and the range went from 702 to 709 f.p.s. Another 7 foot-second spread. The energy was 15.79 foot-pounds. Then another 30 blanks were fired.
Shots 121 to 130
The gun was set back to the lowest power setting and remained there for the rest of this test. The average was 675 f.p.s., and the range went from 668 to 679 f.p.s. the spread was 11 f.p.s. The average energy was 14.47 foot-pounds. Then 30 more blanks were fired.
Shots 161 to 170
The average was 658 f.p.s., and the string ranged from 654 to 662 f.p.s. — a spread of 8 f.p.s. The average energy was 14.17 foot-pounds. Then 30 more blanks were fired.
Shots 201 to 210
The average was 641 f.p.s., and the range was 637 to 653 f.p.s. This string had a 16 foot-second spread. The average energy was 13.05 foot-pounds. Following this, 30 more shots without pellets were fired.
Shots 241 to 250
The average for this string was 618 f.p.s., and the string ranged from 613 to 621 f.p.s. So, a spread of 8 f.p.s. The average energy was 12.13 foot-pounds. Following this, 30 more blanks were fired.
Shots 281 to 290
This string averaged 594 f.p.s. and ranged from 581 to 601. So a 20 f.p.s. spread. The average energy was 11.21 foot-pounds. Then 30 more blank shots were fired.
Shots 321 to 330
The average was 561 and ranged from 553 to 568, and the spread was 15 f.p.s. The average energy was 10 foot-pounds. After this, 30 more shots were fired without pellets.
Shots 361 to 370
The average was 539 f.p.s., and the string ranged from 534 to 545. A spread of 12 f.p.s. was observed. The average energy was 9.23 foot-pounds. Another 30 blanks were fired.
Shots 400 to 410
Now we’re in uncharted territory. The gun is giving me over 400 good shots on a single fill. Clearly, the 24-inch barrel is a real boon to the performance of the MM tank. This string averaged 519 f.p.s. and ranged from 514 to 527 f.p.s. A spread of 13 f.p.s. The average energy was 8.56 foot-pounds. After this, 30 more blanks were fired.
Shots 441 to 450
The average was 497 f.p.s. and the string ranged from 489 to 504 f.p.s., for a total spread of 15 f.p.s. The average energy was 7.85 foot-pounds.
I could have continued to shoot the gun for many more shots, but I stopped at this point for a reason. After 450 shots have been fired, the Talon SS is still launching pellets slightly faster than my Diana model 27 breakbarrel. If that’s enough power for me, then this gun certainly gives all that and more. And I can’t think of another time when I shot 450 shots, unless it was for a test like this one.
The 24-inch barrel added significant performance
We all know that barrel length is important to a PCP, and this test makes that very clear. The 12-inch barrel gave 380 shots that ended up in the high 300 f.p.s. range. We’re still 200 f.p.s. faster than that after 450 shots have been fired! I think that establishes the Micro-Meter air tank as the champion of PCPs with the 24-inch barrel is installed.
In this series, we’ve looked at the Talon SS as it comes from the factory and with various modifications. The one we haven’t tried yet is the CO2 adapter, so that’s next. I’ll leave the 24-inch barrel installed since that’s the way I shoot the rifle all the time now, but I’ll test both velocity and accuracy with CO2 for you.

Kevin is responsible for this special Part 4 report on the Gamo Rocket IGT .177 breakbarrel. He pointed out that I didn’t give the rifle enough of a chance to excel in the accuracy test, and several of you agreed. Even Edith chimed in when she read Kevin’s comment. In light of the leniency I have shown the recently tested Hatsan springers, this is certainly true. I won’t change my normal way of reviewing airguns, but in this instance I can see that it makes good sense to try other pellets in this rifle.
It takes a long time to shoot a 10-shot group, so I resolved to shoot just 5 shots per pellet and see where that left me. If the five were reasonably close, I would complete the group with the other 5 shots.
First up was Kevin’s favorite, and a pellet I’ve found to be accurate in a variety of air rifles — the JSB Exact RS dome, which weighs 7.33 grains. I was prepared to be surprised by the accuracy, but RS domes delivered 5 shots into 1.29 inches at 25 yards. So I stopped shooting them. I remembered that the lighter pellets did worse in this rifle in the last test, so next I tried the heavyweight Beeman Kodiak pellet.
The first Kodiak pellet went way to the right of the aim point, then the next one about an inch to the left of that. After that, the pellets went to the same place until shot 6, when the pellet went back to the right. Some time in the final 4 shots, 2 pellets went to the right and low. How do I interpret this?
Kodiaks gave me this group. Six of the 10 shots are nicely grouped, but 4 others open the group considerably. This 10-shot group measures 1.257 inches between centers. The smaller group of 6 measures 0.635 inches.
This group made me wonder if I was being consistent enough with the Rocket IGT. Did I “season” the bore with enough pellets before shooting the group? I actually didn’t season it at all, but the fact that the last Kodiaks are as wide of the large group as the first one makes me think seasoning isn’t important here.
Was I holding the gun as carefully as I should be? That was a real concern. I hadn’t put a scope level on the gun, but was I completely relaxing and then shifting the crosshairs back to the target like I should?
Bottom line, I wanted to see another group of Kodiaks. That would perhaps tell me what I needed to know.
Ten more Kodiaks went into this group that measures 1.906 inches between centers. Eight of those pellets went into 0.784 inches — a group size that I think represents the true accuracy potential of the Rocket IGT.
The second group is very revealing. I tried just as hard to shoot well as I had with all the groups before, and there were no called fliers, but you can see from this group that some pellets didn’t want to play along. That tells me I’m probably not doing something consistently, and it’s affecting the results.
I tried one final group of 10 Crosman Premier heavies, just to see what another heavy pellet might do. This time, the 10-shot group was better than both groups of Kodiaks; but at 0.984 inches, it wasn’t as good as I’d hoped. The openness of this group makes me think that this is perhaps not the pellet for the Rocket IGT. But I’m not sure of that, either.
I’m going to give the Rocket IGT a fifth test, and this time I’m going to do everything I can to make it shoot well. I’m going to mount a more powerful scope, sort the pellets by weight, mount and use a scope level, and spend the time I need to shoot the finest groups possible.
You may not realize it, but it takes a LOT of time to shoot the absolute best you can. It takes me about 5 minutes per shot when I’m really working the artillery hold. I want to do this for this rifle because, in this test, I see the potential trying to peek through. Normally, the shooting I already did would be enough to make a decision.
If you think what I’m about to do is overkill, consider this. I shoot hundreds of different air rifles every year and never have the chance to get familiar with any of them. An owner who has just one rifle can, over time, become so familiar with that rifle that he can shoot like I am about to, but do it in far less time. But if I do take the time to settle in for each shot and if I do remove all of the accuracy-destroying variables, we will finally see what this rifle can really do.
Don’t think that I’m going to do this for every airgun test from now on. I’m doing it this time because Kevin and the other readers were right. The Rocket IGT needed more of a chance to shine; and when it got that, it showed the glimmer of a rifle that wants to shoot.
