Mac tests a steel IZH 61 with metal clips: Part 2

Photos and report by Earl “Mac” McDonald
This is the final report about Mac’s vintage steel-breech IZH 61. We are only doing two reports — partly because the rifle performs just like the one that’s being sold today, but mostly because Mac sold this rifle at the Roanoke airgun show this past weekend. He also bought one just like it that was like new in the box because he got a super price at the same show. That one will be given to some fortunate youngster, as part of Mac’s “Arm the Children” program!
Today, we’ll look at the accuracy Mac got from his rifle. Then you can compare it to what I was able to do with the IZH 60 I recently tested for you.
Trigger
As I reported in Part 1, this vintage rifle has a truly adjustable two-stage trigger, instead of just being able to reposition the trigger blade like on the current gun. Mac had it set to release at 27 oz., and he says it was crisp.
Someone wanted me to post a photo of the entire vintage rifle, but there isn’t that much difference between it and the current one. I didn’t think it was worth showing. Yes, if you’re a fanatic collector, there are some small differences; but I spent the weekend with the vintage gun before it sold, and it’s pretty much the same as what they sell now except for having a steel breech and metal clips.
Metal clips
On the subject of the metal clips, Mac says he has had some plastic clips that got worn to the point that they would no longer stay in the gun as they should. They’re supposed to advance one pellet each time the sidelever is pulled out to cock the rifle, but he said some of his would shoot out the side of the rifle because they’re under spring tension.
Sights
I showed the sights on this rifle in Part 1, but Mac tried both the peep sight that comes with the rifle and also a Tasco Pro Point dot sight with a 4 MOA dot. At the 10 meter distance he shot, the dot covered about 0.35 inches He e got equal accuracy with both types of sights, but all the groups seen in this report were shot with the Tasco.
He rested the forearm of the rifle on the palm of his hand and shot off a bag rest at 10 meters. We wanted to keep the results equivalent with those I recently got with the new rifle. And he also shot at 10-meter rifle targets, which is why he elected to use the dot sight. The hole in the factory peep sight is so large that there’s a loss of precision when using the smaller 10-meter rifle bulls. They get lost in the hole (meaning you can’t tell when they’re exactly centered). He could have used pistol targets that have a much larger bull, but he wanted his test to look just like mine.
Mac shot 5-shots groups instead of 10-shot groups. Things got confused in our talks, so we didn’t shoot the same number of shots per target. Still, I think you will see some interesting things as we go.
JSB 8.4-grain Exacts
The first pellet tested was the JSB Exact that weighs 8.4 grains. Five shots at 10 meters produced a group measuring 0.95 inches between centers. That’s pretty big for just 10 meters!

Five JSB Exact 8.4-grain domes at 10 meters made this 0.95-inch group. One pellet looks like it went through the paper sideways!
There are some indications of tumbling with the JSB, so it’s possible the rifle wasn’t stabilizing it. That would account for the large group.
RWS Hobbys
Next he tried RWS Hobby pellets. These are often among the most accurate in a low-powered rifle, but not this time. Five Hobbys made a 0.90-inch group.

The only nice thing I can say about the Hobbys is they did cut larger holes. They’re obviously not the right pellet for this rifle.
H&N Finale Match
Next up were H&N Finale Match Pistol pellets. Five of them made a group that measured 0.80-inches, but notice that one is apart from the other four. If there was something wrong with that pellet, it could explain why it’s apart. This might be the right pellet for the rifle, and it’s a good example of why one 10-shot group tells you more about accuracy potential than three 5-shot groups.

Five H&N Finale Match Target Pistol pellets made a group measuring 0.80 inches.
Eley Wasps
The next pellet Mac tried was one you can’t buy anymore. The Eley Wasp has left the stage, at least in the version Mac was shooting. It was an oversized pellet that sometimes cured accuracy problems for rifles with larger bores. In this rifle, 5 shots made a group that measures 0.70 inches. You’ll also notice that there don’t seem to be any signs of tumbling like there were with the JSBs.

Five Eley Wasp domes made a group measuring 0.70-inches. This group also has a single stray pellet, which means it might also have more potential than seen here.
RWS R10 Pistol pellet
The last pellet Mac shot was the RWS R10 Pistol pellet. These grouped best, with 5 of them making a 0.50-inch group. While that looks good in comparison with the other groups, it doesn’t begin to equal the groups I got with the new IZH 61 shooting 10 shot groups! That means is we have to revise our thinking about the old steel-breech/metal clip guns, don’t you think?

Five RWS R10 Pistol pellets made a half-inch group at 10 meters. It’s good only in comparison with the other groups, but doesn’t begin to equal the groups from the new rifle.
Our conclusions
Mac and I discussed these results at length, and we believe that the steel breech IZH 60/61 has perhaps become more accurate through the long lens of memory. Just as a walk to school was always 10 miles uphill in both directions when we were young, so it’s possible that these rifles were as variable back then as the new ones are now. From the results, we have to say that it looks like the current version of the gun is at least as accurate as the old one, if not more so.
We think that there were probably some very accurate rifles with steel breeches, and then the rest — which our test rifle seems to be — were only good plinkers. I know this test was hardly exhaustive, nor was it entirely without bias. Even so, I think we must admit that the new rifle beat the old one in this case.

Crosman MAR177 test report: Part 6

Part 5

Crosman’s new MAR177 upper is big news!
Today’s test is shooting the Crosman MAR177 at 25 yards, both with and without the magazine. We’ll also shoot it with the best wadcutter target pellets and the best domed pellets to see what differences there are.
Rather than shoot the rifle myself, I let Mac shoot it this time. He is the better rifle shot between us, and I just wanted to see what the rifle would be like in his hands. He shot it off a bag rest at 25 yards indoors. Ten pellets were shot from the magazine, then another 10 of the same pellet were shot using the single-shot tray. Mac tested both domed and wadcutter pellets, so we get to compare the relative accuracy of both today. And the results did not turn out as I expected.
Magazine
I’d noted in an earlier report that the particular 10-shot magazine I’ve been using has two chambers with tight entrances. Mac found the same thing without being prompted by me. I had him use the same magazine as I did so I could compare his results with all other variables remaining the same.
You’ll recall that I mentioned not liking magazine guns because of how they handle the pellets. So, today was also a test between the magazine and loading each pellet as you shoot. I’m not saying that all pellets have feeding problems, but that some magazines may have a problem. But when you load each pellet singly, you have less chance of damaging the pellet.
Single-load tray
That said, the MAR177 has a gap at the front of the single-load tray that can catch the nose of certain pellets and make it very difficult to load. The H&N Field Target pellets that were the most accurate in an earlier test had this problem and had to be exchanged for a different domed pellet. The H&Ns have a semi-wadcutter rim around the head that just catches in the gap on the tray and causes the pellets to flip up and possibly get damaged on loading. I substituted 7.3-grain Air Arms Falcon pellets that fed perfectly through the tray.
On to the shooting
Let’s get right to today’s test. First, Mac tested the domed pellets at 25 yards.

Through the 10-shot magazine, 10 Falcon pellets made this 0.667-inch group at 25 yards. This is very good!

When the single-shot tray was used, 10 Falcon pellets made this 0.429-inch group at 25 yards. This is clearly better than the group made using magazine-fed pellets.
Mac tried the H&N Field Target pellets first, and they were very accurate, but a couple of them refused to feed through the magazine. But the Falcon pellets fed flawlessly, so we changed the test to use them as the domed pellet of choice. Once again, I want to say that in another magazine this pellet might have fed better, but this is a quirk you get with mags that you don’t get when loading singly.
Clearly the single-loaded pellets are more accurate than those loaded by the magazine. That may not hold from magazine to magazine; but for this one mag, you’re better off loading the pellets one at a time. Let’s see how the rifle does with wadcutters at 25 yards.

Using the magazine, 10 RWS R10 7.7-grain pellets (an obsolete weight for the R10) grouped in 0.484 inches at 25 yards. That’s great performance.

When each pellet was loaded singly, the R10s grouped 10 in 0.402 inches. This was the best group of the test!
The trend continued with the wadcutter pellets. The R10s grouped even tighter than the Falcons at 25 yards, and those that were loaded singly did much better than those that fed through the magazine.
What have we learned?
First, we’ve learned that some magazines do influence the accuracy of the gun with all ammunition — or at least with the pellet types used in this test. A different magazine might well give different results, but one thing it will never do is outshoot loading the pellets by hand, one at a time. As a 10-meter shooter, I knew this going into the test. But it was nice that we were able to demonstrate it so clearly.
Next, we see that wadcutters were more accurate than the domes in this test. Even though both pellets were very accurate, the wadcutters had the edge. That was the part that surprised me. I’d expected the domes to take over at 25 yards.
The bottom line
The Crosman MAR177 is a valuable addition to an AR and a wonderful target rifle in its own right. It was held back in this test by the use of an AR National Match trigger, which is by no means as good as a target trigger on an air rifle. Even so, we see accuracy that any 10-meter precision rifle would be proud of.
I think Crosman has made a winning rifle in the MAR177. And when they bring out more powerful versions of it in the future, it’ll be all the greater justification for owning an AR! My thanks to Crosman for the loan of this MAR177 for both this test and for the feature article I am writing for Shotgun News!
