Now, let’s shoot the Gamo DynaMax PCP! I will say that this session went a lot different than the first time I shot the rifle. Then, I had the Gamo scope that came with the rifle mounted on the DynaMax, and the best 10-shot groups I could get at 50 yards were 1.5 inches across. That was because the scope has a large central dot that obscures a one-inch circle on the target paper, making it impossible to aim precisely.
The magazine was also feeding erratically at that time, so there were lots of jams and stoppages.
During the test I’m now doing for you, the magazine problems seem to have sorted themselves out and the mag now works flawlessly. I mounted a different 4-16x scope on the rifle, this one having thin crosshairs that enabled me to see things as small as 1/8″ at 50 yards. So, aiming was no longer a problem.
The day was perfect. Not a single breath of air moved, so shooting outdoors was like shooting inside.
H&N Baracuda
Sight-in took all of five shots, because the rifle was on target through a happy coincidence. The first five shots with H&N Baracudas after that looked very promising.
That was followed by a 10-shot group of Baracudas that measured 0.946 between the two widest centers. That’s very acceptable accuracy at 50 yards. It was also the largest group of 10 Baracudas I shot.
From this point on, I didn’t adjust the scope, so the other pellets will appear to move around the target a little, because they all shoot to a different aim point.
Crosman Premier 10.5-grain pellets
Crosman Premier 10.5-grain pellets gave the tightest group of the day. Ten went into a group measuring 0.541″ center-to-center. That’s on par with a custom-tuned Ruger 10-22 rifle shooting the best ammo. Please don’t confused the 10-shot groups with the 5-shot groups, which will be smaller and also less representative of the rifle’s true accuracy.
Air Arms 8.4-grain domes
Air Arms domes were not as good in the DynaMax. Ten of them went into a group measuring 1.192″ across the centers at 50 yards. They’re probably going way too fast for accuracy.
A final group of Baracudas
I was filling the DynaMax from a pump, plus I had other guns to test, so these 10-shot groups were taking time. However, I did shoot a final group of 10 Baracudas, just to see where things stood.

Adrian,
I answered this message in Part 2, where you also posted it. Here is what I said there:
Adimia,
I’m not aware of a recall on the Dynamax. But the specifications for each country are different, so what works in one may not work in another. What I’m saying is that a recall in one country may not affect the rifles sold in another country.
Also, what they call safety issues may not be safety issues but legal issues. They may just use safety as a cover for recalling a product they don’t want in the possession of the public. I don’t know the facts, so all of this is just conjecture, but I suppose you will do the right thing.

thisgun has issues.
Gamo service has not beenn helpful..but act like you are bothering them.
BSA maybe,,,, but same BS customer service….Gamo is making quite a rep.
cphp gave me the best group..heavies
of .708 over 12 shots @50 sweet but QC suffers
boycott Gamo
they suck and untill they know the customer is ALWAYS right attitude.
don’t buy any of their new stuff.
Ga at one time used to be a name you can trust.
call the CS line and see th attitude the gals hae from the first esecond on.
GAmo are you ereading this…You are trash.
BB i have over 10 springer that can match tha accuracy.
this gun is an abomiation……the Pneuma is 2/3 the cost and is far more accurate.
Fedo CAmo,
You have over ten springers that can shoot half-inch 10-shot groups at 50 yards? That is incredible!
You’re a lucky man to own such accurate spring-piston air rifles.

Thanks for your review, it helped me make the decision to buy it. I will confirm that barracuda’s and Kodiak are the best in it. This is the most accurate gun that i have ever shot period, even better than my Remington 7400 30-06. I was able to get 1.5″ groups at 100 yards with a ransom rest when i had no wind. The only thing i noticed is that some weird pellets like the high velocity plastic ones wont feed in the gun, but i don’t care, because they aren’t accurate anyway because no airgun has a high enough twist rate for them. Overall a beautiful good gun.
Trevor,
I’m glad you enjoyed the report.
Your use of a Ransom rest for this air rifle has left me confused. I am only familiar with the pistol version of the Ransom rest that uses custom-made grips to hold the gun. I never heard of a Ransom being used on a rifle before.
B.B.
Well, I may have used the wrong word. It is a Caldwell zero max rifle rest that I have screwed in Velcro to grip the gun. So, I am not sure exactly what I would call it.
Trevor,
A Caldwell rest I can understand. Thanks for explaining that.
B.B.
Definitely not to be compared to a Ransom… As mentioned, Ransom use custom frame “inserts” for pistols. You take the pistol grips off, and these plastic (?) pieces that fit the metal frame are used to grip the pistol in basically a vise. (The vise is on a tensioned pivot to handle recoil). There is a lever that is used to press the trigger. The rest is clamped to the bench/table and lined up. There is no hand contact anywhere with the gun when firing.
