On my first try I got a total of about 22 powerful shots before the velocity started dropping linearly. I won’t give the velocities, because they aren’t representative. But I will tell you that I got velocities that were just as high on this try as on the next one.
Cartridge failed to pierce
With a shot count that low I knew what had happened. One of the two cartridges had failed to pierce. The rifle was running on a single cartridge. In the beginning that doesn’t make any difference, as CO2 is a self-regulating gas, But you do run out of gas sooner, which is exactly what happened.
Sure enough, when I exhausted the gas and removed both cartridges, the top one hadn’t been pierced. No problem. Just screw the piercing plug in deeper next time. I could even reuse the cartridge that hadn’t pierced!
This time I screwed the piercing plug in as far as it would go. The shot count this time rose to 50+ shots, and I will tell you more about them as we go.
H&N Finale Match Light
The first pellet to be tested was the H&N Finale Match Light with 4.5mm head. These averaged 609 f.p.s. with a high of 618 and a low of 598 f.p.s. The spread was 20 f.p.s. On the first try with a single CO2 cartridge this same pellet averaged 604 f.p.s., so the difference isn’t that great.
At the average velocity the Finale Match Light produced 6.23 foot-pounds of energy at the muzzle. On the first try it produced 6.13 foot-pounds.
Next up was the 7-grain RWS Hobby. They averaged 627 f.p.s. with a high of 651 and a low of 610 f.p.s. There’s your 650 f.p.s. claimed by Umarex.
The spread was 41 f.p.s. At the average velocity Hobbys produced 6.11 foot-pounds of energy at the muzzle.
Air Arms Falcon
The last pellet I tried was the Air Arms Falcon dome. They averaged 608 f.p.s. with a high of 633 and a low of 596 f.p.s. That’s a spread of 37 f.p.s. At the average velocity they produced 6.02 foot-pounds of energy at the muzzle.
The first time I shot the rifle with just a single cartridge pierced the velocity spreads were very large, and the velocity dropped off with each shot. I had to wait 30 second between shots to get the velocity to stabilize.
The second time
The second time I did pierce both cartridges, and when I said I got 50 shots on them, that wasn’t actually the case. The piercing plug was still under too much pressure to release the remaining gas, so I loaded another 10 Hobby pellets and shot as fast as I could and still record the velocities. The first shot went out at 464 f.p.s. and shot number 10 was going 327 f.p.s. So, when you are outside plinking you can count on 6 full magazines from fresh cartridges.
After the first four strings
I wanted to see where the velocity was after the first 40 shots, so the last “official” string I fired was with 10 Finale Match Light pellets that averaged 609 f.p.s. on the first string. This time the average was 528 f.p.s. with a spread that went from 479 to 567 f.p.s. That spread is 88 f.p.s. and the average power is 4.68 foot-pounds. So the power has dropped off and the spread has become much larger toward the end of the gas.
Velocity with bolt cocked versus just trigger pulled?
If this was a single and double action handgun I would check the velocity both ways, so I checked it by just pulling the trigger and also by cocking the bolt first. There was no difference in velocity either way.
Magazine worked easy
I was pleasantly surprized how easy the magazine removes and installs in the rifle. Once out, it’s also quick and easy to remove the 10-round rotary clip. Removing the mag on a 10/22 firearm can be a challenge, but with the air rifle it’s easy.
The specs say the double action trigger pull is 10 pounds. I have no good way to test it. It’s all of that and maybe a little more, but it is smooth, once the magazine is advanced and the striker starts moving. But the single action trigger pull is quite nice. The specs say 3 pounds. When I tested the rifle I’m writing about the pull registered between 5 lbs. 3 oz and 5 lbs. 4 oz. I guessed it was a pound lighter. It is a single-stage pull that way and you can feel the trigger moving but there is no creep.
Accuracy testing comes next. I’ll start with the open sights, then I’ll install an Axeon R47 dot sight that Umarex sent to jazz up the rifle and test with that.
The Ruger 10/22 Air Rifle is a realistic lookalike that shoots 17 .177 caliber pellets as fast as the trigger is pulled. It also has the ability to have a lighter trigger when the bolt is cocked. I’m really hoping it is as accurate as it looks. If so, it may be the one to get!
