We’ll look at the 2250XE today for velocity. I just want to remind you that I predicted this carbine would shoot faster than the advertised 550 f.p.s. and, indeed, it does.
This CO2 air rifle uses a single 12-gram CO2 cartridge as a power source. Normally, I would guess that we would see about 40 good shots from a cartridge, but today I counted them, so we’ll all know for sure.
I mentioned in Part 1 that I really liked the trigger-pull. Today, I’ll say more about it. At first examination, it feels like a single-stage pull, and that’s what the specs say it is. After using it a while, I could feel a definite hesitation in the pull that turned it into a two-stage pull for me. You have to be careful to not fire the gun by pulling too fast; but if you pull in a controlled way, the trigger does have a two-stage feel, which makes it much more precise.
I measured the trigger-pull at 5 lbs., 2 ozs. several times, and it did not vary from that weight. With the trigger shoe that came on the gun, this trigger will really help in the accuracy test because I will know exactly when it’s about to break.
I tested the potentially fastest pellet first. The RWS Hobby is one of the lightest lead pellets on the market, and yet it’s often very accurate, too. We’ll see about that in Part 3, but for today the average velocity was 584 f.p.s., with a spread from 578 to 591 f.p.s. So, there’s your faster pellet. It generates 9.01 foot-pounds of energy at the muzzle, on average.
Next, I tried the ever-popular Crosman Premier in the cardboard box. This 14.3-grain pellet averaged 546 f.p.s. with a spread from 541 to 552 f.p.s. That’s a nice tight spread and a 9.47 foot-pound average muzzle energy. Of course, this is a CO2 carbine; and like a pneumatic, CO2 guns usually generate more energy with heavier pellets.
The last pellet I tested was the 15.9-grain JSB Exact dome. These pellets should be very accurate in this carbine. They averaged 516 f.p.s.; but this was the third shot string, and I noticed a definite decrease in power during the string. The first shots were in the low 520s and the final five were at or below 516. From what I saw, I calculate that this 2250 gets about 25 stable shots from a CO2 cartridge before the power starts dropping. You can shoot it for 30 shots, but after that the velocity starts dropping fast.
On shot 31, I went back to the Hobby pellets and now got a velocity of only 567 f.p.s. Shot 35 was going 549 f.p.s. and shot 40 went 462 f.p.s. After that, you’re risking getting a pellet stuck in the barrel.
I loaded a fresh CO2 cartridge in the gun and ran a second string of JSB Exact pellets. This time, the average velocity was 530 f.p.s. with a spread from 528 to 534 f.p.s. At the average velocity, the carbine is putting out 9.92 foot-pounds of energy.
There aren’t as many shots as I would have expected from a CO2 cartridge, but the gun is definitely faster than advertised. I expect to see some good accuracy from this carbine, based on the fact that it has a Crosman barrel and such a good trigger.
