Remember this report because I’ve done something with this rifle that I don’t normally do. To save some time at the range, since good airgun range days in Texas are often hard to come by, I’ve already tested the Hatsan AT44-10 Long QE at 50 yards. I took it along last week when I was testing the Shamal, and the day was perfect for 50-yard shooting. I’m not going to tell you the results today; but when I do show them, a lot of you will be impressed.
Today is velocity day. Normally, I would have already tested velocity when I went to the range, but this time when I shot for accuracy I had no idea how fast this rifle was shooting. You can’t tell from its muzzle report, either, because the AT44-10 QE is as quiet as a Benjamin Marauder. When I tested it today, Edith thought I was shooting the Benjamin Trail Nitro Piston 2 in my office, instead of a powerful PCP.
The first pellet I tested was the 16-grain Air Arms Diabolo Field pellet, which is a dome. I’ll show you the first 20 shots, then explain what I’m doing. The rifle was first filled to the recommended 2900 psi (200 bar).
The average for this first string of 10 shots was 1000 f.p.s. The high was 1019, and the low was 975 — so the spread was 44 f.p.s. At the average velocity, this pellet generated 35.54 foot-pounds of muzzle energy.
The next 10 shots with the same pellet, and still shooting on the same fill, looked like this.
The average for this string of 10 shots was 946 f.p.s. The high was 970 and the low was 923, so a spread of 47 f.p.s. At the average velocity, the pellet generated 31.8 foot-pounds on this string.
The spread for the entire string of 20 shots was from 923 to 1019 — which is 96 f.p.s. We will look at where the pellets impact on the target with this pellet for both strings in the next report. And, yes, I have focused on this specific pellet.
What to look at
I showed you these 20 shots for a reason. What you see is that the velocity drops from the first shot to the last, with a couple exceptions. Perhaps the maximum fill pressure of 200 bar is understated for the rifle I’m testing, or maybe my gauge doesn’t agree with Hatsan’s gauge for the starting pressure. Some shooters would be tempted to fill to a higher starting pressure to see how the power curve might change; but since I’m at the recommended maximum, I’ll stay where I am.
The air reservoir had 1750 psi remaining after these 20 shots. That’s about the maximum number of shots you can get with this pellet if you’re looking for the best accuracy at 50 yards. If you confine your shots to 35 yards and less, I’m sure there are another 10 shots in the reservoir. The shot count depends on how you’re shooting the airgun. Please keep this velocity relationship in mind as we proceed because I’m not going to record the velocity of the other pellets 20 times. But you know that the velocity will continue to drop with them just as it does with this pellet.
Next up were 28.4-grain Eun Jin domed pellets. We know that these heavy pellets will probably be the most powerful in this rifle because it’s a pneumatic. Pneumatics usually do their best (achieve the most power) with the heaviest pellets.
This is a very long pellet that just fits in the circular clip, but it did fit and functioned fine. I filled the gun to 2900 psi, again, and shot 10 pellets that did the following:
The average for these 10 pellets was 867 f.p.s. The high was 892, and the low was 836 f.p.s. — so the spread was 56 f.p.s. Again, the velocity dropped almost linearly; and at the end of 10 shots, the reservoir was holding 2250 psi. This heavier pellet used more air than the lighter Air Arms pellet that shot 20 shots and ended at 1750 psi. At the average velocity, this pellet generated 47.41 foot-pounds at the muzzle. Remember that number.
The final pellet I tested was the 11.9-grain RWS Hobby. The gun was filled to 2900 psi once more, and another string was fired.
The average for this string was 1107 f.p.s. The high was 1128 f.p.s., and the low was 1078 f.p.s. The velocity spread was 50 f.p.s. As with the first 2 pellets, the velocity fell off linearly. At the average velocity, this pellet produced 32.39 foot-pounds of energy at the muzzle. The reservoir pressure after this string was 2500 psi.
We’ve learned that lighter pellets will use less air than heavier pellets. If you just plink at distances below 35 yards, you can probably extend the number of shots per fill to 30. Hatsan says you should get 30-40 shots per fill, and that’s about what I see from this test. I’m probably going to test it at only 50 yards, although I haven’t yet made up my mind on that.
There doesn’t seem to be a flat spot on the power curve. The velocity just drops from the first shot to the last. We’ll see next time how that affects accuracy.
Velocity and power
Hatsan says you’ll get up to 38 foot-pounds from this rifle in .22 caliber. In fact, I got over 47 foot-pounds, so they’re being very conservative. They also say the top velocity with lead pellets should be 1070 f.p.s., yet I saw over 1100 f.p.s. with RWS Hobbys, which are lead. Again they are conservative. Hatsan has the reputation of advertising realistic velocities and power for their PCPs by using only lead pellets, and this test confirms that.
I adjusted the Quattro trigger and got it to my liking. Stage one now requires 1 lb., 3 oz. and stops at stage 2 most of the time. Stage 2 releases at 3 lbs., 4 oz. There were a couple times when the rifle fired before I could feel the trigger stop at stage 2. I think that may have been partly my inexperience with this trigger, but it made me more cautious. At any rate, the trigger is very adjustable and should please most sportsmen.
The AT44-10 Long QE is an extremely quiet air rifle — especially when you consider the power. Stay away from pellets that go supersonic and you won’t bother too many people when you shoot. It’s quieter than most breakbarrel rifles. You should be able to shoot it without bothering the neighbors, unless they’re listening for you to shoot.
So far, the AT44-10 Long QE is living up to its advertised potential. I just happen know the rest of the story as well; so, although I’ll make you wait a while longer, this is going to be a story you will want to read. If you’re looking for a quiet, powerful, accurate hunting air rifle, watch this test closely.
