Beeman HW 70A air pistol: Part 2
by Tom Gaylord, a.k.a. B.B. Pelletier
Okay, there’s some interest in this Beeman HW 70A, but many of you have avoided it like I have. Let’s see what it can do.
First, the cocking effort. HW advertises 21 lbs., however the test pistol registered 27 lbs. on my bathroom scale. While that may not sound like a lot, remember this is a close-coupled pistol, so there’s no long lever like you have on a breakbarrel rifle. So, 27 lbs. does feel like a lot.
The trigger-pull, on the other hand, is very light. The test pistol releases at just 2 lbs., 3 ozs. And that’s after I adjusted it to be heavier. I’d gotten it so low that it surprised me when it went off. That felt too dangerous; but where it is now feels pretty good.
Premier 7.9-grain domes
The first pellet to be tested was the Crosman Premier 7.9-grain pellet. It averaged 371 f.p.s., and the spread went from a low of 364 to a high of 381 f.p.s. At the average velocity, this pellet generates an average 2.43 foot-pounds of energy at the muzzle.
Next up was the 7-grain RWS Hobby. As light as they are, I expected Hobbys to be the speed demons of the bunch, but they weren’t. Hobbys averaged just 363 f.p.s., with a spread that went from 354 to 372 f.p.s. At their average velocity, Hobbys produced 2.05 foot-pounds of energy at the muzzle.
Beeman H&N Match
The last pellet I tested was the Beeman H&N Match pellet. This wadcutter weighs 8.18 grains and was the heaviest pellet I tested. The average nuzzle velocity was 383 f.p.s. — making this not only the heaviest but also the fastest of the 3 pellets tested. The range went from 371 to 395 f.p.s. At the average velocity, they generated 2.67 foot-pounds of energy at the muzzle.
I was puzzled
After testing these 3 pellets, I was puzzled about the velocity claims of 440 f.p.s. by the manufacturer. I thought that Hobbys would at least get close to that number, but as you can see, they were the slowest pellets of all, not to mention being the lightest. That made me wonder why they would be so slow. It seemed that they were also the pellet with the largest skirt, so maybe the gun was having difficulty overcoming the pellet in the breech. That’s when I thought about deep-seating each pellet with the Air Venturi Pellet Pen and Seater to see how it would change — if at all.
Deep-seated Hobbys now averaged 419 f.p.s. and the spread that had been 18 f.p.s. before was now down to just 9 f.p.s. The muzzle energy went up from 2.05 foot-pounds to 2.73 foot-pounds.
H&N Match also increased, but the difference was much less. After deep seating, they averaged 392 f.p.s. and generated 2.79 foot-pounds at the muzzle. The total spread dropped from 24 f.p.s. to just 7 f.p.s.
Even Premier lites increased from 371 to 380 f.p.s., bumping the muzzle energy to 2.53 foot-pounds. And the total spread dropped from 17 f.p.s. to just 8 f.p.s.
Deep-seating seems to help calm this gun down and also to boost velocities. I guess I’ll have to try it when I test the pistol for accuracy, as well.
Impression thus far
Though the velocity seems to be a little low, the firing behavior is smooth and positive. The pistol feels right when it fires, and I think it’s going to turn in some surprising accuracy. But we shall see.
