I wanted to test the RAW Chassis System HM-1000X rifle a second time at 25 yards today, but something happened. Reader Kevin mentioned that The RAW should do its best with JSB Exact Monster Redesigned pellets at 100 yards. Then John McCaslin, who makes the RAW, told me the same thing. He said the rifle was tuned at the factory for that pellet. Well, I looked for them and they are sold out everywhere — of course. But I have a connection and was able to secure a small supply of that pellet for testing. It won’t be here until later this week, so I had to set the RAW test aside for today.
Today I test the Beeman P1 pistol’s velocity. And I realized that in the last 12-part report I tested the pistol that I overhauled. Instead of retesting that pistol so soon, I have decided to test the P1 that I got back in 1995 for The Airgun Letter. Here we go.
R10 Match Pistol
I will test the pistol with three pellets. Since I have tested Beeman P1s a lot, I know which pellets they like the best. We will start with the RWS R10 Match Pistol pellet.
R10 Match Pistol High
On high power the R10 pistol pellet averaged 571 f.p.s. The low was 564 and the high was 581, a difference of 17 f.p.s. At the average velocity this pellet generates 5.07 foot-pounds of energy.
R10 Match Pistol Low
On low power the R10 Match Pistol pellet averaged 462 f.p.s. The low was 460 and the high was 465 — a difference of 5 f.p.s. At the average velocity the energy was 3.32 foot-pounds.
Sig Match Ballistic Alloy High
These pellets didn’t exist when the P1 was new. But past testing has shown them to be very accurate. On high power they averaged 612 f.p.s. The spread went from a low of 599 to a high of 618 — a difference of 19 f.p.s. At the average velocity this pellet generates 4.37 foot-pounds of energy.
Sig Match Ballistic Alloy Low
On low power the Sig Match Ballistic Alloy pellet averaged 477 f.p.s. The low was 475 and the high was 481- a difference of 6 f.p.s. At the average velocity the energy generated was 2.65 foot-pounds.
Crosman Premier Light High
The 7.9-grain Crosman Premier Light pellet that Crosman no longer makes averaged 499 f.p.s. on high power, The low was 495 and the high was 504 f.p.s. That’s a difference of 9 f.p.s. At the average velocity this pellet generated 4.37 foot-pounds of energy.
Crosman Premier Light Low
On low power the Premier Light averaged 401 f.p.s. The low was 396 and the high was 408 f.p.s. — a difference of 12 f.p.s. At the average velocity this pellet generated 2.82 foot-pounds of energy.
I should mention that the P1 does have a dry-fire capability without cocking the gun. The top strap is released and pulled up as high as it goes without effort, then pulled up a few more inches until a faint click is heard. It happens before the low power cocking notch is reached. Close it again and the trigger is set but the pistol is not cocked.
When you pull the hammer back the top strap is released. It rises this high without effort. Pull it up about this same amount again and the trigger is cocked without cocking the pistol. That allows for a dry fire.
Well, shut my mouth! Reader Stephan from Germany commented that all he had to do was just pop the top strap up and the trigger was cocked. I just tried it and he is right! Forget what I said about lifting the top strap a little more. Just pop the top!
This is the pistol whose trigger I modified back in 1996. It now has a two-stage pull with stage one taking 12.6 ounces of effort and stage two breaking cleanly at 1 lb. 13 oz. It’s better than it was after the trigger modification, but still just a bit too light for me. It would be fine if this was a rifle or even a 10-meter pistol, but not a 1911A1 frame that requires me to hold the weight of the gun while I pull the trigger. Because it has a 1911A1 frame I would like the trigger to break at 3 lbs., but it is now adjusted as heavy as it will go with the trigger mod I did in 1996.
The P1 isn’t that hard to cock, but it does require a technique. You invert the hand that pulls the top strap up and forward. That sounds odd but once you have done it a few times you’ll see how easy it is. If you don’t do it that way, and I have seen many people who refuse to, then the P1 is a bear to cock! I think it feels three times harder than it is, if it isn’t cocked correctly.
To test the cocking effort I broke the pistol open and rested the inside of the top strap on my analog bathroom scale as I pressed down to extend the top strap. Guess what? My P1 is even easier to cock than I had thought! Cocking to low power takes just 11 lbs. of effort. You can horse it higher by going too fast, but 11 lbs. is the max if you do it right.
To go to high power the effort spiked to 12 lbs. in one place in the cocking arc (just after low power is achieved) and then dropped back to 8 lbs. for the rest of the stroke. In other words, Yogi, the effort I had to apply in the longer cocking stroke was mostly less than the effort for the shorter one. I wanted to say that last week when you made your comment about short and long cocking strokes with breakbarrels, but this P1 proved it today.
I am only reporting the results I see. Now, the length of time you are applying the force has to be longer if the stroke is longer, so maybe that’s what you meant?
That’s the power of the pistol I will be testing for you. From my experience with this airgun, this one is right where it should be.
