My 2260
« on: April 12, 2019, 06:11:38 PM »
I put a new valve from Alchemy Airwerks and also a power adjuster. I get between 20 and 25 full power shots with the power adjuster turned in as far as I can get before it just wont cock and I'm fine with that, I want it for the lousy tree rats. But what is interesting is what happens whenthe power starts to diminish, you would think that all the shots would start to get lower and lower. Instead they start shooting high and to the right and then they just kind of go all over the place. I never would of thought that. ???

There is more working here than would meet the eye. Barrel vibration is one cause, and velocity is another. One would think that the last few shots would slow down. They do typically, but there can also be a valve dwell issue which can actually speed up a few shots.

Yes. Like any projectile shooting weapon, there are all sorts of things which occur. I mentioned vibration, but there are many other factors.

One would think that if you reduce the velocity, about all that would happen is the groups would drop. They do, but lateral dispersion is normal as well.

Another thing which occurs, is dispersion caused a weight change, even though the velocity is bumped back up. Even different pellet shapes, with the same weight. To say the least, it isn't really an exacting science, but one which can be adjusted to compensate for the dispersions.

Well, not really. Bob Sterne is, in my opinion, the true guru here within.

I grew up with guns, including airguns, in a sporting goods store in Kansas City. I have been lucky over the years to shoot a lot of weaponry, others can only dream about. I've even hunted on the dark continent—Africa. But a few years ago, I got back into shooting airguns, and the powder burners have taken a back seat. I ended up with this site almost by accident, as I didn't want my previous donations to same, to go to waste. So nowadays, those long-range shots are more like 150 yards. I have taken game (pigeons primarily) out to 280 yards, but those shots had a bit of luck impressed upon them!

And I have to say, that airguns sort of grow on you, and you get to the point of convincing others to join you. For example, the owners of the farms where I shoot most of the time, are now both air gunners! And PCP at that! They are fun, and you will learn more here, especially by reading Bob Sterne's part of the site.

Oh. I should mention that Steveoh, is the other part of the site ownership. He and Kevin are both into large bores. Although I have a 9 mm, it is my 25s which get all of the use.
