There's a guy on YT -upnorthairgunner--He wanted to do basically the same thing. Texan .357.It took him a bunch of tries to even hit a 21" target.
Look at the rail he's got his scope on. It's more like lobbing artillery shells than shooting a rifle.Blue
Thank you all for your input. You should know I have done the math and realize it is not going to be easy but that doesn't mean I'm going to give up and not try... 146gr spitzer has a bc of .456 and with a muzzle velocity of 1300 fps and a zero at 500 yards I will need 89.56 moa at 1000 yards and the bullet will still be traveling at 812fps at target. Your input is strengthening my resolve to achieve this goal. Thanks again!!
Not sure on how safe helium is in an Airforce gun.
Bob, do you have your own website with all these graphs you post, or can you give a link to a site that has all this gun science? I always find it interesting. I'm an engineer, electronics, not mechanical but I eat this stuff up. So thanks.QuoteNot sure on how safe helium is in an Airforce gun.I can't think of anything about helium that would put any additional stress on any part of the gun. It's just that with helium being lighter, you're not wasting so much of your energy accelerating the gas itself, so the energy you save becomes available to push the pellet or bullet. It would be like reducing the weight of a car or other vehicle. At full throttle, there won't be any additional torque on the drive shaft, axle, transmission, etc., but the same force with less mass results in better acceleration.
