I have yet to shoot any groups. Gun doesn’t even have a scope on it yet. I do all my chrono work in my shop 3ft from the muzzle into my indoor backstop.

Fr8rbum, 48 shots were from 3000psi down to about 1700psi. Just under 5% ES. If I start at 2800psi and only shoot 40 shots, the ES drops to 3%.

I am just experimenting with some ideas right now. If you saw the valve and hammer spring, you would never think this gun would do what it is doing.
