So I have today off. Shooting in the back yard.
First time with a PCP. Only shot this once, it was enough to figure out it's an air hog. 25 shots takes it from 2900psi down to close to 2k. I backed the hammer spring adjuster all the way out then tightened 2 turns.
So now I have the chrony set up and this is what I got:
Put 15 JSB 15.89gr over the chrony and got average 786 fps, extreme spread of 9 fps, SD=3.
Shot 10 H&N Barracuda 18.13gr AVG=756, ES-10, SD3.
Started at 2900-2950psi 25 shots later I'm at 2150'ish. It's only doing 21-23 ft/lbs so why is it such a gas hog?
