The more I shoot this gun, the more I like it. Did some work today on adjusting the hammer spring. Got the JSB 18s flying around 880fps and shot around 50 shots on target, then decided to record the remaining shot string on my chrony to try and figure out where the regulator is set. Got 60 shots from 160bar to 95 bar! So in total that is 110+ shots on a fill at this setting.
From the chart below, I am guessing that my reg is set around 120 bar, because it started to increase in velocity around that time. I still have not been able to max out the velocity with the stock hammer spring, but at this power level I am really pleased with the shot count and accuracy. My only complaint about the rifle is that you don't know where your regulator is set, but that is really minor.
