So I finally messed with it on Friday. I was getting somewhat eratic numbers although not bad accuracy fps spreads on 15-26. I've knocked it down to single digit spreads and this is a group I managed to shoot at 63.7yds in 5-8mph winds and 10mps gusts from right to left. This is a 7 shot group.I mess with it because I focus on the guns overall vibes and how things look at full bottle vs refill time. I don’t think about efficiency. That’s a regular poppet valve thing.
Yes, the grouping tightened up a smidge, and so did the spread.Good shooting . In all honesty was it worth tuning the gun up and losing shot count really worth it ?
