Out if the 15" you can push an 18 grain much faster than you'd ever want to shoot a pellet. My brother currently has his tuned as follows, 1750 reg pressure 18 grain at 890 fps for 11 mags or 120 shots.I’m producing 810 fps (18 grains) with the Evol mini and it’s 10inch barrel. Anyone know at what ballpark fps I would be with a 15inch barrel?
