just bought gammo fusion swarm 10x in 22ca.

you never know with a springer ..i always settled on crosman premeirs 14.3g .. usually theyll do 1 1/2 or so to 25y and thell be pretty lethal, just have to stalk in and pick your shots .. if it does better you can work that out with time and trying other pellets as you go ... so id zero that baby nice and close about 12-14yds and work your way out with a target till groups open up to 1 1/ 2 or so .. worst thing i used to do is try to zero at 30 or more, doesnt work out for anything ..
