Interweb is quite vague on the matter... if you shoot yours...what brand of shells do you use? I thought T22's would be the ticket, but the Chrono says they are rolling about 1250 fps, better with old Dominion fodder... only 1100-1150 fps.
I'm thinking subsonic is gonna be the end desire... that weak arse stuff for acreage owners to use to not offend the neighbors.
