Im shooting 3/4oz 9s at 1490fps. No shot in birds yet, although all close shots. Im shooting skeet and LM chokes, which is a 30 and 35yd setup in my gun. If I go LM/IM its 35yd 50yd+ (it has adequate penetration to about 80yd). Im not going to shoot a pheasant that far, but i guess its there if I ever need it. I shoot it because i am tired of finding lead in my birds. I am loading my own and right at $2/shot. At 300 pellets, its a dead bird every single time the pattern connects.
