I am a bit of a newbie, a few years and a 100 shots or so. I have been using the Pyrodex pellets and like them for ease of use. Can't even find 777 pellets around here in Connecticut, I have tried. any way with 30 & 50 grain pellets you have quite a few options, 60, 80, 90, 100, 110, 120, 130,140, 150. I mean how close do you need to be???
