I don't know much about pellet size in relation to your FPS that you gun has. I've been reading that your choise in pellet shape and gr. has a big difference on how clean your kill is. So the higher FPS, the heavier gr. you are going to want right? Does anyone know what size gr. to put in a 650fps airifle that would give me the best results?
