I am brand new to this target shoot stuff but just bought rem 260 with some stuff done to it and a new night force scope . But the guy that got me into this keeps telling me I need to shoot with same ammo all the time . I am really busy don't have the time to load my own so figured I would buy some that I keep hearing other people use prime ammo well they are shut down at least tell some time next year then meet some guys at the guy show that said shoot berger ammo cant get them to call me back Any help
