I have been snapping in (dry firing) to practice trigger control with my rem 700. I have been using snap caps. My question is will it hurt my rifle if I don't use the snap caps?.
I go back and forth with this one. I often use a spent casing but snap caps are cool.
I would like to see one broken from dry firing, never heard of it on a modern 700
Do not know about a 700 but a M9 you will need to replace the firing pin eventually. I would think eventually you would need to replace something but that will be a long time from now.
