RE: dry firing
You can dry fire that gun every day for the rest fo your life and it won't hurt it at all.
A snap cap isn't going to do squat to slow down or cushon a bolt actions firing pin. The spring pushing it is just too strong. The firing pin actually has a shoulder machined on it and this shoulder makes contact with a shoulder on the inside of the bolt and this is what stops the firing pins foward movement. Snap caps are jsut someting they tell you that you need so they can make more money.
Now snap caps are a good idea to use in side X side and O/U shotguns and rifles becasue the firing pins just float there, some on a very thin return spring, and can get hung up. But for a bolt action, or pump, or semi auto they aren't needed.
