From the metal on metal perspective...
The firing pin in a recoiled position against a spring's tension.
Pulling the trigger, you release that spring, you propel that firing pin forward and into the receiving end of the "receiver".
A snap cap aides in the impact of that firing pin against the rear of receiver action.
I have snap caps for every bolt gun I own, as well as my .45's
If you don't? That's your choice.
My inclination is that you are NOT practicing as much with your guns as we are with ours.
