The other reason for snapping a cap is to help in case there is any moisture in the barrel from sitting. Because I use black powder, I leave the rifle outside due to condensation forming. I do discharge it and clean it every night. Firing a couple of pans of powder works for me then load it and go. I always shoot my guns prior to hunting. Most times its a couple of shots at camp, just in case something is wrong. This wouldn't be possible for some to do. I also go to the range usually in Sept/Oct to do general sight ins.
