Something many shooters ignore is dry fire practice. Having shot with and having coached small bore championship collegiate rifle teams, I firmly believe in dry fire practice. Teaches trigger control, follow through (really important for muzzleloaders), flinch resistance and the rhythm of the sights in the firing positions. It does a lot for strength of muscles used in the firing positions too. I tried to get the shooters to fire about a ten dry fires for every live fire. Had a pretty good impact on scores.
