Wife and I have decided to take a weekend in October Appleseed class. She is either going to use a 10/22 or her Colt M4 .22 Caliber. I understand the advantages of using a semi auto rifle over a bolt gun, but I have a Savage 93R BTVS in .17 HMR with a scope that I love to shoot. Is .17 HMR caliber allowed in the rim fire shoots ?
