Hi, Im trying to understand the target practice requirements for the Rifle Merit Badge. For the .22 cal rifle it says: Adjust sights to center the group on the target* and fire five groups (five shots per group). According to the target used, each shot in the group must meet the following minimum score: (1) A-32 targets - 9; (2) A-17 or TQ-1 targets - 7; (3) A-36 targets - 5. Questions: - Does only one of the 5 groups need to meet the criteria that each of its 5 shots have the minimum score? - Do you need to use iron sights, or is a scope permitted? - When shooting from bench, can the rifle be supported with sandbags? Thanks, Alex
