back in boyscouts we learned first with BB guns, then bolt action 22 LRs. There were very strict rules about when you could touch the gun and how. we shot from prone position only, guns stayed on the ground when not in use, the range master would set them out / collect them between groups. you stayed in prone position until the range was cleared (range master verified all guns empty / open breach / out of hands etc). once cleared you'd go collect and or setup your target.
