Several. Before I put up the first target, we go over the safety rules. I then, show then how the firearms we have that day work. Then eyes and ears. Then hang targets. Then I load them. I set them on the table, barrel down range. Then, I pick up a pistol, and fire some slow, controlled rounds, so everyone can see what is going on(slides moving, flames coming out of cylinder gaps and so on). Then I reload, set it down, and instruct the “shooter” to pick up the gun, without touching the trigger until instructed. It’s always a good time. Never had a complainer yet.
