I've run literally dozens of scout ranges for Cubbies, Boy Scouts, Venture Scouts and Girl Scouts. I was the shooting sports trainer for BSA Trans-Atlantic Council in Europe for three years. The tarps on the ground are a familiar site for me. The little guys and bb guns are great but it works better if you give them sand bags for a front rest. A lot of them can't get into a good position AND hold the gun steady. Reactive targets or shoot-n-c are great. We would use that stuff for the first three days of camp and then on the last day use targets from the NSSF to enable us to give them a badge. If they get five on the target they get enough points to earn the free badge. You can check that program out on the NSSF website. What we have done in the past for boys that wanted to shoot "real" guns is to have the shooting program and then declare the scout event "finished". I would then have them change out of their scout uniforms and have lunch. After that we would get back on the range with "real" guns. Last year at Heidelburg I let the ones that wanted to shoot my .376 Steyr, a .308 Tikka, my .357's, 12 gauge slugs, and a really accurate 10/22. They LOVED that part of the day. The best one was getting my Venture Crew on the range with some SF guys and their M4's.
Man did they love those bursts!
