While individual councils vary, scouting is in general very supportive of the shooting sports. The main limitations in most areas are the lack of trained instructors and the availability of adequate equipment. Here's how you or your club can take the first steps to get the Boy Scouts in your area shooting muzzleloaders at their camp. The number may be for the local council, or one of their district representatives. Ask them about their council camps and the shooting program now being carried out.
Chances are that summer camp is the only time that shooting is offered.
Get the number of the camp ranger, and also the council executive. Talk to both of them about how you or your club can help to provide shooting opportunities at their camp range throughout the year, as well as assisting during the summer camp season. Get some copies of the rifle shooting and shotgun shooting merit badge pamphlets from the local scout office, and carefully read the requirements. B.S.A. also publishes a Shooting Sports Handbook, as well as Health and Safety Requirements for the Shooting Sports. Read them all if you can.
