As a dedicated shotgun and black powder shooter I feel comfortable in saying that most "black powder" rifles will not have the recoil of a 12 or 20 ga. shotgun. That said, it certainly depends on the load you use. I have no idea about youth models. Black powder shooting is a lot of fun, but I am afraid that with the flood of inline rifles out there today it is a sport quickly being relegated to traditionalists. As you will note I am a bit of a traditionalist. If you want a true black powder muzzleloader I would recommend looking around gun shops for a deal on a used T/C Hawken, Cherokee, Seneca or similar (the latter two would be smaller frame guns). It would be a good gun and would teach a young shooter a little history as a bonus.
