RE: muzzleloader
I agree with Cayugad. I have 2 Bobcats that I bought for my kids to learn on, one 50, one 54. Both shoot well with patched round ball and work well with some conical loads. The sights are very basic but can be upgraded. Both of mine have the plastic stock and are very light. I've added slip on recoil pads so the kids don't get beat up.
I found that 3F powder works best in them, 2F seemed to cause some misfires, possibly due to the larger granules not getting down under the nipple as well. I also use a hot #11 cap to help ensure ignition.
They are a good basic gun that doesn't cost an arm and a leg. Besides, they are a lot of fun to shoot.
