RE: I want to get a BP rifle...
I agree that you should look at the NEF or the H&R as they are basically the same rifle. I think one requires firearm rules as it has interchangeable barrels with cartridge barrels. If you are familiar with a single barrel shotgun you should really like these. I got a similar gun for my brother in law as he was an old Illinois rabbit hunter. I got the Traditions Pursuit but due to a terrible trigger I would not recommend the Traditions. It also has a spanish barrel which some believe is not as strong or safe as the american steel barrels in the NEF and H&R. I think these are going to be your best bet dollar for dollar if you want to stay on the low cost side of the game.
