Used Lyman Great Plains Rifle.
That can be your gain as there are always a few available and at a reasonable price. Why does it have to be U. S. made? I would not have a problem with Traditions or Cabelas. Staying under your $300 might be a problem. Good luck and you should not have a problem but you got to get out there and look.Nobody wants them!!

You're not going to find a traditional muzzleloader made by anybody new for under 300 bucks.
