Speaking of pieces gentlemen...
A friend of mine has a trapdoor receiver (nothing else) and I was wondering if rethreading a 45 or 50 caliber modern muzzleloading barrel to fit to the receiver would be feasible to begin the process of building a trapdoor replica as a home shop project over the next couple of winters. A piece here and a piece there so to speak until its all together. Purely a blackpowder/pyrodex planned shooter at this point. At this time, I have a 50 cal muzzleloader as a possible barrel donor.
