Black powder rifles

FWIW, I doubt it's a Loyalist Arms gun. They use seamless tubing for their barrels.

IIRC, that was mentioned on one of the other threads I referred to, but a subsequent contribution from a metallurgist indicated that, in the industry, the term "seamless tubing" can simply mean that the product is formed with a seam, but that it then undergoes a further rolling/burnishing process (internally and externally) to eliminate any roughness or detectable extra thickness along the seam line ....
