Didnt want to hijack crown thread with this question. Watched a guy loading and shooting a muzzleloader rifle that had a recessed crown. It was made so the patched ball could be thumb seated smooth with end of bore. Then seated with ramrod. Is this something from old traditional muzzleloaders or something that the builder of this gun did to make loading easier? He said gun was that way when he got it years ago. Don't know who built it or when. No name or markings, full length stock, percussion, double triggers, very nice old gun, 45 caliber. It wouldn't be hard to recess a crown if it was something traditional. I'm learning the old craftsmen were capable of doing some amazing work with what they had to work with.
