NO, Davey: The guns that go with the bags in the museums all have coned muzzles. That is what he observed in his travels, but it didn't sink home unti he was going through all his notes to write his book that there was this common thread through all the guns all over the country from that Pre-civil war period. The hunting guns had coned muzzles, while the target guns had flat crowns, and required and did have short starters either in their bags, or had a loop or some other provision for keep a short starter handy in the bags.
The reason I remark about the article is that my brother had just bought an old gun, convernted to percussion in the 1870s or 80s, but that used a barrel that was obviously much older. We could not determine the true caliber becuase it was smaller than the .36 cal. rod I had at the time. The muzzle was a worn, 38 caliber! He sent the barrel off to a man out east to take the breech off, clear the barrel examine it, and if need be, fresh the rifling, or rebore it to a larger caliber. Because of deep pits, he had to have the gun rebored to .42 caliber, which removed the coning at the muzzle entirely. The gun shoots beautifully in the new caliber, but he still cusses it when he has to use that short starter to get the PRB going down. When we both read the article in Muzzle Blasts, and he talked to the barrel maker who did the work, it became clear that the original barrel had been coned. We laughed about that, and then regretted we had lost the coning. We didn't know then that anyone was making tools to do that. ( Tnank you Joe Wood.)
