I stumbled into a business that sells both smooth bore and rifled (1 in 72) percussion muskets in the Northeast. I never knew anyone had a replica with this caliber. The rifled musket would be pre-Minie, for sure. Strangely, not to far from me a battle was fought between Indians and the U.S. Army, back in 1858. The Indians were equipped with a Hudson's Bay variant, of these, and shot the daylights out of the U. S. forces, who were using a fifty cal. smooth bore musketoon with three balls. The Indians were causing major trouble from out to 275 yds., and the U.S. forces were only effective out to about fifty yards. This fracas has come to be known as the "Battle of Rosalia". and the site, is between Colfax and Spokane, in Eastern Washington State. Can anyone give approximate recoil and powder charges for something like this? I think there is a double barreled Kodiak, in 72 cal., which should be pretty close, with PRBs. Maybe this is just a 16 gauge, but I don't know.
