Just picked up the rifle I bought off Gunbroker. Description said it was a martini action with a .32 bore. The thing is in nice shape, and although it technically is a martini,it is stamped A. Francotte Patent, which is a plus as far as I'm concerned. I haven't had a chance to slug the bore and make a chamber cast yet, but a .32 s&w case won't go into the chamber, but a .30 cal j-word goes in the muzzle without force. I'm thinking it is chambered in .300 Sherwood or .300 Rook, but then the bore should be .301. Any help would be appreciated.
