It's my new (old) .577 Snider-Enfield made in 1872
It was one of the first cartrige shooting firearms in the Brittish Empire. Mine is a Mark III with a 1:48" twist, 5 groove barrel. The Mark I & II were .58 cal muzzleloading muskets that had 2" of barrel chopped and a hinged action added, but the Mark III were built that way. It will shoot a .590" 535gr hollow based slug at around 1300fps when I get it up and running (soon, believe me). The rimmed Snider round has a case rim diameter of .75" and is 2" long. It uses a Lg Mag primer (Fed 215) and black powder, clean-shot, or BP like smokeless powder (XMP 5744). Cartrige on the left.
Now I'm just waiting for my .510/460 Long from the smiths.
