I am looking for the drawings and specifications for Snider .577 [.58 Caliber] cartridges, and recently dicovered there are at least 5 distinctly different cases, one similar to [identicle to?] the .577, or possibly closer to a .577/.450 [where the shoulder is], to a tapered straight wall cartridge, and lengths from 1.5 inches to 2.75 Inches and possibly longer, one that appears to be slightly tapered with a hint of a shoulder, somewhat as if one were to lengthen a .44-40 cartridge.
I have found a few pictures, some questionable as to authenticity, but no reliable dimentional dwarings, or certainty as to the cartridge[s], and no timeframe for what appears to be dimentional or design changes.
To make it more conusing, some people use a 20 ga. hull, from 2 inch to 2.5 inch long, with a round ball or short conical, while others say a brass 24 Gauge brass cartridge is correct.
I recently aquired a Snider, Enfield-Snider conversion, or commercial Snider, the version of which I still need to do much research. Just now I am simply attempting to gather information on the cartridge, or series of cartridges, or modifications of cartridges, for the Snider.
… and desperately trying to figure out where the heck I put at least three blocks of Cerrosafe…
This image of shot cartridges is from The Cartridge Collectors web site, THE CARTRIDGE COLLECTOR, for the comparison of cartridge shapes. Using a small mirror, my chamber looks like the two on the far right…
Here is an image from Joe Salter web site:
