I found this paper cased Remington Shurshot Kleanbore shell when hunting. The top is marked REM-UMC No 12 SHURSHOT and the side just says SHURSHOT KLEANBORE, The bottom, inside the lip says 3 1/4 DRAMS 1 1/8 OZ EQUIV. I havent been able to find anything on the shell online other than antique boxes. It is an unspent shell and i thought it looked interesting, just wanted a little bit of info about it. Any clues would be appreciated.
