Hi, newbie here, I bought a Ruger .30 Carbine with the express intention of rechambering it to 32-20 loaded with .308 diameter bullets. I later discovered that the loaded 32-20 brass would be too small in diameter to fill the Ruger cylinder throats. My next choice was one of the 30 wildcats around in the past, 30 whisper, etc. Has anybody any experience or knowledge with this? Thanks, George M.
