45-75 SS

45-75-420 was the original Sharps load with paper patched bullets. When you look in a reproduction Sharps catalog you'll find that is factory Sharps loads it made only a 405 gg and a 420 ppb in factory ammo. Yes Sharps had bigger 45 ppb's available as patched bullets but no factory heavy bullet loads for the 45-2.1. The Gov't bullet at 500 gr gg was known as the 1881 bullet for the year it was brought out. Saeco (1881)makes a good copy of it and it's what Lyman tried to emulate with the 457125 mold. The majority of the buffalo shot with the 2.1 were with 400+ gr bullets not 500's. I have been working with FFg and 70-71 grs and the Kaltool 45TGBS mold at .442" in my new Montana roughrider with a 7* leade results are very promising at 422 grs 1-60 alloy. Probably try some of the harder alloys as well and recoil is light in the 12.5# rifle seems like it might make a good offhand bucket load we will see. bobw

I know I am coming to this late but as I am new I have an excuse. Springfield armory also used the 45-75-404 and 45-75-500 in their long range rifles for use in the creedmore they also used 45-80-500 in a 2.4 case according to some history I was reading. They also found there was not enough difference to keep using the 45-80 so they went back to just the 45-70 loaded to 45-75.
