I'm asking for some first hand experience. Years ago I had a "C. Sharps" in 45-70 which I loaded for and it shot very well with the Lyman Postell bullet. I had to part with the rifle after losing my job. My nephew is sending me his "Shiloh Sharps" 45-70 to work up loads for.. I remember that it had a chamber shorter than mine and we were unable to seat the Postell loaded rounds( I used 62.5 gr Goex Cartridge grade, compressed with fiber wad). I furnished him with several cast bullets to use and he said that even with drop tube and compression die he was not able to seat it deeply enough to use 60 gr of 2F. I was thinking of trying a lighter, shorter bullet, but thought that someone surely must have already "cracked that nut". I guess I could do a pound or chamber cast, but I was trying to explore some choices from your success. Thanks in advance for looking and sharing.
