Do any of you have any experience using Elmer Keith's 45-70 classic load of 53 grains of 3031 with a 405 grain Jacketed
bullet.
I tried 51.3 grains of 3031 with a lead cast bullet 405 grains in a Marlin 1895 CB .I seemed to be getting a loss of accuracy.
The cast bullets seemed to be doing better with less powder
say 46 grains of 3031.I suspect it was my choice of bullets and gas blow by in a cast bullet without a gas check.
