Can anyone run the numbers for me and let me know what the velocity is supposed for the following? I am guessing around 1175 fps. I am shooting an 1874 Sharps copy in 45/70 with a 32 inch barrel, my load is R-P brass, Win LR Primer 26 gr. of Accurate 5744 and a 475 gr. Lyman Gas Checked bullet cast from wheel weight. Thanks for any info.
