Modern commercial ammunition is loaded very, very conservatively. If you load your own you can do significantly better. I'll give you a sneak preview of the results so far-
100gr. copper-washed LRNFP (unknown if this is commercial or handloaded.)
779 fps. 135 ft./lbs SD: 23
115gr. LRNFP (unknown if this is commercial or handloaded.)
761 fps. 149 ft./lbs SD: 13
96gr. LRNFP, 3.7gr. of Unique with a CCI500 small pistol primer
744 fps. 118 ft./lbs SD: 35
This load is rather light, as you can see. I usually load this bullet over 4.0 gr. of Unique; I’ll be testing that load in the future.
96gr. LRNFP, 12.7gr. Hodgden Triple 7 FFFg (black powder substitute) with a CCI500 small pistol primer
837 fps. 149 ft./lbs SD: 12
This powder charge is measured by weight, not volume (as was more typical with Black powder.) Triple-7 yields slightly higher velocity than black powder, but cannot be compressed as much. On the balance this load is probably a fair approximation of the original load for this cartridge.
