RL-7 should be speedy with those 380-gr WFN coppers. 53.0 grains of that in my 45-70 Marlin 1895 22" gave over 2000 fps with 400-grainers. Same charge of IMR-3031 was just a little over 1800 fps, satisfied Elmer just fine. I guess Sir Larry will be working up towards 70 grains of RL-7 in the .458 WM. Keep us posted, please.
