Sir Larry, you're gassing her up pretty well, if accuracy is there that'd be a great load at 2600 fps, nice work.
Sir Ron, us using the burn rates of 2230/2460 powders work mighty well with 450 TSX/Woodleigh etc and the 500 grainers, if you/we really want to push the 404 Hammers to max speed in the 458 WM+ mho is to use AA-2015, it's a hell of a great powder and will boost the lighter bullet faster and at safe pressures over the slower burning 2230/2460 powders.
