The 720 grain LFNGC will do 1675 fps in the .458 Win mag with Alliant powder. The .458 Lott will do 1900 fps.

Groups are in the neighborhood of 1.5" at 100 yards

I'm working on some 750 grain WFNGC's in .585. They're cast ad ready for sizing and lube. What a chunk of lead!! Now all I need is a 577 double!!!

Next project - 400 grain LFNGC for the .375. I'm shooting for 2000-2100 fps.
