I don't think that you need expanding bullets in .458" caliber.
I use hard cast bullets on hogs and they work just fine.
My Ruger #1 likes this load:
Black Lion 398 grain FNGC over 41 grains H4198 and Federal 215 (yes, magnum) primer. I haven't clocked it yet but velocity should be over 1700 fps.
Accuracy is good, and it burns very cleanly; no unburned powder and the cases don't get smudged.
The difference is the magnum primer.
Good Hunting.
