Most used loads in my No.1 450NE as follows:

1/ 480 grain Woodleigh RSN, 92 grains ADI-AR2209 (H4350), Federal 215 primer, Hornady case, ????fps
2/ 500 grain Hornady RSN, 90 grains ADI-AR2209 (H4350), Fereral 215 primer, Hornady case, 2130fps

24" barrel that slugs out at 0.457"

Usual handloading caveats apply, my rifle, my loads, if you start here you are on your own, etc etc.

I've got a lead bullet load that pushes a 475 grain RNGC bullet at about 1700-1800fps and shoots pretty well, but I can't find it at the moment. Better find that and put it with the others
