Home Forums Hunting & Shooting Express Rifles and Big Bores Only The great 458 Winchester. Everyone should own one at least once

I got some catching up to do.
First a couple of good loads before showing a shocker.
No scope adjustments, same as last outing, just letting bullets fall where they may at 50 yards:








So a charge of 70.0 grains of AA-2460s is probably going to be ideal for
NEMO loads with 480-500-grain cast bullets at 2150-2200 fps from a 24" barrel.
Make them .461" in diameter and hardcast, for the SAAMI .458 WinMag.

70.0 grains of AA-2460s is about the midpoint of 66.6 to 74.0 grain range recommended for
500-gr Hornady RNSN, for which 74.0 grains yields 2192 fps and 52,864 psi,
3.305" COL , 24" barrel.

70.0 grains, might go down to 69.5 grains to fine tune with hardcast, heh-heh-heh.
