Consider this load data to be SAAMI satisfying for the .458 Winchester Magnum,
this is correctomundo IMHO for
3.340" Max COL
60,000 psi MAP
24" rifle barrel length
1:14" twist
0.458" to 0.459" groove diameter
Hornady, W-W Super, or Remington brass of 94 to 95 grains water gross,
and Large Rifle Magnum Primer of the F215/WLRM/CCI250 types.
