SAAMI .458 WM & .458 WM+ velocities mentioned above are from 24" barrel length.
SAAMI .458 WM & .458 WM+ velocities mentioned above are from 24" barrel length.
From my limited research, it seems the Lott will reach 2150 with a wider variety of powders than the win mag will. For an African PH that could be very beneficial.
Wyatt Smith,
You are a wise man.
Then you will be able to use this data safely
(mine from a 24"-factory-barreled SAAMI .458 WinMag Ruger No. 1 at 80*F)
and I am sure you won't work up to it until after you run that SAAMI .458 WinMag reamer into your SAAMI .458 Lott:

Primer used in that W-W Super brass was a GM215M or F215, same-same.
Hornady, Winchester, Remington and Federal cases all have about same gross H2O capacity for the .458 Winchester Magnum.
Norma .458 WM has about 4.5 grains greater gross H2O capacity,
so equivalent loads with that brass may use the same powder charges and ~ 0.100" shorter COL.

So many bullets do well in the .458 WM+
and so many powders too.
So many excellent combinations, too many to shake a stick at.
