When Old Fugly was young and unfouled by the .458 Lott reamer, she was a .458 Winchester Magnum called Warthog.
March 1988 chronographing at 38 degrees F just north of Anchorage, Alaska, when spring had sprung:

Hornady 500-gr RNSN crimped on factory cannelure
W-W Super brass case
F-215 primer
IMR-3031 powder 71.0 grains
5-yard chronograph >>> 2155 fps from 23.6" barrel of 1:14" twist

BC = 0.287 would correct MV to 2169 fps

3-shot group at 100 yards was noted to be 1-1/4". That would be 1.19 MOA.

With that load I killed a moose and a ground squirrel at zero range of 100 yards.

Old Fugly will be slower by a bit with .458 WinMag loads fired in the fouled chamber's extra space for 2.8" brass.
She will need more powder to equal her old results when using 2.8" brass to occupy the extra chamber "dead space."
So sad.
When she was young she was a speedy .458 WinMag.
