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

Good show Sir Jerry.
For Sir Roo, take note.
If you want light rifle carry, here is as light as I like to go in a .458 WM:







Marcella is an M70 .416 RemMag action re-barreled to .458 WM
with a No. 4 sporter contour McGowen of true .458" groove,
cut down from 26" to 23" at the muzzle end of the barrel blank.
It is almost as fast as a 25" Shilen which has closer to 0.459" groove.
400-grainers at +2500 fps was no problemo in either barrel, with AA-2230.
This will be my deer rifle this year, with the 404-gr. Shock Hammer at 3.480" COL.
But I will add the weight of a scope and more:



The 400-gr GSC HV handload was at + 2500 fps from the Shilen.
Same rifle did about 2350 fps with the Buffalo Bore factory loaded 400-gr TSX.
Both killed deer with results similar to Sir Jerry's illustration.

This one needs some accessories added to it for extra weight:



Same as the CIP homologated .45-70 Elko Magnum, with Starline brass for .45-2.6" it is 2 grains H2O bigger than the .458 WM.
The slow twist comes from re-chambering a .45-70 Gov't.,
and note that Ruger makes those with the same groove diameter as their faster-twist .458 WM barrels,
even though SAAMI minimum is 0.456" for .45-70 Gov't.
