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

Ganyana reported zeroing his .458 Lott 450-gr TSX bullet (2380 fps) for 50 meters.
Then his single, hardcast lead roundball (.460" diameter, 150 grains) load was spot on at 20 meters.
800 fps from 12 grains of South African powder called MS200.
Higher velocity and the ball skids in rifling and accuracy goes south.
"25 yard load at best."
Touted as a small game load, feeds well from magazine too.
"To make up one of these rounds, resize the case -- bell the mouth slightly; prime; tip in the powder;
and seat the ball tightly by finger pressure alone. The case does not need resizing after shooting with such light powder charges,
and a simple `Lee Loader' de-capping punch and a primer seating base is all the equipment required for endless fun and practice."

I bet even a .458 Winchester Magnum could be used for that.





My first screw up here was in using three of the .451" balls with a gas check under them in a .458 WinMag with 18.5 grains of BLUE DOT.



Those were soft swaged lead balls of too small diameter.

Hardcast roundball of 0.460" diameter at 800 fps seems to be the recipe for accuracy,
for head shots on guineafowl and squirrels and such.
The Garmin XERO will make that easier to arrive at.
