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

Ah ha, so that is LabRadar MV. Needs no 5-yard correction to MV.

Sorry, Sir Larry, you did not break 2600 fps MV with your .458 Lott. The .458 WinMag+ did it with a starting load, haha.
No need for such speed. Lesser speed do kill.
Your .458 WinMag build recipes are much more interesting than circumcising your .458 Lott to 22".
Just my take.
To each his own madness makes the world go round, haha.

I am interested in squib loads for the .458 WM, something to imitate function like its ancestors: .22 Short Rimfire and .44 WCF.
For starting reference, the .44 WCF Cowboy Load with Trail Boss:



And a good load test snagged from an internet video, factory smokeless of recent make .44 WCF,
still going after 149 years , just like the .45-70 G and the .45 LC:



Trail Boss loads for the .458 WinMag:



A barely subsonic 400-gr Lee Hollow Base FN of 20:1 alloy, PC-painted, might turn the .458 WM into a real rabbit rifle !
There may yet be a good use for the soft 400-gr Speers, subsonic and suppressed, for small game.

Reminds me how the US government screwed up a trial of the .458 1.3" belted with 500gr FMJ bullets at 1100 fps,
for sentry elimination at 100 yards, in Vietnam.
What a Rube Goldberg contraption they created !
14 pounds and long barrel, they built a couple and scrapped the project with no bona fide field use.
Silencer looked like a watercooled machinegun barrel shroud from WW1.
Could have been done with a short-barreled, faster twist .458 WM 2.5" and a standard silencer.
Could have been shorter overall length, and 4 pounds lighter.
Might have been practical then.
