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

Sir Indy,
You have chair # 22 at the Square Table.
Congratulations.
Keep up the good work.
Doing good has no end.

My concluding words at the other forum today, where it will fall on deaf eyes most likely:
****************************************************************************************************************************************
Nowadays, If one can handload, one can get within 50 fps of the .458 Lott with 500-grainers, and do it at lower pressure
(60,000 psi instead of 62,500 psi) and with COL of 3.340" instead of 3.600".
It is all about throat.
If one uses same higher pressure and same longer COL as the .458 Lott, with bullets long enough to do that in the .458 WinMag,
one can outperform the SAAMI .458 Lott (2.8" case) with the non-SAAMI .458 Winchester Magnum (2.5" case).
It is all in the throat.
Physics cannot be denied.

The .458 Lott Protective Association is all about commercialism.
I recommend reaming your SAAMI .458 Lott with a SAAMI .458 Winchester Magnum reamer to correct the throat.
Then it will be just like the .458 Lott that Jack Built.
Then it will be on par with the .458 Winchester Magnum.
Any load safe in the .458 WinMag will then be safe in your .458Lott like Jack Built.

If the short-and-tight-throated SAAMI .458 Lott at 3.600" COL and 62,500 psi will do 2300 fps with a 500-grainer,
then the long-leade-zero-parallel-sided-free-bore-throated SAAMI .458 WinMag at 3.340" COL and 60,000 psi will do 2250 fps with same 500-grainer.
Do I hear an "amen?"

Fairly humorless bunch over there.
