Dear Major Khan,
Thank you for another great story.
It was of course spell binding.
I know that I am preaching to the choir when you and many others here read my following rant.
However, it hopefully will be of some use to anyone new to hand loading and hunting larger than deer sized animals.
It is puzzling and a shame that, Winchester released their .458 “Magnum” to the world in such a short cartridge.
In their attempt to drive bullets up near .450 NE Flanged 3.25” velocity, the powder charge they rammed into this stubby brass was seriously compressed.
The chamber pressure was too high.
I suspect this is precisely why your Italian client’s double failed to eject when he opened it.
In double rifles, extractors have a slight advantage, when one insists on using over-pressure ammunition.
In hot weather, chamber pressures spike even higher than they most likely were, at the factories where ammunition is made and tested.
Furthermore, it is a shame that the bullets of yesterday were too soft for animals tougher than N. American deer.
When stout bullets are used, the .458 Winchester is very effective, only loaded to about 1900 fps, on many species (probably not the best ballistics for elephant or hippo on land though).
Fortunately today, rifle powders are such that, the .458 Winchester is now very capable of 2100 fps with 500 grain bullets, without “red line” super high chamber pressure.
Likewise, today’s bonded core bullets are fantastic.
If your client had shot that huge Royal Bengal Tiger in the shoulder with a 450 grain or 500 grain Swift A-Frame bullet, or any of several other present day bonded core bullets, I believe said monster would not have lasted long enough to have attacked you.
Anyway, I’m glad you made it through that bad situation unharmed.
And, thanks again for a wonderful read.
Cheers,
Paul.
