The 375 H&H and 458 Win Mag! 

I read an article that said Winchester originally loaded this round with a 510gr solid @2150fps with 5,670FT/LBS of muzzle energy and the compressed gunpowder would clump together under certain conditions which lead to mr Lott getting mauled by a cape buffalo because his 458win ammo malfunctioned and he created the 458 Lott because of it, now because of modren gun powder and better ammo technology the 458 win mag is a monster with no ammo clumping problems anymore.

I could listen to you talk all day. Thank you Ron!

American ingenuity, incomparable National intellect when unbridled. Thanks for sharing!!

Let's see more on the .458 Win Mag.

My understanding was the 458 had to have the same energy as the 416 Rigby. When you load the Rigby to the same pressure levels as the 458 you can push a 400 grain bullet to 2600fps.

I have two friends that has 458 Lots in TC contenders

A fella took a .458 Win Mag to Africa after Cape Buffalo. While recovering in the hospital, he mused about a more powerful cartridge. His name was Jack Lott.

I've shoulder fired a 50BMG and would do it again rather than shoot that 458. Cause it's a 30 pound rifle, not a 9 pound rifle.

And they compressed the power charge so much it caused clumping problems in hot environments (with then available powders).

Sir, I am from India can you please share some idea which rifle is better winchester model 70 375 H&H magnum or westly richard's 375 magnum... Thank you

Well, at the time, Winchester was lying. It didn't perform as well as the box said. They had serious problems with powder clumpin lack of velocity. At the time it just didn't live up to the hype.Cause if it had the 458 Lott would never have been produced.

I'd rather have the 458 Lott 😅

* Should of just adopted the .450 Watts.

I will stick to my 416 rigby over the 458
