458 Win Mag vs 458 Lott....The facts

[Grumpy gumpy]

Kangaroos and possums with a 560gr. bullet? You should have been using your 6.5 Creedmoor for those and saved the big stuff for camels, scrub bulls and such in OZ. LOL

I don’t have a creedmoor, closest to that would be my 25/35 on a martini
My normal wind bag load is a 405 gn pill, they work just as well

Try some 350gr. Speer Hot Cores in your WM. I use those for practice, but I'd bet they'd be great for thin skinned non DG game up to and including moose sized animals?

I’ve got some Speer hollow points that will drop deer and goats with ease, also 600 odd 400gn hard cast coated that is good for practice as well as culling ammo

Thanks! I didn’t see the description included with the photo. That express cartridge must really rock and roll compared to the Lott?

Not really the express was built as a result of lack of powders available in South Africa and the extra space allowed for slower burning powder with less pressure which resulted in less recoil with same speed.

Frederik is correct. I have an Express (long story about how I got it, but in short wanted a 458 WM/Lott in a Brno/CZ action, to build a 450 Rigby. Now a few years later, I can honestly say, I am very satisfied with the Express. Similarly with the Lott and the WM.

It is true, with the lack of powders year ago the Express was created, resulting in less pressure and recoil. This is the beauty of the Express and maybe the Lott over the WM, it gives you that extra room, for a bit more slower burning powder. I am not a reloading expert; but someone explained it once to me (maybe someone can put it on here) the consideration of Load ratio...maybe a discussion for another thread?

@CoElkHunter we did once experiment with the 458 Express and the extra room and loaded it per spec with faster powder. I cannot recall the detail, but it was a 500gr at 2300+ and boy did it have a punch.

Imho, a Lott / WM / Express all have the same felt recoil - it is not a jump between them like from a 375 to a 416 etc. Then again, my 416 Rigby feels to me it has more recoil than my Express... I personally have no issue with either a WM/Lott/Express/Rigby - only with a 460 Weatherby

I’m currently experimenting using VV N550 in the Express instead of the VV N540 I was using.

According to the experts I should get 2250 fps out of my 25” barrel but with what I’m guessing a pleasant recoil.
