Home Forums Hunting & Shooting Express Rifles and Big Bores Only Any Reason for a 458 Lott ?

I have been thinking about rechambering my Rem custom 458 win mag to a lott, is the lott that much better? I have read that it is very simple and you can shoot 458 win mag out of it if you want! I have been looking that you can find lott brass but hard to find 458 win mag brass, is this the wave of the future for the 458?

While I don’t have one, if I were getting another rifle....the Lott would be on a “very” short list of “wanted” rifles. It’s everything that the .458 WM wanted to be! And, as a handloader, you can lightload down to whatever “floats your boat”......but you could “never”, make the .458WM a Lott! JMHO. memtb

yeah thats one reason I bought a cz 458 lott.
I load and shoot mostly hard cast bullets and seldom exceed 2200 fps regardless of bullet weight,
it handles both the 350 grain and 400 grain hard cast bullets ,
but its longer case length, allows use of the longer 500-550 grain hard cast bullets
much better than the 458 win.
a whole lot of guys can,t seem to mentally come to grips with the idea that the vast majority of deer and elk are shot at well under 250 yards,
and a reduced load with cast bullets in a 458 caliber rifle easily handles that limitation



even the hard cast 350 grain gas check bullet at only 1900-2000 fps does impressive damage to any deer or elk, if properly placed

if you get bored... put a cartridge holder stock sleeve on your 458 lott and fill it with the 550 grain bullet hard cast hand loads... it tends to start a few conversations

heres a REMINGTON CUSTOM SHOP 458 WIN rifle

Ranting...You have a PM

If I shoot 458 win mag brass in the lott what will it do to the brass?? nothing ?? or stretch it out?? >> I have a lot of virgin brass in the win mag and as I build up the lott brass

The cases will only stretch if there is too much headspace - and could happen to either 458WM or 458Lott brass. The only problem using 458WM brass may be that you get mis-feeds/jamming thanks to the shorter brass and steeper feeding angle.

So are you saying not to use win mag brass if you rechamber to lott >it can Jam?? not good in a BIG BORE RIFLE!

ITS NOT><>Quit!! Thanks MAU9MM

I like that >> Got it from Down Udder>> and not from a talking head American!!

If you're having feeding problems while using .458 Win mag in a .458 Lott chamber,take it to a gunsmith who then can work on the feeding problem. Jack Lott came up with his .458 Lott to use the .458 Winchester ammo in a pinch.

This is hilarious!

Long load the 458 Win mag and it will out run the Lott

With today's powders, the 458's advertised velocity of 2150 is easily attainable. I'd still with the 458 Winchester

Long load the 458 Win mag and it will out run the Lott>> I like that!! How smart was the Gun Maker?? to make something better and Its not ROCKET SCIENCE!! I have a long Throated CZ 602 375 that I can run with the 375 Weatherby and No pressure problem!>> AT ALL >> But the gun makes try scwish [bleep] into something that should not be and sell it and you have no wiggle room!! but its in the Rag and its better > No its not better >>but keep reading the RAG!

Hard to have increased headspace since the WM and Lott index off the belt. Running too much hot Win Mag ammo thru a Lott could possibly erode the chamber at the mouth of WM brass causing trouble extracting Lott cases.

And a much better throat for cast bullets. Have you ever looked at a chamber drawing for the 458 Win Mag? Throat minimum spec starts about .010 larger diameter than the bullet and is a giant long funnel, not sure how any bullets pass through that without wobbling. Interesting point is that many of the CZ Lotts are factory rechambered Win Mags, at least the rechambering gets rid of the worse part of the Win Mag throat.

A local DG hunter back during the 1950’s, hunted Africa with the 458 Winchester Magnum. He killed all the big stuff with that rifle and had no use for the 460 WBY Magnum. He said he shot clear through a rhinoceros with the 458 and all a 460 WBY would do is hit the ground harder on the other side...

Not owning either what is the benefit in the Lott other than 100-150 fps MV on DG, which is typically shot inside of 125 yards. Another aspect would be that heavy bullets (500 gr.) pushed at moderate velocities typically penetrate as well if not better than the same bullet at a higher velocity. I remember reading a statement from Finn Aagaard saying he shot buffalo, hippo and elephant with 458 WM, 470 Nitro, 500 Nitro and others and saw no real appreciable difference in the performance and effect on killing these DG. He very much liked the 458 WM for its performance, affordability and availability.

I would find a nice un drilled Husqvarna 640, with original trigger and safety and floor plate.
Screw a new barrel on it.
Put a nice peep sight on the rear bridge and barrel band and quality front sight.
Send it to a quality gunsmith and have him spend hours ensuring perfect feeding and extracting.
Put it in a quality stock.

Now you have a perfect rifle for hunting DG.

JMO, you can duplicate or slightly exceed .458 WM velocities....without subjecting the rifle and brass to maximum chamber pressures, that are required with the .458 WM to obtain the desired velocities with the 500 grain bullet! memtb
