Zastava 458 questions

Why not? said:
Aside from not needing the Mauser bolt face to be altered, would that be another reason for the .425 Westley Richards having a rebated rim, to reduce bolt thrust?

Amen Bro. My first 458 Winchester was built on a VZ24 by Fred Breitwiser in Kitchener, Ontario. It was very handy, but a bit too light, especially with 75 gr of Ball C2 and 500 gr bullets.

It ended up in the NWT, Yellowknife iirc, shortly after I came to Whitehorse, where it almost immediately accounted for a huge bison.

The second one was built by Bevan King and weighs close to ten pounds empty. :)

Tough to say as I’m guessing, I suspect it would be reduced a bit, due to the reduced area inside the case at the head, despite the base of the case being larger in diameter. Not sure if zee Germans would have planned on that too during the design? Little eluded them though, they engineered things pretty darn thoroughly.

I’m with you on the light rifles and 500gr bullets entirely. And the Zastava has one of the lightest .458 barrels made.
 
I have an Appleby 425 express thats about 80% built..... Oberndorf 98 action...need to get the feed rails done....

With the weight of the M70 you would have an utterly savage recoiler with it as a .458 Lott. I shoot a handful of big stuff and would politely decline shooting a Lotted Zastava, likely by answering with a question and then changing the subject.

So, maybe this dream is a nightmare in waiting?

Well, give it a try. If it's too much just repeat the mantra "harden the f- up, harden the f- up" to yourself until you stop flinching. If that doesn't work install a recoil dampener or a brake and deprogram your flinch on a rimfire lol!

I have one in .458 and .375. The 375 is my go to hunting rifle. The .458 is occasionally fun to to shoot, but kicks like a mule. I've never had feeding issues with either. I've always wanted to open the .458 win to a .458 Lott, but have neither found the reamer, nor am I certain it would work easily....

Or, you could sell your Model 70, and get one all ready to go.

Don't know the guy, but I think you would have a much easier time selling a factory RSM than a rechambered Zastava when that day comes.

I have and shoot a #1 in .458 WM, Many times when I have it at the range some guy will ask me about it and then immediately say " why dont you rechamber it to .458 Lott " I them put 5 rounds of my 500 grain hand loads on the bench and say " go ahead give it a try" None of them shoot all five, but they do comment on its recoil, as they walk away I ask them if I should still re chamber it, not one has said yes.
 
The biggest issue with the .458wm M70 is it’s not a .458Lott. Want an interesting read, look up the story why Jack Lott invented the .458Lott. All because of a near death experience with a .458wm that failed to penetrate the head of a charging buffalo. There is a major flaw with that cartridge and it’s all because of trying to make a shorter case preform like a bigger case. Although there is no documented incidents with the .375/.416ruger. The same flaw could happen as again they’re trying to make a smaller casing preform like a bigger casing. Compressed loads like these cartridges are likely to have can result in powder clumping especially so with ball powder. If the powder clumps, it can result in velocities significantly less than advertised velocities. Sometimes just 1000fps. So Jack Lott made the bigger case of the .458 Lott to prevent the powder from clumping and gained an extra couple 100fps. The .458 Lott can also fire .458wm which was a big deal at the time since the .458 Lott was a wildcat cartridge for many years. All that said, I’d still buy a .458wm if one came up for sale at the right time. I just can’t say no to a big bore cartridge.
 
the 458 win magnum as no flaw with today powder. you should read some comments on the 458 win mag from Finn Aagaard Don Heath or even Jack Lott. he created the 458 lott because of the powder not the rifle (winchester model 70) nor the caliber ...

Very true, with modern bullets and powders it can do the job it was designed to do without issues. It’s similar to how some disparage the .416 Remington because there were a few pressure issues in extremely hot climates very early on, but again it is wonderful with current powders. Historical accounts are very useful, but changes in technology have to be taken into account before making judgments on the current usefulness of these cartridges.

That being said I don’t own either, but that’s only because there are so many good choices these days and I ended up going another route.
