Rechambered, no.

Rebarreled, possibly depending on the rifle make/model.

7.92 x 57 ? The big question is why would you want to? FMJ practice ammo is readily available and cheap. Hunting ammo is maybe 25% higher than a 30 06. Ballistics for the .308/30 06 are not that much better.

All in all the 8 MM Mauser round is a good hunting choice for most anything, other than small game.

Mostly because we were thinking 8mm was getting hard to find but if it is still around in good numbers might just look harder just wondering does anyone know if any American company's make 8mm

Hornady, Nosler, and Winchester make 8mm Mauser (8x57mm) ammunition. Good USA hunting ammunition can be difficult to find sometimes but it is out there.

The most common (inexpensive) modification of the 8mm Mauser in the USA is almost certainly simply reaming the chamber to 8mm-06. The 8mm-06 ammo can easily be made from 30-06 brass if your friend is a handloader.

A gunsmith would have to check the diameter of the barrel to make sure it really measures .323" and if the action was in good enough condition for the additional power.

All the american .30s are .308 bullet diameter, whereas 7.92x57 (8mm Mauser and others), are .323. There's no way to simply rechamber to a smaller bore unless you want to have the existing barrel reamed, then put a smaller caliber liner in the barrel. I can see the advantages of this if you want a "sleeper" (a factory stock looking rifle that performs much better by having a match quality custom barrel liner). Otherwise it's not really practical since by the time you buy a barrel liner, reaming the old barrel to the larger liner inside diameter for the liner, then installing the liner/& anchoring it, you'll usually be out at least twice what you would have in a barrel right off the bat.

I have a vz24 mauser. I usually buy ppu fmj for target practice and Remington for hunting. I would feel very comfortable using it for whitetail or hogs. Ide leave it how it is
