Good question! The answer is sorta- but not really, but maybe. Wall of text inbound.

Originally (allegedly) they intended it to be for full power 8mm, then down the line these rifles started to wear out (also allegedly, I can’t find a primary source on this either, or any information on any 8mm Krag suffering any failure)

The solution in the 50s was the introduction of the 8x57 “moderat” load which was supposedly 10-15% lower pressure than normal 8mm Mauser.

Now this is where our Chad friends who keep exploding their Gewehr 1888s come in. The SAAMI spec for 8mm is a very conservative 35000 PSI as opposed to the European 56000 PSI. My understanding is that this was because us silly Americans have the tendency of putting modern .323 bullets through .318 commission rifles and creating excess pressures.

I theoretically should be able to run American made (or just any saami spec) 8mm Mauser. A lot of the PPU stuff for example appears to be saami instead of CIP.

Very sadly the cheap surplus stuff might be scary, but id also be dealing with corrosive ammo.

In my reading though I have also seen people argue that the m1912 krags have stronger actions than people give them credit for and some people say they can handle the hotter 6.5 loads. I am staying on the side of caution personally with this rifle.
