MFS 30-06 safe to use with M1s?

[Rick the Librarian]

I had a friend of mine obtain some MFS-headstamped 30-06 the other days and he wondered if it is safe to use in his M1. I've never heard of the stuff. Any opinions (hopefully educated!)?

TIA

It is from Hungary or Nepal. Cannot tell you if it is corrosive. I have no other info on it.

Either had to seat deep or have them tip in the feed way, so used them for other firearms. Hungry is correct as the source of the ammunition.
OK so I stand corrected about the country of orgin. I picked up this stuff for about .11 cents a round at a brick of 1000 rds. Initially I used it on my Garand, and people reported down the line that the noise was way excessive, and in the Garand I began to experience case seperations or the primers backing out of the cartridge and fouling up the trigger mechanism.

I shifted use to only one bolt action rifle that can handle the excessive load: My M-1917 Eddystone. Shoots this ammo like a tack driver. But at least one round fully seperated at the base and sprayed my face with molten brass. Good thing I was wearing googles. Another round had no powder and the round bearly left the muzzle to fall short down range.

I don't have much left, but I can not imagine the stuff improving with age. Probably better off destroying it before someone in my family gets ahold of it long after I am gone.
