"Proof" load - 6.8mm SPC?

[Erick Gelhaus]

Does anyone know the specs on the "proof" loads for the 6.8mm SPC? I was speaking to a firearms manf this AM and the subject came up. I asked for their specs and they said it was proprietary.

Any info?

In advance, thanks.

I didn’t know one existed. Not that there shouldn’t be one.

What manufacturers are MP testing 6.8 barrels?

Is it naïve to think that it would also be 70 ksi?

I'm more interested in who proofs the bolts. So far as I know, no one does.

I have the SAMMI specs and 2 reamer charts for the 6.8 if anyone is interested in them.
Lemme know
