I don't know what the heat treating process for an FN is, but if that would be a Mauser I would say the heat treating was done incorrectly. I have seen a few Mauser re-barrels that had "accident" loads run through them and there was evidence of bolt lug and receiver lug set back before cracking

Wish I knew more about the FN, it could have been too brittle. I have seen pictures of M70 cracked lugs due to the short magnums, so heck if I know.
