I think when those mausers were converted, it was for 7.62 CETME (or something like that) which was a lower pressure than the NATO stuff.
I believe the CETME round is about 45,000 psi = 37,000 cup which is in the same category as the original 7x57 mauser pressures;
I think the 7.62 NATO/308 Winchester is in the 60,000 psi = 52,000 cup, which is certainly to high for one of those Spanish mauser actions,
it might not blow up, but high pressure use, could set the lugs back or stretch the action and/or chamber.
Someone who knows for sure will chime in.
