Only pre-1993 Mini-30s have .308" bores. In 1993 Ruger began using .310" bores so the actions wouldn't take such a beating from .310" surplus ammo.

Yes and No. The pre 93's have a .308 bore with a tapered throat, correct. The reason for the .308 was to use up the junk that Ruger had left over from their failed "XGI". When the junk XGI barrels were all gone they then switched to the proper .310-.311 bore. Had nothing to do with surplus ammo. As a matter of fact Ruger will void your warranty if you use surplus military ammo.
