Mine is overbored at the factory (should still have chrome lining, then, I would think), with a diameter of .742. That appears, from this SAAMI sketch (2nd page) to fall within the boundaries of standard 12ga.:

That would seem to suggest I'm *safe* to shoot slugs, but I probably won't have as good accuracy.
Crazy what Mossberg did/does, making a .770 barrel! I learn something new everyday!
