There's rifling in Mini-14's???? Most of the ones I've shot acted like smoothbores..... 
1x12" I believe-like the M16A1.

I think there was also a run of 1/10 rifles...color me dizzy.
None of these rifles should "tumble" bullets in the air, but that can happen with long bullets in 1/12 barrels. Almost all (all?) spitzer-type bullets will tumble once they land in something more dense than air (like animal flesh), since the bullet is stern-heavy and trys to reverse itself after it becomes unstable. The wounding potential of USGI ball ammo comes from the fact that it usually breaks at the cannelure and/or breaks into many pieces (depending on velocity at target impact), but this is a product of bullet velocity and bullet design, not a result of 1/12 vs 1/7 or other rifling rate issues.
