Most are 1:12, but Savage 308 rifles are 1:10, there may be others.

A standard twist .308 or .30-06 barrel wil fire anything from 140 to 220 grains.

It will fire it, yeah, but it may not stabilize properly. The 1:12 should work fine up to 180 grains, IE most commercial ammo. For heavier, you really need 1:10.
