I haven't shot 220gr out of a .308 yet, but i would think a little testing to make sure it is stabilized out to your max working distance would be called for. IIRC most .308s are 1/12 twist.....which may or may not stabilize the 220gr RN....just some food for thought. that is why most 30-06 are 1/10 twist...so they can reliably stabilize the heavier bullets. the military went with a 1/11.25 twist to stabiliz the 175gr SMK....which i would think is close to the minimum twist required for the 220gr RN.
