@ur12vman I guess I stand corrected, I know my Issue rifle is 5.56 NATO in a 1:7 twist rate, and most .223's I've seen are a 1:9 twist rate. You know more than I do but most all surplus ammo is "de-milled" I know the military loves hot powder charges.
@feartone1 Yes Brian you do. I was Rob the bass player.
