I LOVE the fast shooting barrels. Especially on my bull barrel bolt rifles. I prefer the 1 in 10 twist rate and faster on my .308's. It stabilizes the heavier bullets for longer range. The 169gr is great out to 600yds but prefer the 175gr pills for longer than that.. They stabilize the heavier rounds for subsonic also..
As for this barrel, I have never used this specific one I don't think but do like the 1/7 on AR at times..
