WAO! That's all I am saying!All of mine at 7s, never seen a downside to it. 8s will shoot a lot of things fine (like 200gn Makers), but just like Wedgy said seems like with monos making big strides twists keep getting faster and faster to run them.
My 8.6 BLK barrels are 3 twists, going to run 350gn monos out them.
