[QUOTE="Chase723, post: 1596967, member: 21524"] Todd, if your groups opened up to 4MOA I would seriously wonder a couple things 1) What class are the tolerances of your threads on your barrel and brake? 2) Is you bore concentric in your barrel? 3) Is the hole in the brake concentric to the middle of the brake? .328 is pretty tight. That’s only 10 thousandths on each side. If your threads are sloppy and your bore or the hole in the brake aren’t concentric then 10 thou can get eaten up pretty quick and your bullet could be contacting the brake. The difference in effectiveness of the brake between .328 and .340 is negligible. Even at .400 it wouldn’t be much different. [/QUOTE]
