[QUOTE="Toddxusmc, post: 1596827, member: 108726"] I have a 300Win mag that I had a break put on. Iam very disappointed in the way the group opened up. It went from .5/.75 moa to almost 4.3 moa. It’s a difficult thing to figure out as the gunsmith said the poi can change but a group should never be degraded as bad as mine was. It is back with him as I write this. I asked if the bore diameter of the brake was too small (.328) as most run at .338-340 for a .300, to which he answered .328 is plenty and going larger would make the brake less efficient. We will have to see when it gets back if it’s any better. I have a .338 RUM that I had a break put on in the past and that retained the POI as well as the group. I hope he figures the.300 Win out as I don’t have alot of extra cash around to replace the rifle. [/QUOTE]
