Muzzle brake clearance . I want to brake my 7mm WSM . Bore in brake measures .330 is that to big ?
It will work but will be less effective than if it were .304 diameter. More gas will exit the front of the brake than normal. Depending on the quality of the brake, it will still reduce some of the recoil compared to no brake at all.
Its a PVA shock wave . I bought this as a improvement over the previous brake. I haven't shot it ,so sure hope they exchange it for 6.5 version and my gunsmith will bore that out.

Now on You Tube video a employee of Partriot Valley Arms says "The 30 Cal brake is perfect for the 7mm bore " They've tested it ,I don't want to send it back if its not necessaryWell more people are saying its too big rather than saying it will work. Hope Patriot Valley Arms will exchange it for their 6.5 version. My smith will open it up to ideal size.
