[QUOTE="Fiftydriver, post: 842396, member: 10"] For my Painkiller muzzle brakes I tell customers and other smiths to ream them a minimum of 20 thou over bullet diameter. If the threads are machined true, this is plenty of room but I never recommend anything tighter then this. Your situation confuses me somewhat. Was your brake supposed to be set up already for a 30 cal bore? If it was reamed by your smith, how could the center partition passage be tighter then the others? ALWAYS check that any brake is reamed properly before shooting, that goes for ALL port passages. This is one reason why I do not ship prereamed brakes, its better to make the smith or machinest ream the brakes to the recommended diameter then to have them ASSUME you did it for them. If the bore is reamed 20 thou over bullet diameter and your still hitting some portion of the brake, something is seriously out of alignment but hitting in the center of the brake makes no sense at all. I suspect the brake has not been reamed..... [/QUOTE]
