[QUOTE="J E Custom, post: 1446707, member: 2736"] You are correct, If you use a brake with a bore larger than the bullet diameter + .020, It will not be as effective. It will still reduce recoil but not as good. Ideally, the bore size of the brake needs to be a minimum of .015 larger than the bullet. You can go as little as .010 larger but you run the risk of a bullet strike unless everything is perfectly centered on the bore. The best efficiency of the bore hole in the brake measured during test was .015 to .025 larger than the bore. anything less gained no measurable recoil reduction, and up to .025 it remained at maximum efficiency. Beyond a .025 larger bore hole the recoil reduction degraded rapidly from its best size (.015 to .025). I will caution anyone from switching brakes back and forth because of the possibility of placing the wrong brake with a smaller bore size on the rifle. (I know it sounds like know one would do that) but I have repaired many rifles and brakes that have had that happen. Besides bullet strikes being bad for accuracy, they can also be dangerous and sometimes cause the muzzle brake to join the bullet and leave the barrel at the same time. J E CUSTOM [/QUOTE]
