[QUOTE="J E Custom, post: 1311701, member: 2736"] What you are looking for is a minimum barrel wall thickness after threads are cut (Minor Diameter)of .150 (On cartridges that are less intense you can safely drop to .125 minimum. Some of the older rifles and the light contoured barrels were never intended to have a muzzle brake installed and are already near the minimum wall thickness. The simple formula for calculating this is = Barrel diameter at the muzzle , minus bore diameter, Divided by two. if the minor thread diameter does not reduce the thickness below the minimum, it will be ok. On my web site I have included a brief description of the requirements of different calibers that may help.
