[QUOTE="J E Custom, post: 888179, member: 2736"] Most barrel makers will have there minimum based on the bore and contour. (The bigger the bore the bigger the contour they will require. You can look on there site and based on the bore they will have a minimum contour You cant just say a #5 because barrel makers have different numbers for the same contours as other barrel makers. So you have to decide what barrel maker you want and go from there. There is an unwritten rule of thumb though. Minimum barrel wall thickness at the muzzle for threading or fluting needs to be .200 thousandths. and depth of threads or fluting should not exceed .040. Using this "Rule" A .30 cal barrel would have to be around .700 at the muzzle to be safely threaded or fluted. .650 would be my minimum muzzle diameter for fluting or threading a brake on a thirty caliber.
