[QUOTE="J E Custom, post: 1415699, member: 2736"] This is the reason I am anal about barrel wall thickness and brake diameter. Even though the pressure at the muzzle is less than Peak pressure, brake have been known to fail and barrels have split when the barrel wall thickness is less than needed. The engineered minimum thickness(Measured from the grove to the minor diameter of the thread) Is .137. I like to round off to the safer side and use .150 (.013 thicker) There has been lots of discussions about this and failures continue to happen. It is hard for me to believe it happens with a factory installed brake, but it sometimes does. Sorry it happened to you but glad you came away unscathed. Sometimes people want looks over function and cut a brake down below a safe size to match barrel diameter. This reduces web strength to unsafe thicknesses. J E CUSTOM [/QUOTE]
