Thank you for the input. I did call Weatherby on the subject before making any purchase and bought the brake directly from them. The brake was made specifically for the Mark V and my barrel type with a 1/2 by 28 thread and I did give them all the specific measurements. The diameter at the muzzle is .6125, having just rechecked it after reading your comments. The diameter of the brake at its base is .6150. I will continue on the premise that Weatherby did proper engineering research and that the break itself restores the missing metal, but I will take measurements regularly and watch for signs. Thank you for the input.
