Anyone have a quick measurement of Muzzle diameter of the Frontier rifle target grey in 358 winchester?

Thanks,
Andy

most barrelmakers want .150" on each side of the bore at the muzzle for safety.

.610 - .308 = .302 or .151 on each side of the bore

if their machining tolerances hold true, the .358 barrel should be around .658" at the minimum, or larger for exactly .150 on each side.
