Bruce, that .025” MWT only applies to the forward half of the tubes. The first half or rather the first 10” - 12” from the breech is equally, probably more, critical in barrel wall thickness as we should all know is where pressures are extreme. We’ve all seen the pressure curve charts and know the pressures begin to drop off drastically after exiting the chamber. Personally, I pay closer attention to the thickness at the juncture of the chamber and the beginning of the cone.
