    I just made myself a barrel wall thickness gauge similar to the Manson one. Anyone have a point of view on what the proper technique is to use one like this? My trials so far indicate that using it vertically and carefully finessing the barrel between the anvil and the indicator probe seems to work, but I don't have a control to verify the measurements. Any thoughts?

    Measure the bore diameter with a bore micrometer and the outside diameter at the same spot with a micrometer. Then subtract the smaller number from the larger number and divide by 2.
