While in the process of building a benchtop barrel thickness gauge it dawned on me that this idea could be used for measuring chambers with some changes. Here is something I quickly threw together, it is easy to see when the forcing cones are reached, no guess work. Laying the barrels on a flat surface and sliding the tool into the chamber is simple. No need to have a real rigid probe as you are just looking for the change of thickness, what do you guys think?? Yes I know the 3” mark is in the wrong place.
