Hosford and co. barrel wall thickness gauge

[Bob Jurewicz]

Marcus,
The Skeets Bore Gauge and the Hosford Wall Thickness Gauge have distinctly different function. The Skeets will give you inside bore diameter. Hosford will tell you how thick the barrel walls are. In my opinion both very important to determine condition of a set of barrels.

Thanks Bob. My original thought was that the Skeet's used in conjunction with a caliper would allow one to calculate the wall thickness. I guess that idea is flawed in more than one way. It assumes the barrel is perfectly concentric and does not take into account any area where a repair has been done (dent removal?) causing a possible thin spot.

Cheers
