Bear this in mind if you intend to measure European barrels with the 16/12 Skeets instrument. Gil


I have the Skeet's 12/16 and the full Stan Baker set for this very reason. The Stan Baker 12/16 head will not measure bores on the larger diameter side of standard 16 bore. Neither set is perfect but between both of them and a set of plug gauges I can pretty much measure anything I need to.
