I've started my 3rd Model 10 build, a 6x6.8 or, 6 mm spc. There is a lot of discussion about this "wildcat", but nowhere have I found a discussion on go-no-go gauges. I am assuming 6.8 spc gauges will work, as the 6 mm retains the same case and shoulder dimensions. I don't want to spend $100 on the wrong tools. Can someone verify this?
