Do I have a Go - NO GO Issue ?

got to remember he is using virgin brass and as such it could be short to start with.

You may be right earl but nowhere does he say virgin. He said new. some people size new brass like myself.

He doesn't need a comparator...he has the barrel. All he has to do is what I said. I think the gauges are wrong.

Hopefully he has a set of dial calipers and knows how to use them...or a depth mic.
