.200 Line Measuring Tool Kit
These little gizmos make measuring the .200 line a fast, repeatable exercise. They hold the case by the base and have a slot at the 200 line for calipers so you get a repeatable measurement.
The 200 line on brass refers to the spot on the body of a cartridge commonly measured to evaluate sizing dies, monitor pressures and eliminate "clickers", the annoying hiccup that occurs when brass isn't sized properly. Usually this symptom is fixed with a different FL die (possibly small base or custom) or a ring die.
Available to fit nearly every family of cases. This kit includes them all, sized to be a couple thosandths inch larger than case diameter. Available soon indiviidually. (Patent Pending)

I used this tool to help out a friend that was having clickers with a Custom 6BR rifle. Following the instructions it was immediately evident that the .200 line was not being properly sized. A proper die cured the problem.
