Hornady OAL Guage

[activereality]

Hey all. Wondered if I could ask a favor. Can anyone give me the rough diameters for the The Lock-N-Load O.A.L. Gauge main tube (red) and the silver portion (where the thumb screw is).

Measurements from either the Straight or the curved models will work fine.

note: not asking for measurement for a comparator - this is the tool used to 'find your lands'.

thanks for any help!!
