Barrel Chamfering Plug Gauge

[Mark Terry]

Does anyone have any experience with these?

I have both .44 and .45 variations.

Barrel throat diameters for my Ruger 44 spec is as the tool indicates it should be but a Redhawk and a Blackhawks (both SS) are way larger that the tool indicates they should be.

If the f/c is not the same angle as the plug, it can show that it is too deep when in reality it is not.
