Not so good for smaller calibers
Bought this to to test a Ruger American Ranch Gen II in 5.56 that was having misfires with Hornady match ammo. Gauge is easy to use, but the Ruger's bolt face is so tight that the extractor has to be forced out to get the gauge inserted flush. Took multiple attempts to get an accurate reading. Larger calibers shouldn't be a problem.
