Product Overview

The Lee Primer Pocket Gauge Set is a no-nonsense way to keep your brass honest. With dedicated small and large GO/NO-GO gauges, it quickly tells you whether a primer pocket is still within SAAMI spec, crimped too tight, or flogged out and unsafe. Drop the GO end in – if it won’t seat, you know the crimp needs sorting. If it feels sloppy, flip to the NO-GO side; if that reaches the bottom, that case goes in the scrap bucket.

Built for handgun and rifle reloaders who care about reliability more than theory, this compact gauge set slips straight into your range box or bench drawer and is ready whenever you’re processing a batch of brass. Pair it with a Ram Swage or APP Swage and you’ve got a fast, repeatable system for turning mixed, once-fired brass into match-ready ammo that holds primers tight and runs clean in Aussie conditions.
