Lyman’s E-ZEE Case Gauges have proven to be a real time saver for reloaders and are available for most common calibers. The precisely machined metal “No-Go” gauge is cut to SAAMI maximum allowable case length. If a case fails to pass through the gauge it needs to be trimmed. For 2019 Lyman is now offering two specialized E-ZEE Case Gauges designed for Cowboy Action shooters and those reloading for the wide range of MSR calibers. These convenient gauges are offered for the following calibers: - MSR: 223/5.56 224 Valkyrie 6.5 Grendel 6.5 Creedmoor 6.8 SPC 300 Blackout 308 Win/7.62 7.62x39 9mm 450 Bushmas- ter 458SOCOM 50 Beowulf plus 2.260” max. cartridge OAL
