Lyman 7705201 Pro Single Ammo Checker .300 Blackout Case Gauge

The Lyman 7705201 Pro Single Ammo Checker delivers precision case length verification for .300 Blackout ammunition, ensuring consistent chambering and optimal performance. This machined steel gauge eliminates guesswork in ammunition preparation, providing reloaders with a reliable method to verify proper case dimensions before firing.

What Makes This Different

Unlike basic go/no-go gauges, the Lyman Pro Single Ammo Checker features precision-machined chamber dimensions that match SAAMI specifications exactly.
