Case Gauges & Chamber Checkers
Most match malfunctions trace back to ammo, not the gun — a bulged, deformed, or over-length case that won't fully chamber. Dropping every round through a case gauge before a match catches those failures on your bench instead of on the clock. Ben Stoeger Pro Shop stocks single-caliber, multi-caliber, and high-capacity gauges from Shockbottle, DAA, EGW, Dillon, and Lyman.
Which Gauge Do You Need?
- Single-caliber gauges — the simplest, most affordable option if you only reload one caliber
- Multi-caliber gauges — DAA's 4-pocket gauge covers 9mm, .38 Super, .40 S&W, and .45 ACP in one compact tool that fits on a keychain — ideal if you reload multiple calibers or want a single range-bag gauge
- 20-pocket gauges — DAA's 20-pocket gauge cuts case-gauging time by more than half compared to a single gauge, letting you drop-test a full box of ammo in one pass
- The Hundo (100-round) — Shockbottle's 100-hole gauge is the fastest way to check a full box of match ammo, doubling as a flip-tray that inverts directly into a 100-round ammo box, bullet-down and ready for the range
