BROWNELLS SHOTGUN CHAMBER GAUGE

The Brownells Shotgun Chamber Gauge is a specialized diagnostic tool designed to help gunsmiths evaluate shotgun chamber dimensions and identify obsolete chamber lengths that can negatively impact performance with modern shotshell ammunition. Developed around the chambering concepts championed by renowned gunsmith Ralph Walker, these gauges provide a fast and reliable method for inspecting chamber length and verifying chamber modifications after reaming work is completed.

Many older shotguns were built around ammunition standards that differ from today's star-crimped plastic shotshells. Short chambers and inadequate forcing cones can contribute to increased recoil, elevated pressures, deformed shot, damaged hulls, and inconsistent patterns. The Shotgun Chamber Gauge helps identify these issues and allows gunsmiths to verify that chamber and forcing cone work has been completed correctly, helping improve overall shotgun performance.
