Hornady 380723 Cartridge Case Gauge .284 Win 7mm PRC Precision Tool

The Hornady 380723 Cartridge Case Gauge provides precision measurement and quality control for .284 Winchester and 7mm PRC cartridges. This essential reloading tool ensures consistent case dimensions and proper chamber fit for enhanced accuracy and safety.

What Makes This Different

Unlike generic go/no-go gauges, this cartridge case gauge features chamber-spec dimensions machined to SAAMI tolerances. The gauge allows reloaders to verify case length, shoulder position, and overall cartridge dimensions before firing. Precision-ground steel construction maintains dimensional accuracy across thousands of measurements, eliminating guesswork in case preparation.

Key Features

• Dual caliber compatibility: .284 Winchester and 7mm PRC cartridges
• SAAMI specification chamber dimensions for accurate measurement
• Hardened steel construction with precision-ground surfaces
• Identifies oversize cases that won't chamber properly
• Compact design fits standard reloading bench setups
• Laser-etched caliber markings for quick identification
• Compatible with both factory and handloaded ammunition

This gauge proves invaluable during case preparation, allowing reloaders to sort brass by dimensional consistency and identify cases requiring trimming or resizing. Competition shooters rely on these measurements to maintain ammunition uniformity, while hunters benefit from verified cartridge dimensions that ensure reliable feeding and extraction. The tool works equally well with new brass, once-fired cases, and heavily reloaded components.
