Lyman 7833000 Ammo Checker Handgun Cartridge Case Gauge .380-45 ACP

The Lyman 7833000 Ammo Checker provides instant verification of handgun cartridge dimensions across seven popular calibers from .380 ACP to .45 ACP. This precision-machined gauge eliminates guesswork in ammunition inspection, ensuring proper chambering and preventing costly misfires at the range or in critical situations.

What Makes This Different

Unlike basic go/no-go gauges that check only one caliber, this multi-caliber checker handles seven common handgun cartridges in a single compact tool. Each chamber is machined to SAAMI specifications with tolerances held to ±0.001 inches. The anodized aluminum construction resists corrosion while maintaining the precise dimensions required for accurate case length and diameter verification.

Key Features

• Seven caliber chambers: .380 ACP, 9mm Luger, .38 Special, .357 Magnum, .40 S&W, .44 Magnum, and .45 ACP
• SAAMI specification chambers machined to ±0.001-inch tolerance
• Hard anodized aluminum construction for durability and corrosion resistance
• Compact 4.5-inch length fits easily in range bags or reloading benches
• Laser-engraved caliber markings that won't wear off with use
• Beveled chamber entries for smooth cartridge insertion
• Matte finish reduces glare under bright lighting conditions

Reloaders rely on this checker to verify case length after trimming and confirm proper sizing after resizing operations. Competition shooters use it to ensure ammunition meets match requirements before heading to the line. The tool quickly identifies cases that are too long, improperly sized, or have other dimensional issues that could cause feeding problems or unsafe pressure conditions.
