EGW
The EGW .45 ACP 7-Hole Cartridge Checker is a precision measuring tool designed for reloaders and shooters who demand ammo reliability. Whether you're verifying factory ammunition before a match or inspecting your own handloads before they hit the range, this checker lets you confirm that rounds meet chamber specifications—catching out-of-spec cases that could cause feeding problems, jams, or misfires before they become safety issues.
Built from solid 6061 T6 aircraft-grade aluminum and machined with actual Clymer reamers, this .45 ACP chamber checker replicates the geometry of a real chamber, giving you genuine spec verification rather than generic estimates. The seven-hole design accommodates multiple cartridges for efficient batch checking. It measures both minimum case diameter and maximum overall length, the two critical dimensions that determine whether a round will chamber safely and feed reliably.
The anodized matte black finish resists wear and corrosion, standing up to frequent use in the reloading room or on the range. It's a straightforward, no-battery tool—the kind of precision instrument that pays dividends in confidence and consistency, especially if you're running tight tolerances or working up loads for a demanding firearm.
| Caliber | .45 ACP |
| Material | 6061 T6 Aircraft-Grade Aluminum |
| Finish | Anodized Matte Black |
| Reamer Type | Clymer |
| Holes | 7 |
| Measurements | Minimum case diameter and maximum overall length |
A cartridge checker catches spec violations before they become range problems or worse. It replicates your actual chamber and identifies rounds that won't feed, won't seat properly, or might cause pressure issues—saving you downtime, parts, and safety headaches.
Yes. The checker works with any .45 ACP round, factory or handloaded, to verify it meets chamber specifications before shooting.
Clymer reamers are the industry standard for defining accurate chamber specifications. Using actual reamers ensures this checker replicates a real .45 ACP chamber rather than a generic approximation.
The seven holes let you check up to seven cartridges at once for efficient batch verification of your ammunition before you reload or shoot.
