Lee Trimmer Gauge .500sw -

The Lee Trimmer Gauge .500sw is a precision reloading accessory designed for shooters and reloaders who demand consistency in case preparation. Built by Lee Precision, a trusted name in ammunition reloading for decades, this trimmer gauge ensures that every .500 Smith & Wesson case is cut to exact specifications before loading. Whether you're a competitive shooter, hunter, or precision rifle enthusiast, maintaining uniform case length directly impacts accuracy, velocity consistency, and firearm safety during firing.

This trimmer gauge works in tandem with Lee's case trimming systems to verify that each .500sw case meets maximum length specifications. The compact design—measuring 3.65 x 0.55 x 4.95 inches and weighing just 0.07 lbs—makes it portable and easy to integrate into any reloading bench setup. The gauge functions as a go/no-go tool, allowing you to quickly identify cases that require trimming or have been trimmed correctly, eliminating guesswork and reducing the risk of oversized cases that can cause excessive pressure or extraction issues.

Reloaders working with large-format handgun cartridges like the .500 Smith & Wesson will find this gauge indispensable for batch reloading. Its precision engineering ensures repeatability across multiple reloading sessions, which is critical when preparing ammunition for heavy-hitting magnum revolvers where case integrity directly affects performance and shooter safety. The Lee Trimmer Gauge .500sw is an essential quality-control checkpoint for anyone serious about handload consistency and ammunition longevity.
