Lee Collet Style Crimp Die - .500 S&w Magnum

The Lee Collet Style Crimp Die for .500 S&W Magnum (SKU 90931) is purpose-built for handloaders working with one of the most powerful commercial magnum revolver cartridges available. This die addresses a critical reloading challenge: the .500 S&W Magnum's unique case geometry and high-pressure demands require precise crimp control that standard dies struggle to deliver consistently. Whether you're a competitive shooter, hunting enthusiast, or precision-focused reloader, this Lee product solves the crimp problem that has frustrated serious .500 S&W handloaders for years.

The collet-based crimp mechanism is the standout feature of this die—it applies a rifle-style crimp rather than a traditional roll crimp, which is essential for magnum revolver rounds operating at extreme pressures. Unlike conventional dies that require bullets with a crimp groove to function properly, the collet design grips the case mouth uniformly without necessitating groove-equipped bullets, giving you greater bullet selection flexibility. This collet approach dramatically improves consistency from round to round, reducing the variability that often plagues magnum handloads. The die's compact footprint (1.95 x 1.55 x 4.8 inches) and light weight (0.25 lbs) make it an efficient addition to any progressive or single-stage press setup.

Serious .500 S&W Magnum reloaders—particularly those pushing for accuracy and reliability in hunting or long-range revolver applications—will appreciate how this die transforms a notoriously difficult crimping task into a repeatable, controllable process. Installation follows standard Lee die threading (7/8"-14 TPI), making it compatible with virtually all progressive and single-stage reloading presses. For hunters relying on the .500 S&W's raw stopping power or competitors demanding sub-group consistency, this collet crimp die is an investment that directly translates to tighter groups and more reliable ignition under magnum conditions.
