Lee Collet Style Crimp Die - .460 S&w Magnum

The Lee Collet Style Crimp Die for .460 S&W Magnum is a specialized reloading tool engineered for handloaders who demand precision and consistency with one of the most powerful commercial cartridges available. Developed for shooters working with the .460 S&W Magnum—a cartridge known for its magnum-level velocity and unforgiving tolerances—this collet-style crimp die solves a problem that has challenged reloaders for years: applying uniform, secure crimps to cartridges that resist traditional methods. Law enforcement training facilities, competitive shooters, and serious handloaders rely on this die to achieve the case neck tension and bullet retention necessary for reliable firearm function and consistent ballistic performance downrange.

The Lee Collet Style Crimp Die incorporates a precision collet mechanism that applies a rifle-style taper crimp to the case neck, a design that eliminates the need for bullets to feature a dedicated crimp groove. This collet-based approach distributes clamping pressure evenly around the case neck, reducing the dimensional variation that often results from roll-crimp or conventional taper-crimp dies. The result is cartridges that chamber reliably and seat with consistent bullet pull, critical for magnums where pressures can exceed 65,000 psi and consistency directly impacts shot-to-shot accuracy and safety margins. Compact at 1.7 x 1.6 x 4.75 inches and weighing just 0.3 lbs, the die threads into any standard reloading press and integrates seamlessly into existing press setups, whether single-stage or progressive platforms.

Handloaders working with .460 S&W Magnum ammunition—including those developing custom loads for precision rifle competition, long-range hunting, or duty applications—will find this crimp die transforms difficult-to-reload cartridges into a manageable, repeatable process. The collet design is particularly advantageous when working with premium brass that may have harder case necks or when loading heavier projectiles that demand superior bullet retention. Compatibility is universal across standard .460 S&W Magnum dies and cartridge components; no special equipment or proprietary components are required beyond standard reloading fundamentals. For shooters serious about ammunition quality and consistency, this specialized die represents a professional-grade solution that pays dividends through improved accuracy, reduced pressure variation, and extended brass case life.
