Lee Classic Bullet Size Kit .460"

The Lee Classic Bullet Size Kit .460" is a precision reloading tool designed for handloaders who cast their own projectiles and demand repeatability in ammunition assembly. This sizing kit serves a critical function in the reloading workflow: it standardizes cast bullet diameter to exact specifications while simultaneously seating and crimping gas checks—three essential operations in one compact tool. Whether you're a serious competitive shooter, hunting enthusiast, or precision rifle builder, this kit eliminates the guesswork from cast bullet preparation and ensures consistent velocities and accuracy downrange.

Built to integrate seamlessly with any standard 7/8x14 thread reloading press, the Lee Classic Bullet Size Kit .460" uses a die-and-punch assembly that sizes cast lead bullets to the exact .460" diameter specification required for proper chambering and reliable feeding. The gas check seating and crimping function ensures that soft lead projectiles maintain their integrity under the pressures of firing, preventing leading in the bore and maximizing barrel life. Cast bullets naturally vary in diameter due to mold wear and cooling variables; this kit compensates for those inconsistencies, producing uniform ammunition that performs with the precision of commercial factory loads. Note that Lee Liquid Alox lubricant and a compatible reloading press are required to operate this kit and are sold separately.

This kit is ideal for handloaders working with larger calibers—particularly .460 S&W Magnum and similar big-bore cartridges—where cast bullet performance directly impacts terminal ballistics and shooter control. Installation is straightforward: the sizing die threads into your existing press in seconds, and the punch mechanism operates on the normal press stroke. Reloaders who embrace cast bullets gain significant cost savings per round while maintaining factory-level accuracy when proper sizing and gas check preparation are applied. Weighing just 0.63 lbs with compact dimensions, this tool takes minimal bench space while delivering professional-grade results for serious ammunition builders.
