Lee Bullet Sizer & Punch .309"

The Lee Bullet Sizer & Punch .309" is a precision reloading tool designed for shooters who cast their own bullets or work with cast projectiles. This Lee Precision sizing die reduces bullet diameter to exact specifications while the integral punch seats and crimps gas checks in a single operation, producing consistently dimensioned ammunition for improved accuracy and feeding reliability across bolt-action rifles and other firearms chambered in .309" caliber cartridges.

This Lee bullet sizer operates within the Breech Lock reloading press system, leveraging Lee's quick-change bushing design for fast tool changeover between different reloading operations. The .309" diameter specification accommodates cast bullets intended for cartridges like the .308 Winchester, 7.62×51mm NATO, and similar rifle rounds where tight bullet-to-bore fit enhances velocity consistency and reduces flyer shots. The combined sizing and gas check crimping function streamlines the reloading workflow, eliminating the need for separate crimping tools and reducing setup time on the press.

Reloaders who cast their own rifle bullets—whether for long-range precision shooting, historical cartridge research, or cost-effective high-volume practice—benefit from the ability to size cast projectiles to precise dimensions before seating. This tool is essential for anyone already invested in a Breech Lock press system who wants to work with cast ammunition. Lee Liquid Alox lubricant, a compatible reloading press, and the Breech Lock Loading Kit are required separately to complete the reloading setup and begin producing custom ammunition.
