Lee Bullet Sizer & Punch .317"

The Lee Bullet Sizer & Punch .317" is a precision reloading tool designed for handloaders who work with cast bullets and gas-checked ammunition. This specialized sizing die fits any Lee Breech Lock enabled reloading press, making it an essential component for shooters who prefer the economy and consistency of cast projectiles. Whether you're loading for pistol or rifle applications, this bullet sizer delivers the dimensional control necessary for reliable chambering and consistent ballistic performance.

This Lee Bullet Sizer & Punch .317" features dual functionality—it simultaneously sizes cast bullets to precise diameter specifications while seating and crimping gas checks in a single operation. The .317" sizing specification ensures proper fit in bore-sized applications, critical for minimizing leading and fouling in barrels that demand tight tolerances. The integrated punch mechanism eliminates the need for separate sizing and gas check seating steps, reducing press setup time and improving production efficiency for high-volume reloaders. Compact dimensions (3.7 x 0.85 x 5 inches) and lightweight design (0.13 lbs) make it easy to manage and swap between multiple sizing dies without cluttering your reloading bench.

Reloaders who cast their own bullets or source quality cast projectiles will find this tool indispensable for achieving bore-size accuracy and ensuring gas checks seat properly for optimal performance. Used in conjunction with the Lee Breech Lock Bullet Sizer Kit, Lee Liquid Alox lubricant, and a compatible Breech Lock reloading press, this punch delivers repeatable results for pistol hunters, cowboy action competitors, and precision rifle enthusiasts. Its compatibility with the Lee Breech Lock system means quick changeover between calibers and bullet sizes, making it ideal for shooters working across multiple rifle and handgun platforms.
