Lee Bullet Sizer Kit For Bullet Sizer & Punch

The Lee Bullet Sizer Kit is the quickest way to process cast bullets for reloaders who want consistent sizing without the extra hassle. Built around Lee's proven single-stage press system, this kit lets you size cast bullets nose-first through the die—eliminating the need for specialized nose punches and simplifying your casting-to-loading workflow. Once a bullet is pushed through, gas checks are automatically seated and crimped in place, and finished rounds drop into the included capture container for easy collection.

If you're casting your own projectiles for rifle cartridges, choosing the right bullet sizer kit matters: you'll want to select a sizing die that's .001" larger than your bullet's groove diameter to get a proper fit without deformation. The kit threads onto any single-stage press with standard 7-8x14" threads, and the push-through punch replaces your shell holder in the ram, so setup is straightforward. The container keeps your sized bullets organized and ready to move to the next stage of handloading.

This is a reloading essential for cast-bullet shooters who want to keep their workflow simple and their rounds consistent. Note that this kit is designed for single-stage presses only; if you want to crimp gas checks during sizing, you'll apply liquid alox (sold separately) to the bullet base before seating the gas check on the punch.
