Lee Precision .460'' Diameter Classic Bullet Size Kit

The Lee Precision .460" Diameter Classic Bullet Size Kit is a straightforward, press-mounted solution for handloaders who cast their own bullets. If you're sizing cast rounds and want to avoid the complexity of separate nose punches and finicky gas check setup, this kit handles both tasks in one pass through your single-stage reloading press. Bullets feed nose-first through the sizing die—a design that eliminates the need for specialized punches and lets you seat and crimp gas checks automatically as the bullet is pushed through.

The kit is complete for .460" diameter bullets and captures sized rounds in its integrated container, so you're not chasing projectiles across the bench. It threads onto any standard single-stage press with 7-8x14" threads, taking the place of your shell holder in the ram. One workflow: lubricate your cast bullets with liquid Alox, press a gas check onto the bullet base, position it on the punch, and run it through the sizing die. Out comes a sized, gas-checked bullet ready for loading.

Lee's approach here is practical—no frills, just function. It's built for the reloader who values speed and simplicity over complexity, especially if you're processing volume and want to consolidate sizing and gas-check crimping into a single operation. Keep in mind that this kit is designed for single-stage presses only, and you'll need to supply your own press and bullet lubricant.

Frequently Asked Questions

Will this kit work on my progressive or turret press?

No—this kit is designed for single-stage presses only. Do not use it on progressive or turret equipment.

Do I need to buy anything else to use this kit?

Yes. You'll need a single-stage reloading press with 7-8x14" threads and bullet lubricant (liquid Alox is recommended based on the design). The kit does not include a press or lubricant.

What size should I order if I'm casting bullets?

Lee recommends selecting a sizing kit that is .001" larger than the groove diameter of your cast bullets. For this kit, that means it sizes .460" diameter projectiles—verify that matches your bullet specifications before ordering.

How do gas checks work with this kit?

Lubricate your cast bullet, press a gas check onto its base, seat it on the punch, and push the assembly through the sizing die. The die sizes the bullet and automatically seats and crimps the gas check in one motion.
