Lee 90036 New Lube & Size Kit .225 Diameter Sizer Die|Punch|Case 7|8x14 Threads in.

The Lee Precision .225 Diameter Lube & Size Kit is a cast-bullet sizing solution built for reloaders who want to streamline their handloading workflow. This kit combines a sizing die, punch, and collection case—everything you need to size and lubricate cast bullets in a single pass through your single-stage press. Standard 7/8x14 threads mean it'll fit any standard single-stage reloading press you already own, no special adapters required.

Cast bullet sizing doesn't have to be a separate, time-consuming operation. With the Lee system, you push bullets nose-first through the die, which means no fussy nose punches or custom tooling to manage. If you're loading cast bullets with gas checks, the kit automatically seats and crimps them in place as the bullet travels through the die. Sized bullets drop directly into the included container, keeping your bench organized and your workflow moving. It's the kind of practical design that separates Lee from more complicated approaches.

This kit is sized for .225 diameter bullets and works best when you select a die that's .001" larger than your bullet's groove diameter—a simple rule that ensures proper sizing without deforming the projectile. Keep in mind that you'll supply your own single-stage press and bullet lubricant (liquid alox is the standard choice). The kit is designed specifically for single-stage press operation and won't work on progressive or turret machines.

Frequently Asked Questions

Will this kit work with my progressive or turret press?

No. This kit is designed exclusively for single-stage presses. Lee does not recommend or support using it on progressive or turret machines.

What do I need to supply separately?

You'll need to provide your own single-stage reloading press (which must have 7/8x14 die threads) and bullet lubricant. Liquid alox is the standard choice for cast bullet lubrication.

Can this kit size cast bullets with gas checks?

Yes. After lubricating your bullets with liquid alox, place a gas check on the base of the bullet, set it on the punch, and push through the die. The sizing die will size the bullet and automatically seat and crimp the gas check in one pass.

What diameter should I choose for my cast bullets?

Select a sizing die that is .001" larger than your bullet's groove diameter. This ensures proper sizing without deformation. The .225" diameter in this kit is sized accordingly, but always verify against your specific cast bullets.
