Lee 90061 New Lube & Size Kit One Kit .451 Diameter Sizer Die|Punch|Case 7|8x14 Threads in.

The Lee 90061 New Lube & Size Kit is a cast bullet sizing solution purpose-built for single-stage reloading press operators. If you're casting your own projectiles for handloads, this .451-diameter sizer die speeds up the tedious work of preparing cast bullets for the loading bench. The kit includes the sizing die, punch, and collection case—everything you need to size and lubricate cast bullets in one operation, so you're not fumbling with separate tools or dealing with bullets rolling across your bench.

The kit works nose-first: you push the bullet through the die rather than seating it base-first, which eliminates the need for custom nose punches. If you're using gas-checked bullets, the kit will automatically seat and crimp the gas check in place as the bullet passes through—a genuine time-saver compared to doing it by hand. Sized bullets drop into the collection case, keeping your workspace organized and preventing stray projectiles. The die features standard 7/8x14" threads, so it screws into any single-stage press without modification.

Keep in mind this kit is designed for single-stage presses only; don't attempt it on a progressive or turret machine. You'll need a single-stage press, a bottle of liquid alox lubricant (sold separately), and cast bullets in the correct diameter. Lee recommends selecting a sizing kit that's .001" larger than your bullet's groove diameter for optimal fit and performance.
