Lee 90686 New Lube & Size Kit .323 Diameter Sizer Die|Punch|Case 7|8x14 Threads in.

The Lee Precision Lube & Size Kit for .323 diameter bullets is a straightforward solution for reloaders who cast their own projectiles. This sizing setup works with any single-stage reloading press using standard 7/8x14 threads, letting you size and lubricate cast bullets efficiently without needing specialized tooling. The kit comes complete with the sizing die, punch, and collection case—everything you need to process bullets for .323-diameter applications, whether you're working with 8mm rifle rounds or other cartridges in that bore size.

Unlike some sizing systems, this Lee kit uses a push-through design: bullets go nose-first through the die, which means no separate nose punch is required. The included punch replaces your shell holder in the press ram, streamlining the setup. If you're using gas-check bullets, the system automatically seats and crimps the gas check in place as the bullet passes through—a real time-saver when you're processing volume. Sized bullets drop into the included container, keeping your workflow organized and bullets ready to load.

Keep in mind this kit is designed for single-stage press use only. You'll need to supply your own reloading press and bullet lubricant (liquid Alox works well). For best results, select a sizing die that's .001" larger than your bullet's groove diameter to ensure proper sizing without excessive friction. If you're new to cast-bullet reloading, this is a solid entry point—it eliminates guesswork and speeds up the most tedious part of the casting and sizing process.
