The Lee Precision .376" Diameter Classic Bullet Sizing Kit is a cast bullet sizing solution built for reloaders who want speed and simplicity without complexity. If you're casting your own projectiles for handloading, this kit handles the critical step of sizing cast bullets consistently—and it does the job in a straightforward way that works with equipment you already own. The kit fits standard 7–8×14" threads, so it mounts directly into any single-stage reloading press you have on the bench.
What sets this approach apart is the nose-first design: bullets feed through the sizing die tip-first, which eliminates the need for special nose punches. That simplicity carries through to gas check sealing too. If you're loading magnum pistol or rifle rounds that call for a gas check, the kit crimps and seats it automatically as the bullet passes through. Sized bullets drop neatly into the included container, keeping your work area organized and making it easy to batch your ammunition prep.
This is a complete, single-size kit—it's calibrated for .376" diameter cast bullets. The .001" overbore sizing standard means it'll handle cast projectiles slightly larger than groove diameter, which helps prevent gas cutting and improves consistency. Keep in mind that a single-stage press is required; this kit isn't compatible with progressive or turret designs. You'll need to supply your own press and liquid alox bullet lubricant to get started.
