The Lee Precision .357 Lube & Size Kit is a cast-bullet sizing solution built around a single-stage reloading press. If you're casting your own bullets for handgun or rifle loads, this kit handles the critical step of sizing cast projectiles to precise dimensions—a process that can be time-consuming if done manually. The kit includes everything you need to get started: the .357-diameter sizing die (7/8x14 threads, standard on most single-stage presses), a push-through punch that doubles as your sizing ram, and a capture case to contain sized bullets as they exit the die. This is a no-fuss approach: bullets go nose-first through the die, no special nose punches required.
The real convenience of this kit emerges when you're working with gas-check bullets. Load your casting mold with liquid Alox or similar lube, seat a gas check on the bullet base, and place the bullet on the punch. As you press the bullet through the sizing die, it's sized to .357 diameter and the gas check is simultaneously crimped in place—a two-step job accomplished in one stroke. Sized bullets drop directly into the included container, keeping your workspace organized and your production moving. The system is designed exclusively for single-stage presses; it won't work on progressive or turret machines.
One critical note: cast bullets should be sized about .001" larger than their groove diameter. This particular kit is sized at .357 diameter, so it's suited to bullets cast for .357 Magnum, .357 Maximum, or similar cartridges with that nominal bullet diameter. Your reloading press and bullet lubricant are sold separately. If you're new to casting or transitioning from jacketed bullets, this kit removes much of the guesswork and manual labor from the sizing phase.
| Bullet Diameter | .357 |
| Die Thread Standard | 7/8x14 |
| Compatible Press Type | Single-stage presses only |
| Components Included | Sizing die, push-through punch, collection case |
| Not Included | Reloading press, bullet lubricant |
No. The Lee Lube & Size Kit is engineered for single-stage presses only. Progressive and turret machines have different ram and station geometries that are incompatible with this system.
Yes. You'll need a single-stage reloading press and bullet lubricant (liquid Alox is recommended). The kit itself provides the die, punch, and collection case.
Cast bullets sized in this die should be cast .001" larger than groove diameter—so for a .357 Magnum or similar cartridge, you'd typically cast bullets slightly oversized and let the die bring them to the final .357 dimension.
Yes. Apply liquid Alox to the bullet, seat a gas check on the base, place the bullet on the punch, and push through the die. The sizing die will crimp the gas check in place as it sizes the bullet.
