Lee Precision 38 Special, 357 Magnum Undersized Carbide Sizing Die
$22.49
The Lee Precision 38 Special and 357 Magnum Undersized Carbide Sizing Die is built for reloaders who want tighter, more consistent case dimensions shot after shot. This carbide sizing die is designed .003" smaller than Lee's standard carbide sizing dies, which means it sizes cases down more aggressively — ideal if you're working with loose brass or want a snug fit in your chamber. Carbide dies eliminate the need for case lube on rifle rounds and make handgun reloading faster and cleaner, and this undersized version takes that convenience a step further for precision-minded shooters.
Whether you're loading 38 Special for match shooting, personal defense, or practice, or working up 357 Magnum for hunting or duty use, this die helps you achieve the tight case fit that reduces variability. Reloaders who prioritize consistency and who've found standard sizing dies leave their brass slightly loose will appreciate the tighter sizing window this die delivers. Lee Precision carbide dies are known for durability and long service life — you'll size thousands of rounds before replacement becomes an issue.
This is a sizing die only and is part of a complete reloading die set; you'll need a press, shell holder, and other dies (decapping, expanding, seating) to complete your reloading setup. If you already own Lee reloading equipment or other standard three-die kits for these calibers, this undersized die is a direct substitute for the sizing stage that gives you finer control over case dimensions.
