Lee Precisiom
The Lee Precision .300 Winchester Short Magnum collet neck sizing die delivers repeatable precision for handloaders who demand consistency shot after shot. Unlike conventional sizing dies that rely on lubricated cases and bushings, this collet-style die uses a precision mandrel and collet mechanism to squeeze the case neck into a perfect fit with minimal runout. That means cleaner reloading sessions without the mess of case lube, and brass that lasts dramatically longer than cases processed through standard dies.
If you're loading match ammunition for long-range hunting or precision rifle competition, case neck uniformity matters. The collet design in this Lee die prioritizes that uniformity by applying even pressure around the entire neck, which translates to tighter velocity spreads and more predictable bullet seating. Over the life of a brass batch, you'll notice your cases stay in service longer—Lee claims a tenfold increase in case life compared to traditional sizing methods—which means fewer cartridges scrapped and lower per-round reload costs.
This is a neck sizing die only, so it pairs with your existing Lee or compatible press and your chosen decapping tool or separate decapping die. It's purpose-built for the .300 Winchester Short Magnum, so verify your caliber before purchase. Reloaders who've invested in quality brass and developed accurate loads recognize that case prep and sizing are where precision begins; this die is built for shooters who take that seriously.

No. The collet-and-mandrel design sizes without lubrication, which eliminates prep and cleanup compared to conventional dies.
Yes, this collet neck sizing die is compatible with standard Lee presses and other single-stage or progressive presses that accept standard reloading dies.
This is a neck sizing die only, so you'll need a separate decapping tool or decapping die, a reloading press, brass, powder, primers, and bullets. You may also want a separate FL sizing die if you intend to fully resize cases.
Lee states that cases sized with their collet dies last roughly ten times longer than cases processed with conventional sizing dies.
