Description
The Lee Collet Neck Sizing Die for .222 Remington is built for precision handloaders who want to get the most out of their fire-formed brass. Instead of working the entire case like a full-length die, this one uses a steel collet to squeeze the case neck against a precision mandrel. The result is a straight, concentric neck with minimal bullet runout, which is exactly what you want when you're chasing tight groups out of a .222 bolt gun. Since the body of the case is left alone, your brass stays matched to your rifle's chamber and tends to last far longer than fully resized cases.
Why the .222 Remington Collet Die Earns Its Keep
One of the biggest wins with this die is that it needs no case lube. The collet design sizes the neck cleanly and deprimes in the same stroke, so you skip the mess of lubing and cleaning cases afterward. Less brass stretch also means fewer trimming sessions and more loading cycles out of each case. For the .222 Remington crowd that loves punching paper and reaching out on varmints, that consistency pays off downrange.
Getting the Most From This Collet Neck Sizing Die
This die works best with brass that was last fired in the same rifle you plan to reload for. Neck sizing keeps the fire-formed fit intact, so those cases chamber snugly in your gun. It's designed for bolt action and single shot rifles and is not recommended for autoloaders, slide, or lever action guns, where full-length sizing is the better call for reliable feeding.
The die uses the standard 7/8"-14 thread, so it threads right into any common single stage or turret press. Lee also updated the collet in 2019 so a small portion of the neck protrudes through the end of the sizing portion, a change that handloaders had been asking about. It ships in a custom-fit storage container to keep everything protected on your bench.

Frequently Asked Questions
What does the .222 Remington collet neck sizing die actually do?
It sizes only the neck of your fired brass by squeezing it against a precision mandrel with a steel collet. This keeps the case body fire-formed to your chamber and produces a straight neck with reduced runout. The die also deprimes the case in the same stroke.
Do I need case lube with this Lee collet die?
No. The collet design sizes the neck without any case lubricant, so you skip the lubing and cleanup step entirely. That keeps your brass clean and speeds up your loading routine.
Can I use this die for brass fired in a different rifle or for a semi-auto?
Neck sizing is meant for cases that were last fired in the same rifle you're reloading for, since it preserves the fire-formed fit. It's recommended for bolt action and single shot rifles and is not recommended for autoloaders, slide, or lever action guns. If you need rounds that chamber across multiple guns, a full-length sizing die is the better choice.
What press thread does the 91003 die use?
It uses the standard 7/8"-14 thread, so it fits common single stage and turret presses without any adapters. Just thread it in and set it up like any other standard die.
