.223 Remington Micrometer Neck Sizing Die Set

.223 Remington Micrometer Neck Sizing Die Set

The Lee Neck Sizing Die Set includes a neck-sizing die (combined decapping/neck-sizing die that sizes the case neck only), a micrometer bullet-seating die, a universal shell holder, a powder dipper and instructions. This set is intended for reloading brass that has been fired only in your specific firearm.

Using these dies produces the most accurate ammunition by neck-sizing only; the rest of the case is left as-fired. Cases resized this way are fire-formed to the exact chamber of the rifle from which they were originally fired, so they undergo less case deformation on subsequent firings than newly formed or full-length resized cases. That yields more consistent primer/start pressure and therefore improved accuracy. Such ammunition should be used reliably only in the same firearm from which the cases were fired. Not recommended for use in semi-automatic or lever-action rifles; typically used with bolt-action rifles.

Set contains:

• Neck Sizing Die (combined decapping / neck-sizing die that sizes the case neck only)
• Micrometer Bullet Seating Die (precision seating die with micrometer adjustment)
• Universal Shell Holder
• Powder Dipper
• Instructions

Micrometer bullet seating die for precise and consistent bullet seating

Features dead length bullet seating with smooth, accurate adjustment. Tests prove sliding bullet guides provide cartridges with the least bullet runout. When used as a dead length bullet seating die, the body contacts the shell holder assuring precise uniform seating depth.

Laser engraved micrometer thimble and body is easy to read with divisions representing one thousandth of an inch, reads just like a precision depth micrometer. Infinitely adjustable, providing precision bullet seating depth.

Bullet seating stem is machined and burnished to seat nearly any point style bullet without damage or marking.

The case mouth and bullet are held in perfect alignment by a floating bullet guide. The bullet guide is provided with radial clearance to allow the case and bullet guide to align perfectly with the bullet seater screw.

The floating bullet guide is reversible, simply unthread guide and re-install to allow seating and crimping simultaneously, an exclusive feature to Lee.
