The Lyman Deluxe Carbide Expander/Decapping Rod Assembly 24 (SKU: LY-CDRA24) is a premium internal upgrade designed for precision metallic cartridge reloading. Engineered to fit standard Lyman and RCBS rifle sizing dies, this mechanical assembly simultaneously removes spent primers (decapping) and expands the case neck of .24 calibre (6mm) brass cartridges, such as the popular .243 Winchester. By incorporating a super-hard, ultra-slick carbide expander button, this assembly drastically reduces friction when being pulled through the case neck. This mechanical advantage eliminates the need for inside-neck lubrication, prevents case neck stretching, and minimizes the need for frequent trimming, ultimately extending the service life of your brass cases.

Key Features of the Lyman LY-CDRA24:

• Super-Hard Carbide Button: The ultra-slick carbide expander button glides through the case neck with minimal friction, eliminating the need for tedious inside-neck lubrication and reducing brass fatigue.
• Free-Floating Mechanism: The carbide button free-floats on the rod, allowing it to self-center within the case neck. This reduces runout and ensures superior concentricity for more accurate ammunition.
• Adjustable Positioning Sleeve: Features two height adjustment positions on the rod, allowing reloaders to customize exactly when the expander button passes through the neck during the press stroke to optimize leverage.
• Replaceable Decapping Pin: Equipped with a standard, robust decapping pin at the tip to easily punch out spent primers during the sizing stroke.
• Broad Die Compatibility: Designed to fit all standard Lyman rifle sizing dies while also being fully compatible with RCBS rifle sizing dies.

Who It Is For:

This deluxe assembly is specifically engineered for Australian precision rifle shooters, target competitors, and hunters reloading .24 calibre or 6mm cartridges like the .243 Winchester. Whether you are looking to upgrade an existing Lyman or RCBS die set or replace a worn steel expander rod, this carbide assembly is ideal for those who want to streamline their reloading process. By removing the step of inside-neck lubrication and reducing physical effort on the press linkage, it is a highly practical upgrade for high-volume reloaders and competitive shooters who demand maximum concentricity, consistent neck tension, and prolonged brass life.
