The Lyman M Expander Die .44 (SKU: LY-MD44) is a precision-engineered, mechanical reloading tool designed to enhance the accuracy and consistency of handloaded .44 calibre ammunition. Unlike standard expander buttons that pull through the case neck and risk stretching or distorting the brass, this specialized die uses a precise downward expansion process. It is compatible with standard 7/8" x 14 thread reloading presses, making it a versatile addition to any reloading bench. Designed for purely mechanical operation, it requires no electrical power or Australian 240V mains connection, making it a durable, long-lasting workshop tool for Australian sporting shooters and hunters reloading for .44 Magnum lever-action rifles or revolvers.

Key Features:

• Two-Step Expansion Plug: The first step expands the inside of the case neck to just under bullet diameter for precise, uniform neck tension. The second step expands the top 1/16" of the case mouth to slightly over bullet diameter, creating a pocket that aligns the projectile perfectly centered with the case axis.
• Prevents Bullet Damage: By creating a perfectly aligned pocket, the die prevents the sharp edges of the case mouth from shaving lead or copper plating off cast, plated, or flat-base jacketed bullets during seating.
• Extends Brass Life: The controlled expansion process reduces work-hardening and case mouth splitting, significantly increasing the lifespan of your .44 calibre brass cases.
• Adjustable Flare: The neck expanding plug can be adjusted deeper to provide a traditional outward flare to the case mouth if required by your specific loading process.
• Universal Press Compatibility: Features industry-standard 7/8" x 14 threads to fit major reloading presses from brands including RCBS, Hornady, Lee, and Dillon.
