The Lyman Neck Expanding "M" Die #26 (SKU: LY-MD26) is a precision reloading tool engineered to improve neck tension and bullet alignment for .26 Caliber and 6.5mm cartridges. Unlike standard expander buttons that can stretch the case neck, this die utilizes a specialized two-step expander plug to prepare brass for consistent bullet seating. Highly regarded by Australian precision shooters and benchrest competitors, this mechanical tool ensures uniform neck tension, which is critical for achieving tight groups at the range. It is fully compatible with standard reloading presses using industry-standard threads.

• Two-Step Expanding Process: The specialized expander plug first expands the inside of the case neck to slightly under bullet diameter, then creates a precise step at the mouth to allow the bullet to sit perfectly centered.
• Prevents Bullet Shaving: By creating a slight flare at the case mouth, it eliminates the risk of shaving lead off cast bullets or damaging the jackets of flat-base projectiles during seating.
• Extends Brass Case Life: Because the die does not pull through and stretch the case neck like standard expander buttons, it minimizes work-hardening of the brass, allowing for more reloads per case.
• Standard Thread Compatibility: Features standard 7/8"x14 threads, allowing seamless integration with almost all popular single-stage and turret reloading presses on the Australian market.
• No Power Requirements: This is a purely mechanical, hand-operated tool, requiring no electrical power, 240V input, or RCM/SAA certification.
