Lee 260 Remington Cartridge Die Set
Die Lee Limited Production 2-Die Set for Caliber .260 Remington.
This precision-engineered kit includes two high-grade steel dies specifically designed for the meticulous reloading and resizing of .260 Remington brass cases, essential for achieving optimal ballistic performance and consistent chambering in metallic and semi-metallic ammunition.
The set comprises the following components:
Full-Length Sizing Die: This die is expertly crafted to recalibrate the brass case by removing the spent primer and slightly expanding the neck diameter. This process ensures the case dimensions conform precisely to SAAMI specifications, facilitating reliable chambering and extraction while maintaining the structural integrity of the brass.
Seating Die: Adjustable for precise bullet seating depth, this die allows the reloader to insert projectiles to the exact depth required for optimal internal ballistics and pressure control. It also initiates the case neck closure around the bullet, but care must be taken to avoid excessive crimping, which can deform the case neck into a rolled or rizo shape, potentially compromising accuracy and feeding reliability.
For applications requiring a robust crimpsuch as lever-action or semi-automatic firearmsthe use of the Factory Crimp Die (Ref. 90977) is highly recommended. This specialized die enables a strong, uniform crimp without damaging the brass, ensuring the cartridge maintains consistent overall length and bullet retention under dynamic cycling conditions.
The kit also includes a Shell Holder compatible with standard reloading presses, providing secure case retention during resizing and seating operations.
Additionally, a Powder Measure Scoop is provided to facilitate precise and repeatable powder charges, critical for maintaining consistent muzzle velocities and safe chamber pressures.
Included is a comprehensive Load Data Chart tailored for non-Spanish powder formulations, offering detailed charge weights, pressure limits, and ballistic performance metrics to guide reloaders in developing safe and effective loads.
It is imperative to lubricate the brass cases thoroughly prior to full-length resizing to prevent case sticking and potential damage to both the case and die. Proper lubrication ensures smooth die operation and extends the lifespan of your brass and tooling.
This Lee Limited 2-Die Set represents a fundamental component in the precision reloaders toolkit, engineered to deliver consistent, high-quality ammunition tailored for the .260 Remington cartridge, optimizing both accuracy and reliability in hunting, target shooting, and tactical applications.
