Die Caliber 280-7mm Express LEE Reloading Dies
Lee Precision 3-Die Set for Caliber .280/7mm Express Remington offers a comprehensive reloading solution designed for precision metallic and semimetallic cartridge case resizing and bullet seating. This professional-grade kit includes three high-quality steel dies engineered to optimize the reloading process for hunters and marksmen demanding reliability and accuracy in their ammunition preparation.
The set comprises the following dies:
1. Full-Length Sizing Die: This die is engineered to recalibrate the cartridge case by removing the spent primer and expanding the neck slightly. It ensures the case dimensions are restored to factory specifications, facilitating consistent chambering and extraction. Proper lubrication of the case is essential before resizing to prevent case head separation and ensure smooth die operation.
2. Bullet Seating Die: This adjustable die allows precise control over bullet seating depth, enabling the projectile to be seated at the optimal position within the case neck. It also initiates the case neck crimping process to secure the bullet firmly. Care must be taken to avoid excessive crimping at this stage, as over-crimping can deform the case neck and compromise cartridge integrity. For applications requiring stronger case neck retention, especially in lever-action or semi-automatic firearms, the use of the dedicated crimp die is recommended.
3. Factory Crimp Die: Specifically designed to apply a robust and uniform crimp to the case mouth without damaging the cartridge, this die allows for a controlled and repeatable closure of the case neck. It is particularly beneficial when loading ammunition for firearms that subject cartridges to additional stress during cycling, such as lever-action rifles and semi-automatic platforms. Utilizing this die enhances feeding reliability and prevents bullet setback or movement under recoil.
Additionally, the kit includes a compatible shell holder tailored for use with standard reloading presses, ensuring secure case retention during resizing and seating operations.
For precise powder measurement, a calibrated powder dipper is provided, facilitating consistent charge weights critical for ballistic performance and safety.
The package also contains a detailed load data chart, optimized for non-Spanish powders, offering recommended charge weights and ballistic parameters to assist reloaders in achieving optimal performance and safety margins.
It is imperative to apply a suitable case lubricant before the full-length sizing operation to minimize friction and prevent case damage. Proper maintenance of dies and adherence to recommended reloading practices will extend tool life and ensure consistent ammunition quality.
This Lee Precision 3-Die Set for .280/7mm Express Remington is an essential toolset for reloaders seeking to produce high-quality, reliable ammunition tailored for hunting and precision shooting disciplines.
