7mm Ultra Mag LEE Die Set for Precision Reloading and Hunting Ammunition
Lee 2-Die Set for 7mm Ultra Magnum Caliber Reloading
This precision-engineered 2-die set, crafted from hardened steel, is specifically designed for the meticulous reloading of 7mm Ultra Magnum cartridges. Ideal for competitive shooters, hunters, and ballistic enthusiasts seeking optimal case resizing and bullet seating performance, this kit ensures consistent, reliable ammunition preparation.
The comprehensive kit includes the following components:
Full-Length Resizing Die: This die performs complete case recalibration by removing the spent primer pocket and slightly expanding the case neck to its original dimensions. It is engineered to maintain case integrity while ensuring proper chamber fit and reliable feeding in semi-automatic and bolt-action rifles.
Bullet Seating Die: Fully adjustable for precise bullet seating depth, this die allows the operator to set the projectile to the optimal depth within the case neck, maximizing ballistic efficiency and accuracy. It also initiates the case neck crimping process; however, care must be taken to avoid excessive crimping, which can deform the case mouth into a rolled edge, potentially compromising chambering and pressure consistency.
Shell Holder: A robust shell holder compatible with standard reloading presses, designed to securely hold the cartridge case during resizing and seating operations, ensuring concentricity and repeatability.
Powder Measure Tool: Included for precise volumetric measurement of propellant charges, facilitating consistent powder loads essential for safe and accurate reloading.
Reloading Data Chart: A detailed load data table is provided; please note that it does not include Spanish powder types. Users should consult appropriate ballistic manuals or manufacturer data for compatible powders and charge weights.
For optimal results, it is imperative to lubricate the cartridge cases thoroughly before resizing to prevent case sticking and to extend die life. Proper lubrication ensures smooth operation and maintains case integrity throughout the reloading cycle.
This Lee 2-die set for 7mm Ultra Magnum is an essential tool for precision metallic and semimetallic cartridge reloading, delivering consistent case sizing and bullet seating critical for high-performance shooting applications.
