The RCBS 7mm Rem Mag Neck Die Set (Model R13602) is a specialized two-die reloading set designed for precision handloading of fired 7mm Remington Magnum bottleneck rifle brass. Machined from proprietary case-hardened steel, this mechanical tool includes a neck sizing die and a bullet seater die. By resizing only the neck of the cartridge case, this set prevents over-working the brass, which preserves the fire-formed chamber fit of the casing to a specific rifle and extends overall case life.

Key Features

• Neck-Sizing Precision: The first die resizes only the neck of the 7mm Remington Magnum brass and de-primes the spent primer, leaving the fire-formed body and shoulder dimensions completely untouched.
• Bullet Seating and Crimping: The second die seats the bullet to the user's desired depth and can apply a roll crimp when required.
• Hardened Steel Construction: Built from case-hardened steel to ensure long-lasting durability and resistance to wear under heavy, repetitive bench use.
• Universal Compatibility: Designed with standard 7/8"-14 thread patterns to fit the vast majority of standard single-stage and progressive reloading presses.

Who is the RCBS 7mm Rem Mag Neck Die Set for?

• Precision 7mm Remington Magnum handloaders — seeking to maximize accuracy by neck-sizing fired brass to match a specific rifle chamber, utilizing the standard 7/8"-14 thread interface to work with their existing single-stage or progressive presses.
• High-volume reloaders seeking extended brass life — seeking to prevent over-working their 7mm Remington Magnum brass by resizing only the cartridge neck with this two-die set, which weighs 0.58 kg and is constructed of hardened steel to ensure long-term durability over thousands of reloading cycles.

Less suitable for: shooters who need to fire their reloaded ammunition in multiple different firearms, or when the cartridge shoulder has expanded to the threshold where the bolt is difficult to close; in these scenarios, a full-length sizing die or a dedicated body die must be used instead of a neck-only sizing die.
