The Redding 7mm PRC Competition Seating Die is a precision reloading tool engineered to seat 0.284" diameter projectiles into 7mm Precision Rifle Cartridge cases with minimal concentricity runout. Built with an internal, precision-ground sliding chamber sleeve, the die fully supports the cartridge case and bullet in straight-line alignment before seating begins. Depth adjustments are controlled via a top-mounted micrometer calibrated in 0.001" increments, with 0.050" of linear travel per complete revolution. The unit mounts to standard reloading presses via an industry-standard 7/8"-14 TPI thread and includes interchangeable seating stems for standard and VLD bullet profiles.

Key Features

• Straight-Line Alignment Sleeve: Features an internal sliding chamber cut to minimum SAAMI/CIP dimensions that encapsulates the 7mm PRC case body and projectile to prevent runout during seating.
• Micrometer Depth Control: Click-free micrometer mechanism allows fine Cartridge Base to Ogive (CBTO) and overall length adjustments in 0.001" increments, complete with a resettable zero.
• Free-Floating Seating Stems: Ground seating stems align with projectile ogives to prevent bullet tip deformation and maintain axial alignment.
• Standard Press Interface: Operates on standard 7/8"-14 TPI single-stage and turret reloading presses.

Who is the Redding 7mm PRC Competition Seating Die for?

• Extreme Long Range Target Shooters — Requires precise depth tuning using the 0.001" micrometer adjustment increments on this 7mm PRC bullet seating die to seat 0.284" projectiles to exacting jump tolerances.
• PRS Match Shooters — Needs consistent, runout-free ammunition across high-volume batch loading by running this 7mm PRC bullet seating die on standard 7/8"-14 TPI reloading presses.
• Long-Range Hunters — Relies on uniform 0.001" seating depth repeatability and straight-line sleeve alignment to maintain consistent ballistic performance with match-grade 0.284" hunting projectiles.

Less suitable for: Reloading other 7mm cartridges (such as 7mm Remington Magnum or 7mm-08) or other PRC variants (such as 6.5 PRC or 300 PRC), which require a caliber-specific seating die, or for cases fired in oversized chambers without full-length resizing, which require standard non-sleeved seating dies to prevent binding.
