The Redding 55319 6mm PPC Competition Seating Die provides straight-line bullet seating and precise seating depth control for handloaders assembling 6mm PPC ammunition. Engineered for standard 7/8"-14 threaded reloading presses, this mechanical die incorporates a precision-ground internal sliding sleeve that captures and aligns both the cartridge case and the 0.243-inch bullet prior to seating. This straight-line system reduces bullet runout and improves concentricity. An integrated, click-free micrometer adjuster allows reloaders to tune cartridge overall length (COAL) with stepless precision and a zero-set capability.

Key Features

• Straight-Line Sliding Sleeve: Features a close-tolerance internal sliding chamber sleeve that aligns the cartridge case and bullet simultaneously before the seating stem engages.
• Precision Micrometer Adjustment: Features a calibrated micrometer head marked in 0.001-inch increments, delivering 0.050 inches of travel per revolution for precise cartridge overall length adjustments.
• Floating Seating Stem: Houses a precision-ground, tight-tolerance standard seating stem that reduces bullet distortion and promotes concentric bullet alignment.
• Zero-Set Adjustment: Enables the user to re-index the micrometer scale to zero at a preferred seating depth for reference across varying reloading batches.
• Standard Press Threading: Machined with industry-standard 7/8"-14 threads for compatibility with standard single-stage and turret reloading presses using a #12 shellholder.

Who is the Redding 6mm PPC Competition Seating Die for?

• Benchrest competition shooters — requires the 0.001-inch micrometer adjustment increments and straight-line sliding sleeve of this 6mm PPC competition seating die to minimise bullet runout and precisely seat projectiles to rifle lands.
• Precision varmint hunters reloading 6mm PPC — relies on the 0.050-inch-per-revolution micrometer head and zero-set reference feature on this 6mm PPC seating die to adjust cartridge overall length when tuning loads for specific field rifles.
• Extreme accuracy rifle handloaders — uses the standard 7/8"-14 die threading to achieve straight-line cartridge and bullet alignment on conventional single-stage presses without dedicated benchrest arbor presses.

Less suitable for: Reloaders working with unresized cases fired in oversized custom chambers that exceed strict factory dimensions, applications requiring integrated bullet crimping, or reloaders seating sharp Very Low Drag bullets without fitting the optional VLD seating stem (part #55724); these requirements are better served by standard full-length sizing dies, dedicated crimping dies, or VLD-profile seating dies.
