Will the Redding 55446 competition seating die work with other 6.5mm cartridges like the 6.5 PRC?

No, this die is strictly engineered for the 6.5 Creedmoor cartridge. Attempting to use it with other 6.5mm rounds like 6.5 PRC or 6.5x55 Swedish creates a high risk of improper headspace alignment and sleeve mismatch, which compromises your handloading precision.

Does the Redding 55446 competition seating die include a crimping function?

No, this die is designed purely as a precision bullet seater and does not feature a roll- or taper-crimp ring. If your shooting application requires a crimp, you will need to pass your brass through a separate factory crimp or taper crimp die after seating.

What thread interface and shellholders are required to set up this die on my reloading press?

The Redding 55446 features an industry-standard 7/8"-14 thread interface, making it compatible with most single-stage and turret reloading presses. You will also need to use a Redding Shellholder #1 (such as part #11001 or competition shellholder #11601), which is sold separately.

Are there any electrical compliance requirements or Australian certifications needed for this tool?

No electrical compliance, Australian plugs, or SAA/RCM regulatory approvals apply to this product. The Redding 55446 is a manually operated, non-powered mechanical bench tool designed for standard Australian reloading room environments.

6.5 Creedmoor Seating Die - Redding 55446

The Redding 55446 Competition Bullet Seating Die is a precision reloading tool engineered specifically for the 6.5 Creedmoor cartridge. Built with a patented internal sliding chamber sleeve, the die fully encapsulates and aligns both the 6.5mm (.264") projectile and cartridge case before seating begins. This straight-line mechanical alignment minimizes total indicated runout (TIR) and bullet concentricity issues, delivering the tight tolerances required for match-grade consistency across single-stage and turret reloading presses.

Key Features

Floating Sleeve Alignment: Uses a precision-ground sliding chamber sleeve that straight-aligns the cartridge case and projectile prior to seating, reducing runout to 0.001" to 0.002" TIR.
Direct Micrometer Seating: Features a top-mounted micrometer calibrated in direct 0.001" increments with zero-set functionality for returnable cartridge overall length (COAL) adjustments.
Dedicated Non-Crimping Body: Engineered solely for bullet seating without an internal crimping ring, preventing case shoulder distortion during precision bullet seating.
Standard Press Integration: Machined with industry-standard 7/8"-14 threads to fit standard reloading presses, paired with Redding #1 shellholders.

Who is the Redding 55446 Competition Seating Die for?

Precision Rifle Series competitors — requires precise seating depth adjustments via 0.001" micrometer graduations on this 6.5 Creedmoor competition seating die to fine-tune projectile jump for consistent match velocities.
Long-range hunters — requires minimal runout across 6.5mm / .264" handloads by using this competition seating die to align the projectile and cartridge case for predictable terminal ballistics at distance.
Match-grade handloaders — requires standard 7/8"-14 thread press compatibility combined with precision straight-line seating to reliably achieve total indicated runout tolerances below 0.002".

Less suitable for: Handloaders loading other 6.5mm cartridges such as the 6.5 PRC or 6.5x55 Swedish due to headspace sleeve mismatch, who require a calibre-specific seating die, or high-volume reloaders needing simultaneous crimping, who require a dedicated separate taper or factory crimp die.
