The Mighty Armory Gold Match 6.5 PRC sizing die is engineered to full-length size and decap 6.5 PRC brass to true SAAMI specification.
Designed for long-range shooters, PRS competitors, and precision hunters, this die restores fired brass from the case head through the shoulder and neck for controlled headspace, consistent chamber fit, and uniform neck tension.
*6.5 PRC Sizing Dies are offered in two sizes, .290" and .291" diameters. Choose the die that suits your needs. All dies ship with a drop in mandrel shafts to accommodate varying brass thickness.
Full-Length SAAMI Spec Sizing for 6.5 PRC
This 6.5 PRC sizing decapping die is machined to full-length SAAMI spec dimensions. Proper full-length sizing ensures smooth feeding, reliable chambering, consistent chamber pressures, and longer brass life across repeated reload cycles.
This 6.5 PRC full-length sizing die is machined to proper SAAMI dimensions to prevent:
- Under-sizing at the base
- Over-sizing at the neck
- Shoulder distortion
- Inconsistent case body geometry
Full-length sizing the case back to SAAMI Spec dimension ensures:
- Smooth feeding
- Reliable chambering
- Stable chamber pressures
- Longer brass life
Shoulder bump is easily adjusted from zero to -.005 by simply turning the die in or out of the press and verifying with a comparator.
Precision Drop-In Mandrels for Perfect Neck Tension
Each Gold Match 6.5 PRC sizing die includes one drop-in expander mandrels additional sized mandrels can be purchased separately to match different brass thickness and spring back characteristics. The mandrels provide controlled, concentric neck expansion, creating consistent neck tension for reliable bullet grip and uniform pressure curves. The mandrel shaft is Swiss-machined from high-grade tool steel, heat treated for durability, and built to maintain alignment under high round counts.
Ultra-Smooth Bore Finish for Effortless Sizing
The sizing bore is single-point cut and finished to an ultra-smooth surface, 5 bore finish and hardness of 60 Rockwell. This glass-smooth internal finish reduces sizing force, minimizes brass galling, and improves concentricity from case mouth through the shoulder radius. The result is smoother press operation, reduced case deformation, and more consistent headspace control.
Decap and Size in One Pass
The Gold Match 6.5 PRC sizing die sizes and decaps in one pass. Includes two hardened steel decapping pins (.058" and .078" diameters to accommodate small and standard flash hole sizes). This spring-assisted system prevents primer pullback, press chute jams, and primer “ringers,” allowing high-volume decapping with minimal stoppages. The internal threads accept Mighty Armory decapping pins or the Mighty Armory Pointer guide to protect threads when decapping is not required.
Built for High Volume, Built to Last
Machined from high-grade tool steel inside and out, the Gold Match 6.5 PRC sizing die is designed to withstand over a million sizing cycles while maintaining perfect concentricity. Tight tolerances, perfect vertical alignment, and a hardened sizing bore ensure consistent performance whether you’re loading small batches of match ammo or running extended precision loading sessions.

Press & Case Lube Recommendations
For single-stage and turret presses, apply case sizing wax lightly by hand for optimal feel and surface protection.
For progressive presses, use PEG75 lanolin spray lube for smooth, high-volume sizing without case drag.
