The RCBS Matchmaster Competition Full-Length Bushing Die Set 6.5mm-284 Winchester (R28708) is a premium, two-die system engineered for handloaders demanding the highest level of concentricity and neck-tension control. Machined from precision-drilled, hand-polished, and case-hardened steel, this set is built for reloading 6.5mm-284 Winchester (also known as 6.5x284 Norma) cartridges. Operating without any electrical components, the dies feature a standard 7/8″-14 thread interface, making them universally compatible with almost all standard single-stage and turret reloading presses on the market.

Key Features

  • Full-Length Bushing Sizing Die: Resizes the cartridge body back to SAAMI specifications while using interchangeable neck bushings (sold separately) to control neck tension to thousandths of an inch without overworking the brass.
  • TiCN Expander Ball: Features a Titanium Carbo-Nitride (TiCN) coated expander ball on the decapping rod, reducing friction and brass buildup during case extraction.
  • MatchMaster Seating Die: Features a specialized, side-loading bullet-seating window with an internal retention system, allowing users to drop the bullet directly into the window rather than balancing it on the case mouth.
  • Micrometer Seating Depth: Equipped with an oversized adjustment knob featuring high-visibility hash marks for fine-tuning bullet seating depth in highly precise increments of 0.001 inches.
  • Self-Centering Bullet Stem: Incorporates a free-floating, self-centering bullet seating stem to optimize overall cartridge concentricity.

Who is the Rcbs 6.5mm-284 Win Matchmaster Competition Full Length Die Set for?

  • Competitive long-range target shooters — require the micro-fine 0.001-inch seating depth adjustments provided by the MatchMaster bullet seating die to achieve the precise cartridge consistency necessary for sub-MOA performance in 6.5mm-284 Winchester rifles.
  • Benchrest precision reloaders — require the highly customizable neck tension afforded by the interchangeable bushing system of this 6.5mm-284 rifle reloading die set, allowing them to optimize brass life and cartridge release tension while utilizing a standard 7/8″-14 thread press interface.

Less suitable for: High-volume shooters using other 6.5mm chamberings such as the 6.5 Creedmoor or 6.5 PRC, as this set is strictly dimensioned for 6.5mm-284 Winchester brass. It is also less suitable for high-speed, progressive reloading workflows, where standard non-bushing full-length dies or small-base progressive dies are better optimized for maximum throughput than manual single-stage bushing dies.
