The Redding Type S Match Bushing Full Length 2-Die Set (MPN 36420) is engineered for precision handloading of .243 Winchester Ackley Improved ammunition featuring a 40° shoulder angle. Built with standard 7/8"-14 threads to mount in standard single-stage and turret reloading presses, this mechanical set combines a Type S full-length bushing sizing die with a competition seating die to provide exact neck tension management and minimal bullet runout.

• Type S Full-Length Sizing Die: Resizes the case body, bumps the 40° shoulder back to factory specification, and controls neck diameter via interchangeable sizing bushings (sold separately in 0.001-inch increments) without overworking brass.
• Configurable Decapping Assembly: Includes an adjustable decapping rod compatible with standard steel expander buttons, optional carbide expander buttons, or a decapping pin retainer for sizing neck-turned brass without an expander ball.
• Competition Seating Die: Features an internal floating alignment sleeve that centres both the cartridge case and bullet before seating begins, delivering straight-line alignment.
• Micrometer Seating Depth Control: Top-mounted micrometer provides continuous adjustment calibrated in direct 0.001-inch increments, allowing reproducible seating depths that can be zeroed to specific bullet profiles.
• Mechanical Operation: Fully manual tooling requiring no electrical power, housed in a standard storage case weighing approximately 0.6 to 0.7 kg.

Who is the Redding Type S Match Full Length Die Set for .243 Win Ackley Improved for?

• Competitive benchrest and long-range target shooters — relies on the Competition Seating Die with its 0.001-inch micrometer adjustment increments to fine-tune bullet jump and seat projectiles with straight-line alignment for .243 Winchester Ackley Improved rifles.
• Precision handloaders and varmint hunters — requires the Type S full-length sizing die to reliably bump the 40° shoulder for chamber clearance while selecting specific bushing sizes in 0.001-inch steps to preserve brass life and maintain uniform neck tension.

Less suitable for: Standard factory .243 Winchester chambers without a 40° shoulder angle, reloaders seeking neck-only sizing without touching the case body (who require a dedicated bushing neck sizing die set), or applications requiring a heavy crimp (which requires an auxiliary crimping die).
