The Redding Competition Standard Seating Stem Long 6.5mm (MPN: 55046) is a precision-machined internal seating plug designed specifically for Redding Competition Bullet Seating Dies. Measuring 30.16 mm (1-3/16 inches) in length, this extended-format stem interfaces directly with the die's floating sleeve system to maintain straight-line alignment when seating 6.5mm (.264 calibre) projectiles. It features a standard-profile internal cup contour engineered to contact traditional tangent ogives, ensuring consistent seating depth and minimal bullet runout across medium-to-long bottleneck cases such as the 6.5 Creedmoor, .260 Remington, and .260 Rem Ackley Improved.

Key Features

  • Precision Alignment: Integrates with Redding's floating sleeve competition seating dies to deliver straight-line projectile guidance and factory-spec concentricity.
  • Standard Ogive Geometry: Engineered with a standard internal cup profile to correctly seat traditional spitzers and standard tangent-ogive target and hunting bullets.
  • Long-Format Dimension: Measures 30.16 mm (1-3/16 inches) to accommodate specific long-format 6.5mm cartridge setups within modern Redding competition seating die bodies.
  • OEM Replacement: Serves as a direct-fit maintenance or replacement component for lost, worn, or modified original standard 6.5mm competition seating stems.

Who is the Redding Competition Standard Seating Stem Long 6.5mm for?

  • Precision Rifle Competitors (PRS / F-Class) — seats .264 calibre projectiles with uniform concentricity in Redding Competition Seating Dies using a 30.16 mm long floating stem configured for straight-line alignment.
  • Handloaders Loading Standard-Profile Bullets — matches conventional 6.5mm tangent ogives and spitzer hunting bullets via a factory-contoured standard cup profile to prevent ogive deformation during medium-to-long case neck insertion.

Less suitable for: Handloaders seating long polymer-tipped or secant-ogive Very Low Drag bullets, where standard cup geometries can bottom out on delicate tips; a dedicated deep-cut VLD profile seating stem is required instead. Additionally, it will not seat inside older-generation Redding competition dies limited to 25.4 mm (1 inch) stems, nor standard non-micrometer reloading dies lacking compatible floating-stem housings.
