Will this RCBS 6.5mm expander decapping unit work with my 6.5 Creedmoor sizing die?

No, this specific model (R9807) is explicitly not for 6.5 Creedmoor sizing dies due to differing internal chamber geometry and rod lengths required for short-action configurations. It is designed for standard-length bottleneck 6.5mm / .264 calibre cartridges like the 6.5x55mm Swedish Mauser and .260 Remington.

What is the correct setup depth for the decapping pin during initial installation?

For proper operation during your reloading sessions, the decapping pin should be set to protrude approximately 3/16 of an inch (about 4.76 mm) below the base of the sizing die. Ensure you are using Boxer-primed brass, as Berdan-primed cases lack a single central flash hole and will break the steel decapping pin.

Does this mechanical reloading component require any electrical compliance certification for use in Australia?

As a purely mechanical tool machined from hardened steel, the RCBS R9807 requires no 240V power, Australian plugs, or SAA/RCM regulatory electrical certifications. Additionally, because it is a reloading accessory rather than a complete firearm, it does not require any special firearm registration permits for purchase or transport across Australian states and territories.

6.5mm Decapping Unit - RCBS R9807

The RCBS Expander Decapping Unit 6.5mm (Part #9807 / R9807) is a precision-machined hardened steel replacement assembly designed for standard RCBS bottleneck rifle sizing dies. This dual-function component decaps spent Boxer primers while expanding the internal neck diameter to .264 calibre during the reloading sizing stroke. Built with standard internal die threading and an approximate length of 10 to 12 cm, it maintains case concentricity and ensures uniform neck tension for proper bullet seating across compatible 6.5mm cartridges.

Key Features

Dual-Action Case Prep: Removes spent central Boxer primers using a replaceable steel decapping pin while simultaneously expanding the cartridge neck.
Calibre-Specific Geometry: Features an integrated .264 calibre expander ball tailored for standard-length 6.5mm bottleneck rifle cases.
Durable Hardened Steel Construction: Precision-machined to withstand repeated sizing friction with a total assembly weight of approximately 45 to 60 g.
Drop-In Die Compatibility: Threads directly into standard RCBS full-length and neck sizing dies as an exact factory replacement for bent or worn internal components.
Precise Setup Depth: Configured for standard factory positioning, allowing the decapping pin to protrude approximately 3/16 inch (~4.76 mm) below the base of the die.

Who is the RCBS Expander Decapping Unit 6.5mm Not For Creedmoor for?

Reloaders of standard-length 6.5mm bottleneck rifle cartridges — sizes case necks to exact .264 calibre internal dimensions on standard-length bottleneck brass such as 6.5x55mm Swedish Mauser, .260 Remington, and .264 Winchester Magnum using this dedicated sizing die expander decapping unit.
Reloaders replacing damaged or worn RCBS sizing die components — restores original factory function using standard internal die threading and a decapping pin set to the factory-standard 4.76 mm (~3/16 inch) protrusion depth to replace bent expander rods without purchasing an entirely new die set.

Less suitable for: Reloaders working with 6.5 Creedmoor cartridge dies that require dedicated short-action internal geometry, reloaders processing Berdan-primed cases without a central flash hole, or precision target shooters requiring zero neck-drag expansion who are better served by a dedicated neck-mandrel expander die or bushing sizing die system.
