Can I use the RCBS R9803 .226 unit for standard .223 Remington or .22-250 Rem reloading?

No, this unit is explicitly designed with a .226-inch expander button for .22 Savage High-Power rifle brass and will excessively expand standard .22-calibre bottleneck cartridges like .223 Rem, .22-250 Rem, .22 Hornet, or .220 Swift. Standard .22-calibre cartridges require the RCBS #9802 unit instead to maintain correct neck tension.

What is the correct setup measurement for the decapping pin protrusion during installation?

Manufacturer instructions specify installing the unit into your sizing die with approximately 3/16 inch (4.76 mm) of the decapping pin protruding from the bottom of the die. This precise adjustment ensures reliable spent Boxer primer ejection without risking contact with the base of the case web.

Does this RCBS expander-decapping unit require any special electrical compliance or Australian certifications?

No electrical compliance or SAA/RCM certifications are required because the RCBS Expander-Decapping Unit is an unpowered, purely mechanical reloading die component. It is fully compliant for legal sale and distribution across all Australian states and territories for your reloading bench.

Is the RCBS R9803 compatible with Berdan-primed military surplus brass?

No, this unit is designed strictly for Boxer-primed bottleneck brass cases featuring a single central flash hole. Using it on Berdan-primed brass lacks the correct priming structure and will result in a broken decapping pin.

RCBS R9803 Expander Decapping Unit - RCBS R9803

The RCBS Expander-Decapping Unit .226 (RCBS SKU 9803) is a precision-machined steel replacement assembly designed for standard RCBS bottleneck rifle sizing dies. This unpowered mechanical tool component performs two critical steps during the reloading cycle: ejecting spent Boxer primers via a hardened, headed decapping pin, and expanding the case mouth to correct internal dimensions using an integrated .226-inch expander button on the press downstroke. It maintains neck concentricity and aligns brass cases accurately, serving as an exact replacement for worn, bent, or damaged factory decapping rods.

Key Features

Dual-Action Processing: Simultaneously de-primes Boxer-primed cartridge cases and expands case necks to proper interior diameter during resizing.
Calibre-Specific .226 Button: Fitted with a precision-machined .226-inch expander ball designed specifically for firearms chambered in .22 Savage High-Power (5.6×52mmR) that shoot nominal .227 to .228-inch projectiles.
All-Steel Construction: Threaded steel expander rod with a headed decapping pin and locking mechanism ensures straight alignment and minimises neck runout.
Drop-In Compatibility: Installs directly into standard-length RCBS bottleneck rifle dies with a total packaged weight under 50 g.

Who is the RCBS Expander Decapping Unit .226 for?

Reloaders loading .22 Savage High-Power ammunition — requires the .226-inch expander button to properly resize case mouths for .227 to .228-inch bullets while maintaining a 3/16 inch (~4.76 mm) decapping pin protrusion to reliably eject spent primers without bottoming out in the case web.

Less suitable for: Reloaders processing standard .22-calibre bottleneck cartridges (such as .223 Rem, .22-250 Rem, .22 Hornet, or .220 Swift), which require a dedicated .223-calibre / 5.56mm expander-decapping unit to avoid over-expanding case necks, or anyone processing Berdan-primed brass, which lacks a central flash hole and will bend or break standard decapping pins.
