Will the Redding 49307 Carbide Size Button Kit fit my non-Redding reloading dies like RCBS or Hornady?

No, this kit is specifically designed for Redding decapping rod assemblies. It will not drop into non-Redding dies without custom decapping rod modifications due to differing rod thread pitches and stem diameters.

Can I use this carbide size button kit with Redding Competition Bushing Neck Sizing Dies?

No, the 49307 kit is incompatible with Competition Bushing Neck Sizing Dies. It is engineered specifically to fit standard Redding bottleneck sizing dies and Type-S Bushing Dies.

Do I still need to use case neck lube when resizing .30 caliber brass with this carbide kit?

One of the primary benefits of the polished tungsten carbide button is that it eliminates the absolute requirement for inside-neck lubrication. This speeds up your reloading workflow and prevents powder contamination from residual lubricants.

Do I need a firearms license or special permit to purchase this reloading accessory in Australia?

No, the Redding 49307 kit is an un-serialized mechanical reloading component. It does not require a firearms license or police permit to purchase or ship across Australian states and territories.

What components are included in the Redding 49307 package?

Each kit includes one 0.308 inch solid tungsten carbide expander sizing button, a retainer sleeve or mounting hardware, and a spare decapping pin. Everything required for a seamless upgrade to your standard Redding decapping assembly is provided.

Carbide Size Button Kit - Redding 49307

The Redding Carbide Size Button Kit – .30 Caliber / 7.62mm (MPN 49307) is a drop-in reloading upgrade designed to replace standard steel expander buttons on Redding bottleneck rifle sizing dies. Engineered from solid tungsten carbide, this expander button features a free-floating design that self-centres inside the cartridge case neck during the sizing stroke. By dramatically reducing friction, it minimises case neck runout and brass stretch while removing the need to apply and subsequently clean inside-neck lubricant during reloading workflows.

Key Features

Solid Tungsten Carbide Construction: The ultra-hard, low-friction carbide surface glides through case necks smoothly, eliminating the requirement for inside-neck lubrication and preventing powder contamination.
Free-Floating Assembly: Mounts loosely on the decapping rod to self-centre within the case neck as it expands, reducing neck runout and brass stretching.
Bottleneck Cartridge Compatibility: Sized specifically for .30 caliber / 7.62mm bottleneck cases, including .308 Winchester, .30-06 Springfield, .300 Win Mag, and .300 WSM.
Comprehensive Hardware Kit: Ships complete with the .30 cal carbide button, retainer sleeve mounting hardware, and a spare decapping pin.

Who is the Redding Carbide Size Button Kit for .30 Cal for?

Precision rifle reloaders loading .30 caliber bottleneck cartridges — needs a carbide expander button ground to a 0.308 inch expander diameter that fits standard Redding bottleneck sizing dies and Type-S Bushing Dies to streamline high-volume brass preparation without requiring inside-neck lube.
