The Redding 22 Cal. Carbide Size Button Kit (MPN: 48223) upgrades Redding reloading dies by replacing standard steel expander buttons with an ultra-smooth, free-floating solid carbide expander. Engineered for standard .22-calibre bottleneck rifle cases, this kit expands case necks without requiring inside-neck lubrication. The free-floating design allows the carbide button to self-center within the case neck during the press stroke, minimising neck runout and brass stretching to prolong cartridge case life.

Key Features

• Lube-Free Neck Expanding: Low-friction solid carbide construction eliminates the need to apply inside-neck case lubricant, preventing powder contamination and removing secondary case-cleaning steps.
• Free-Floating Action: Floats on the decapper rod to self-center naturally within the case neck, reducing case neck runout and brass distortion.
• Reduced Brass Fatigue: Low friction reduces drag as the expander button exits the case neck, decreasing neck stretch on the downstroke.
• Die Compatibility: Fits Redding standard Full Length Sizing Dies, Neck Sizing Dies, and Type-S Bushing Sizing Dies.

Who is the Redding 22 Cal. Carbide Size Button Kit for?

• Precision benchrest handloaders loading .223 Remington and .22-250 Remington — Seeking uniform neck tension and minimal runout for .22 Calibre / 5.56 mm bottleneck rifle cartridges, this carbide neck sizing button kit uses a self-centering, free-floating carbide assembly to reduce neck distortion without lube.
• High-volume varmint and pest control reloaders — Loading large quantities of .22 Calibre / 5.56 mm ammunition benefit from this carbide neck sizing button kit because its low-friction carbide surface eliminates inside-neck lubing steps and reduces neck stretch during continuous reloading sessions.

Less suitable for: Handloaders sizing cartridges outside the .22 Calibre / 5.56 mm threshold (such as .20 cal, 6 mm, 6.5 mm, or .30 cal), which require a dedicated calibre-matched carbide button kit, or reloaders using Redding Competition Bushing Neck Sizing Dies, which require dedicated micrometer-stem button conversion assemblies.
