What specific size range does the Redding 19223 tapered size button cover?

The Redding 19223 model is precision-machined to gradually expand cartridge case necks starting specifically from .17 calibre up to standard .22 calibre, resulting in a .224 inch bullet diameter. For expanding cases beyond .22 calibre into 6mm, 6.5mm, 7mm, or .30 cal, distinct dedicated calibre-specific tapered expander buttons must be used instead.

Which reloading dies are compatible with the Redding Tapered Size Button From 17 To 22 Cal?

This expander button is designed to thread onto Redding decapping rod assemblies within Redding Full-Length Sizing Dies, Neck Sizing Dies, and Type S Bushing Sizing Dies. Note that it is not natively threaded for other brands such as Lee, Hornady, or RCBS without custom decapping rod adapters, and the decapping rod assembly itself is sold separately.

Are there any special lubrication requirements when performing high-expansion passes with this tool in Australian reloading environments?

Yes, because of the demanding nature of necking up brass, it requires proper case neck lubrication inside the case mouth during high-expansion passes to prevent brass galling or rod deformation. Pairing this step with high-quality lubricants like Redding Imperial Sizing Die Wax helps ensure smooth operation on your reloading bench.

Does this manual reloading accessory require any electrical compliance marks for use in Australia?

No electrical or compliance requirements apply to this item because it is an entirely manual, non-powered reloading accessory. It is an unrestricted reloading component across all Australian states and territories, meaning AS/NZS electrical standards, RCM marks, and 240V compatibility are completely not applicable.

Tapered Size Button - Redding 19223

Built for handloaders reforming brass or converting parent cases, this expander button features a smooth, gradual taper that steps neck internal diameters from .17 calibre up to standard .22 calibre (.224" bullet diameter) without causing excessive neck stretching, shoulder collapse, or brass distortion.

Who is the Redding Tapered Size Button From 17 To 22 Cal for?

Handloaders necking up .17 calibre parent cases to .22 calibre wildcats — provides a continuous, gradual taper designed to open case necks from .17 calibre up to the .224" bullet diameter standard without crushing thin-walled case shoulders.
Reloaders replacing standard elliptical buttons in compatible Redding sizing dies — installs directly onto existing Redding decapping rod assemblies with an ultra-lightweight profile under 36 g (0.08 lbs) to reduce friction and neck runout during the sizing stroke.

Less suitable for: Handloaders expanding cases beyond .22 calibre to 6mm, 6.5mm, 7mm, or .30 calibre, who require dedicated larger-calibre tapered expander buttons; and reloaders using non-Redding dies without custom decapping rod adapters.
