Which Redding dies are compatible with the 16356 tapered size button?

The Redding 16356 tapered size button is designed to screw directly onto the decapping rod assembly inside Redding Standard Full-Length and Neck Sizing Dies, as well as Type "S" Bushing Dies. It is specifically engineered to interface with bottleneck rifle cases like the .35 Whelen and .358 Winchester.

Can I use this button to expand brass starting from .22 or 6mm up to .35 calibre in a single step?

No, you should not attempt to jump straight from sub-7mm bores like .22 or 6mm up to .35 calibre with this button, as doing so can crush or buckle the case shoulder. This specific model is strictly designed to start expanding from a minimum inside neck diameter of 7mm (.284") up to .35 calibre (.358"); smaller bores require intermediate step expanders.

Does the Redding 16356 require any electrical safety compliance or SAA/RCM certification for use in Australian workshops?

No electrical compliance or SAA/RCM certification is required for this product. The Redding 16356 is a fully mechanical, manual reloading accessory containing no electrical components, plugs, or batteries, making it safe and legal for setup on any Australian reloading bench.

What case lube is recommended when operating this steel tapered size button to prevent galling during wildcatting?

Because this precision-machined, heat-treated steel button experiences friction when opening up case necks, you should always apply a quality case lubricant such as Redding Imperial Sizing Die Wax before running donor brass through your press. Proper lubrication ensures smooth neck expansion without tearing or stretching the brass.

Tapered Size Button - Redding 16356

The Redding Tapered Size Button From 7mm To 35 Cal is a precision-machined, heat-treated steel reloading component designed to expand bottleneck rifle case necks smoothly during the sizing operation. Engineered to fit Redding standard full-length, neck sizing, and Type "S" bushing dies, it threads directly onto the standard decapping rod assembly. Its elongated taper profile allows reloaders to open undersized cartridge case necks from an initial 7mm (.284") internal diameter up to a nominal .35 calibre (.358") internal diameter without stretching, buckling, or tearing case shoulders.

Key Features

Gentle Neck Expansion: Utilises an elongated taper profile to transition case mouth diameters from 7mm up to .35 calibre smoothly in a controlled sizing pass.
Direct Die Integration: Screws directly onto the decapping rod assembly of Redding standard conventional dies and Type "S" bushing dies.
Durable Steel Construction: Precision-machined from heat-treated steel to maintain profile integrity during repetitive case forming.
Mechanical Operation: Fully manual reloading component requiring no external power or electrical connection.

Who is the Redding Tapered Size Button From 7mm To 35 Cal for?

Reloaders of .35 Whelen and .358 Winchester Cartridges — provides the precise 7mm to .35 calibre taper required to expand factory or parent brass up to .358" inside neck diameter without buckling case shoulders.
Wildcat Cartridge Developers — expands donor brass starting at 7mm (.284") or .30 calibre (.308") directly up to .35 calibre using a compact 0.08 lbs tapered size button installed in standard sizing dies.

Less suitable for: Reloaders forming brass from parent calibres smaller than 7mm (such as 6mm or .22 calibre), who require intermediate step expanders or smaller-calibre tapered expanders to prevent crushing the case neck and shoulder.
