Will the Redding 17 Hornet Body Die also resize the case neck or decap primers?

No, this is specifically a body die designed to resize the case body and bump the shoulder back to SAAMI specifications without touching the case neck. It contains no internal expander ball or decapping rod, meaning it should be used alongside a separate neck-sizing die like the Redding Type S Bushing Neck Die to preserve neck concentricity.

Is the Redding 75279 body die compatible with my standard Australian reloading press?

Yes, the die features a standard 7/8"-14 thread that is fully compatible with all popular single-stage and turret reloading presses used in Australia, including models from Redding, RCBS, Hornady, Lyman, and Lee. You will also need to pair it with a Redding Shellholder #14, which is sold separately.

Can I use this body die for .17 Ackley Hornet brass as well as standard .17 Hornet?

No, this die is strictly engineered for standard .17 Hornet cartridges with a bullet diameter of .172". It is incompatible with wildcat cartridges or alternate chambers like the .17 Ackley Hornet, which feature different shoulder angles and require dedicated custom dies.

How should I maintain this heat-treated steel die to prevent rust in humid Australian conditions?

Because the die is precision-machined from heat-treated alloy steel with a polished interior, it is recommended to apply a light coat of rust-preventative gun oil for storage in humid coastal or outback environments. Always ensure cases are properly lubricated before sizing to prevent stuck cases, and wipe down the interior thoroughly before reloading sessions.

17 Hornet Body Die - Redding 75279

The Redding 17 Hornet Body Die (MPN: 75279) is a dedicated reloading tool designed to full-length resize the case body and bump the shoulder back to SAAMI factory specifications without contacting the case neck. Engineered without an internal expander ball or decapping rod assembly, it eliminates neck friction and preserves concentricity on delicate .17-calibre brass. Precision-machined from heat-treated alloy steel with a polished interior, this die restores easy chambering for cases fired repeatedly in bolt-action rifles without overworking the neck area.

Key Features

Neck-Free Body Sizing: Resizes the cartridge body and bumps the shoulder back to chamber dimensions while leaving the neck untouched.
No Internal Friction: Features an open interior with no decapping pin or expander ball, preventing neck runout and stretching.
Precision Steel Construction: Machined from heat-treated alloy steel with polished internal surfaces to reduce sizing resistance and prevent case binding when used with standard case lubricant.
Universal Press Threading: Uses standard 7/8"-14 threading for direct integration into single-stage and turret reloading presses.

Who is the Redding 17 Hornet Body Die for?

Precision Bolt-Action Handloaders — requires dedicated body sizing for delicate .172" bullet diameter brass to restore easy bolt closure after repeated firings without overworking the case necks.
Bushing Die Reloaders — pairs with standard 7/8"-14 thread neck-sizing setups to bump shoulders back to factory headspace dimensions while maintaining isolated neck tension control.

Less suitable for: Wildcat cartridge shooters using modified chambers such as the .17 Ackley Hornet, which require dedicated wildcat full-length or neck-sizing dies with matching shoulder angles; and reloaders needing single-step depriming and neck sizing, who require a standard full-length sizing die with an integrated decapping assembly.
