Does the Redding 221 Remington Fireball Neck Sizing Die (Part 81101) come with a shellholder, or do I need to purchase one separately?

The die requires a standard Redding #10 Shellholder (Part #11010) or Competition Shellholder (Part #11610), which are sold separately. It does, however, include a standard lock ring, decapping rod assembly, steel size button, and replaceable decapping pin in the box.

Can I use this neck sizing die for .221 Fireball brass that I plan to shoot out of a semi-automatic or lever-action rifle?

No. This neck sizing die is designed exclusively for brass that will be re-fired in the exact same bolt-action or single-shot firearm. For semi-automatics, lever actions, or pump actions, neck-sized brass can cause chambering and extraction failures, meaning a full-length sizing die is strictly required.

What should I do if my bolt closure becomes stiff after reloading my .221 Remington Fireball brass 3 to 5 times with this die?

Over 3 to 5 reload cycles, case shoulders naturally migrate forward and the body can experience tight chambering. Because the #81101 die only sizes the neck and leaves the body and shoulder undisturbed, you will need to incorporate a Redding body die or switch to a full-length sizing die once shoulder growth occurs.

Are there any Australian electrical or RCM compliance certifications required to operate this Redding reloading die?

No. The Redding 221 Remington Fireball Neck Sizing Die is a purely mechanical reloading tool that operates without electricity. Therefore, electrical compliance ratings like 240V mains compatibility, AS/NZS electrical approvals, and RCM or SAA certifications are completely non-applicable.

Neck Sizing Die - Redding 81101

The Redding 221 Remington Fireball Neck Sizing Die (Part #81101) is a dedicated, non-bushing reloading tool designed to resize only the neck of .221 Remington Fireball cartridge brass. By maintaining the fire-formed dimensions of the case body and shoulder from the host firearm, this die minimises brass work-hardening, extends overall case life, and promotes concentric chamber alignment. It integrates an internal decapping assembly with a steel expander button to unseat spent primers and expand internal neck diameters for .224" bullets in a single press stroke.

Key Features

Targeted Neck Resizing: Resizes only the case neck while leaving the fire-formed case body and shoulder untouched for tighter chamber fitment.
Extended Case Longevity: Prevents over-working of brass sidewalls, eliminating unnecessary material stress on .221 Fireball cartridge cases.
Integrated Decapping & Expanding: Features a steel size button (#39223) and replaceable decapping pin (#01060) to decap spent primers and set internal neck tension for .224" diameter projectiles.
Universal Press Mounting: Features standard 7/8"-14 TPI external threads compatible with standard single-stage and turret reloading presses.

Who is the Redding 221 Remington Fireball Neck Sizing Die for?

Precision handloaders shooting .221 Remington Fireball bolt-action rifles — sizes only the neck of brass fired in dedicated bolt-action chambers, utilising a 7/8"-14 TPI mounting thread to fit standard reloading presses while preserving custom fire-formed dimensions for consistent cartridge alignment.
Varmint hunters seeking enhanced bullet concentricity and accuracy — sets correct neck tension for standard .224" diameter projectiles in .221 Remington Fireball brass without working the body or shoulder, prolonging brass life across repeated field loads.

Less suitable for: Cartridges fired across multiple different firearms, brass intended for semi-automatic, pump, or lever-action actions, or cases that have developed tight chambering and shoulder growth after 3 to 5 reload cycles; these applications require a full-length sizing die or a dedicated body die to restore factory SAAMI body and shoulder specifications.
