Redding .331-inch Neck Sizing Bushing

The Redding .331-inch Neck Sizing Bushing (Redding part no. 76331) gives handloaders a way to size case necks to one exact, repeatable diameter instead of leaving neck tension to a fixed expander. Bushing dies let a reloader match neck tension to a specific brass lot, bullet jacket, or accuracy goal by simply changing bushings rather than dies. Redding builds this bushing across a wide diameter spread to cover cartridges from small-bore varmint rounds to large magnums. It is made to drop into any Redding bushing-style die already on the bench.

Key Specifications

• Bushing diameter is .331-inch, machined to size the case neck to that exact outside dimension.
• Body material is heat-treated steel, chosen for dimensional stability under repeated sizing strokes.
• Bushing surface carries a titanium nitride coating that increases surface hardness and cuts friction during sizing.
• Sold as a single bushing, letting you build a bushing set tailored to your own brass and bullet combination.
• Shipping weight is approximately 0.019 lb, reflecting its small, compact size.
• This bushing belongs to Redding’s neck-sizing bushing line, which spans roughly .17 to .338 caliber, letting you assemble a matched set across calibers.

Frequently Asked Questions

Does this bushing fit any sizing die? It is built to fit Redding bushing-style sizing dies, which accept interchangeable bushings so you can match neck tension to your specific brass and bullet combination.

Why use a bushing instead of a standard expander? A bushing sizes the neck to one fixed, repeatable diameter in a single pass, giving more direct control over bullet tension than a fixed expander ball provides.
