Redding .303-inch Neck Sizing Bushing

Precision rifle handloaders reach for a Redding .303-inch Neck Sizing Bushing (Redding part no. 76303) when they want to control case-neck tension independently of the rest of the sizing operation. Instead of a fixed expander ball setting neck diameter for every case regardless of brass thickness, a bushing sizes the neck to one specific, repeatable diameter. Redding manufactures this bushing line across a long run of sizes to match different brass and bullet jacket combinations. It fits directly into a Redding bushing-style sizing die already set up on the press.

Key Specifications

• Bushing diameter is .303-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

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.

Is this bushing sold as a single piece? Yes, this listing is for one .303-inch bushing; Redding sells the line across dozens of individual diameters so you can order exactly the size your load requires.
