The Redding .333-inch Steel Neck Sizing Bushing (Redding part no. 73333) is a genuine Redding 73-style steel bushing sized to control cartridge neck diameter to .333 inch. Redding pioneered the interchangeable-bushing neck sizing system, and this bushing is the precision component handloaders swap into the die to dial in exact neck tension for a given brass thickness and bullet fit. It’s built for bench-rest and precision rifle shooters who tune neck tension rather than rely on a fixed one-size sizing die. Because the bushing itself sets the sizing diameter, one die body can serve multiple neck-tension setups just by changing bushings.

Key Specifications

• Sizes cartridge necks to .333 inch, the exact diameter that sets neck tension on the loaded round.

• Built to the 73-style bushing profile, so it drops straight into a Redding-style bushing neck sizing die body.
• Lets handloaders swap bushings to change neck tension without buying a new die for every tension setup.
