The Redding .242 Titanium Nitride Neck Sizing Bushing (MPN 76242) is a precision reloading component engineered to size the external neck of cartridge cases down to a 0.242-inch inside diameter. Manufactured with a heat-treated steel base hardened to Rc 60–62 and coated with a Titanium Nitride (TiN) surface treatment, this bushing reduces sizing friction and minimises the risk of brass galling. Designed to freely float inside compatible dies, it features a self-centring internal lead-in radius that accurately aligns with the case neck to control neck tension without overworking the brass or requiring an internal expander ball.

Key Features

• Titanium Nitride Coating: Features a micro-smooth TiN surface over an Rc 60–62 hardened steel base to resist surface wear and lower operating friction during sizing passes.
• Self-Centring Design: Built with an internal lead-in radius that allows the bushing to float and self-align over the cartridge neck within compatible sizing dies.
• Expander-Free Sizing: Resizes case necks to an exact 0.242-inch diameter without the use of an expander ball, preventing brass stretching and extending case life.
• Standard Die Compatibility: Fits all standard Redding Bushing-style Neck Sizing Dies, Type S Full Length Dies, Competition Neck Sizing Dies, and dimensionally interchangeable L.E. Wilson style neck dies.

Who is the Redding .242 Titanium Nitride Neck Sizing Bushing for?

• Australian precision rifle shooters reloading .22 calibre cartridges — Requires exact bullet retention across cartridges like .223 Remington or .222 Remington, utilising this neck sizing bushing's 0.242-inch inside diameter to establish uniform neck tension on cases measuring approximately 0.243 inches when loaded.
• Benchrest competitors adjusting case neck tension — Benefits from the Rc 60–62 hardened steel core and low-friction TiN surface treatment of this titanium nitride neck sizing bushing, which prevents case galling and maintains dimensional concentricity across standard 0.500-inch outside diameter die channels.
• Varmint hunters reloading small-bore cartridges — Needs consistent sizing cycles for small-bore brass without overworking case necks, relying on the 0.242-inch sizing diameter and 0.375-inch height profile to size brass without requiring an internal expander ball.

Less suitable for: Handloaders processing brass where neck wall thickness varies by more than 0.002 inches or where loaded case necks do not measure approximately 0.243 inches; these applications require neck-turning tools or an alternative diameter bushing chosen from Redding's 0.185-inch to 0.368-inch sizing range.
