If you're running a bushing-style neck sizing die and chasing that last bit of consistency, Redding's .288" Titanium Nitride bushing is one of the simplest upgrades you can make. It lets you fine-tune neck tension to match your brass and your load instead of relying on whatever a standard die hands you, which is a big deal when you're trying to tighten up groups and keep your runout in check.
The body is heat-treated steel, hand polished to a surface hardness of Rc 60-62, then finished with a titanium nitride coating that bumps up the effective surface hardness and cuts down on sizing friction. In plain terms, the brass glides through easier and the bushing shrugs off wear over the long haul. With the case neck lightly lubed, it won't leave marks on your necks, which keeps things clean and consistent.
These are sold in .001" increments across the .185" to .368" range, covering calibers from .17 through .338, and every bushing is clearly marked with its size on the ID for quick identification at the bench. To land on the correct size, measure the outside neck diameter of a loaded cartridge with a precision micrometer, then subtract .001" to .002" to account for brass spring-back and the tension you want on the bullet.
The .288" bushing shares the standard 1/2" O.D. x 3/8" long dimensions, so it drops right into any Redding bushing-style sizing die and interchanges with L.E. Wilson style bushings as well. It's made in the USA and built to hold up through thousands of cycles, making it a dependable piece of kit for precision handloaders who care about repeatable bullet retention without overworking the case neck.
Measure the outside neck diameter of a loaded cartridge with a precision micrometer, then subtract .001" to .002" from that number. The subtraction accounts for brass spring-back and gives you the neck tension to hold the bullet securely. That result points you to the right bushing, so the .288" works out for loads measuring roughly .289" to .290" at the loaded neck.
The .288" bushing uses the standard 1/2" O.D. x 3/8" long dimensions, so it drops into any Redding bushing-style neck sizing die. It also interchanges with L.E. Wilson style bushings. Keep in mind the die itself is sold separately.
Both styles start with the same heat-treated steel body, but the titanium nitride coating increases the effective surface hardness and reduces sizing friction. That means brass slides through easier and the bushing holds up longer over many sizing cycles. With a lightly lubed neck, it also won't leave marks on your brass.
Picking the exact bushing for your brass lets you set just enough neck tension to hold the bullet without over-resizing. Less working of the brass means more consistent neck tension and less runout, which can translate to tighter groups. It's a popular move among precision handloaders for exactly that reason.
