Redding .251″ Titanium Nitride Neck Sizing Bushing 76251

Description

Precision handloaders know that neck tension is one of the biggest levers you can pull for consistent groups, and that is exactly what a bushing like this .251" Redding Titanium Nitride piece lets you control. Rather than oversizing the neck and springing it back open, you pick the bushing that works your brass just enough to hold the bullet right. This one measures .251" and carries Redding's part number 76251.

What the TiN Coating Brings to the .251 Bushing

Redding starts with heat treated steel and hand polishes the sizing diameter to a hardness around Rc 60 to 62, then adds a titanium nitride surface treatment that pushes the effective hardness even higher and cuts down sizing friction. In plain terms, the stroke feels smoother and the bushing holds its dimension through a lot of cases. With the neck properly lubed, it slides over the brass without leaving marks on the necks, which is what you want when you are chasing accuracy.

Fit and Compatibility of the Redding 76251

These neck sizing bushings freely interchange across Redding's bushing style dies, including the Type S Full and Neck Sizing dies, and they also drop into Wilson style bushing setups. The bushing itself follows Redding's standard dimensions of 1/2" outside diameter by 3/8" long, and the size is marked right on it so you always know which one you have grabbed from the drawer. Redding offers the full range in .001" steps, so once you know your target you can land right on it.

Picking the Right Size

To figure out which bushing you need, measure the outside neck diameter of a loaded round with a good micrometer, then subtract about .001" to .002" to account for brass spring back and give you proper bullet grip. That math points you straight to the number. This .251" option lands in the range that works well for a number of 25 caliber and similar neck setups. Made in the USA, it is a small part that makes a real difference on the bench.
