Redding 73 Style Steel Neck Sizing Bushing .248 – 73248

Description

This is the Redding 73 Style Steel Bushing in a .248" diameter, the little part that gives serious handloaders real control over neck tension. Instead of oversizing your case necks and overworking the brass, you pick the exact bushing that sizes the neck just enough to hold the bullet securely. The result is brass that lasts longer, runout that stays tight, and ammo that groups the way you want it to.

The bushing is made from heat treated steel, and the sizing diameter is hand-polished to a surface hardness of Rc 60-62. That polished, hardened surface is what makes the case neck slide through with less effort and less drag, which matters when you are running a lot of brass through a press. Every bushing measures 1/2" O.D. by 3/8" long and is clearly marked with its size, so there is no guessing which one is in your die.

Why the .248 Redding Steel Bushing Matters for Neck Tension

Bushing dies only work as well as the bushing you feed them. By choosing the right size, you set just the right amount of grip on the bullet without squeezing the neck down more than necessary. A common way to find your number is to measure the outside neck diameter of a loaded round with a precision micrometer, then subtract about .001" to account for brass spring-back and the tension needed to hold the bullet. If you are loading moly-coated bullets, some folks step down an extra .001" or .002" for a slightly tighter neck.

Fitment for the Redding 73 Style Steel Bushing

These bushings freely interchange across all Redding bushing-style neck sizing dies, including the Type S and Competition dies. The full lineup runs in .001" increments from .185" through .368", covering everything from .17 caliber up through .338, so this .248" is one size in a very deep range. It is made in the USA and shares the same external dimensions as the rest of the family, so swapping sizes is quick when you change loads or chambers.
