This is the Redding 73 Style Steel Neck Sizing Bushing in a .265 diameter, part number 73265. If you shoot a bushing-style neck die, these are the little parts that do the heavy lifting on your neck tension, and getting the right one makes a real difference in how your ammo holds the bullet and how long your brass lasts.
Neck sizing bushings let you size only part of the neck to the exact diameter you want instead of over-working it with a standard one-size expander setup. By picking the correct bushing, you set just the right amount of neck tension to hold the bullet without squeezing the brass more than it needs. Less sizing means straighter necks, less runout, and brass that survives more firings before the necks start giving out. The .265 covers a popular spot in the 6mm, 25, and 6.5mm range, so it fits a lot of common precision cartridges.
This is a heat-treated steel bushing with the sizing diameter hand polished to a surface hardness of Rc 60-62, which cuts down the effort it takes to push the neck through. Redding makes these across the range of .185 through .368 in .001 inch steps, and the last three digits of the part number spell out the size, so 73265 is your .265. With the neck lubed, a clean steel bushing like this one leaves your necks mark-free. It's self-centering inside the die, which keeps the sizing even all the way around.
The simplest way to find your number is to measure the outside neck diameter of a loaded or dummy round with a micrometer or good caliper, then subtract about .001 to .002 inch for spring-back and bullet grip. If you don't have a loaded round handy, measure your case neck wall thickness, double it, add your bullet diameter, then subtract to land on the bushing size. Many reloaders keep a couple of neighboring sizes on hand so they can tune tension up or down a thousandth at a time until the load shoots the way they want. Made in the USA.
Yes. Redding 73 style steel bushings freely interchange in all Redding bushing-style neck sizing dies. They also interchange with L.E. Wilson style bushings, so they'll work in a lot of setups beyond just Redding bodies.
Measure the outside neck diameter of a loaded or dummy round with a micrometer, then subtract about .001 to .002 inch for spring-back and bullet grip. If the result lands near .265, this is your bushing. If you don't have a loaded round, measure your neck wall thickness, double it, add your bullet diameter, then subtract to find the number.
This is the heat-treated steel version, hand polished to Rc 60-62 hardness to reduce sizing effort. The titanium nitride bushings add a surface coating that hardens the face further and cuts friction even more. Both size the neck to the same marked diameter, so the choice comes down to how slick you want the sizing to feel.
Not when used right. With the case neck lubed, a clean steel bushing leaves no marks on the necks. The sizing diameter is hand polished, and the bushing self-centers in the die to keep the sizing even all the way around.
