Redding’s 0.225″ Steel Neck Bushing (part number 73225) is a precision reloading component designed for custom neck sizing. Heat treated steel with hand-polished sizing diameters and a surface hardness of Rc 60-62 reduces sizing effort, making it an excellent choice for reloaders seeking consistent, repeatable results without excessive sizing pressure.
These bushings feature external dimensions of 1/2″ O.D. by 3/8″ long and freely interchange in all Redding Bushing style Neck Sizing Dies. By selecting the correct bushing, you can provide just the right amount of neck tension to properly hold the bullet without excessive resizing. To determine the proper bushing size, measure the outside neck diameter of your loaded cartridges with a precision micrometer or dial caliper, then subtract .001″ from the cartridge that had the smallest average neck diameter—this diameter bushing will generally size case necks just enough to create the proper press fit for the bullet.
