The Redding 73 Style Steel Bushing/.363 (Mfr. Part 73363) is a precision neck sizing tool for discerning reloaders. Made of heat-treated steel with sizing diameters hand-polished to a surface hardness of Rc 60-62, this bushing delivers reduced sizing effort and consistent performance across repeated reloading cycles. Redding Neck Sizer Bushings freely interchange in all Redding Bushing-Style Sizing Dies, offering seamless compatibility with your existing equipment.
Available throughout the range of .185″ through .368″ in .001″ increments, with the last three digits of the part number denoting bushing size, the .363″ diameter allows reloaders to achieve the precise neck tension essential for accuracy and bullet retention. To determine proper bushing size, measure the outside neck diameter of loaded cartridges with a precision micrometer, then subtract .001″ from the smallest average measurement—this diameter will generally size case necks just enough to create the proper press fit for the bullet. Whether you’re working with standard rifle loads or magnum cartridges, this versatile bushing integrates seamlessly into your reloading workflow.
