RCBS Coated Neck Bushings are interchangeable to let the reloader select a bushing that gives precisely the right amount of tension on the bullet when using RCBS Gold Medal Match neck sizing dies. These bushings have a Tungsten Disulfide (WS2) anti-friction coating, so they do not require use to traditional case lube. Self-centering for proper alignment with case neck For best results, use of high-end brass with consistent neck thicknesses For use ONLY with RCBS Gold Medal neck sizing dies RCBS recommends having neck bushings one to two sizes above and below your target diameter (see note below). RCBS Coated Neck Bushings are a small but critical component in loading extremely consistent-shooting ammo with your Gold Medal Match sizing dies. Brownells Gun Tech™ Tip: There are two ways to select the steel neck bushings you need: (1) Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003". This allows approximately .001" of brass to spring back for correct neck tension. (2) You can also measure the neck wall thickness of your case, multiply by two, add the diameter of your bullet and subtract .002" to .003".
