RCBS Steel Neck Bushings are designed to offer reloaders the opportunity to choose the appropriate bushing that provides ideal tension on the bullet when using the RCBS Gold Medal Match sizing dies. Such precision fitting reduces the work hardening of the case neck brass, which in turn extends the life of the case, and improves accuracy.

These bushings come in bare steel which means that traditional case lubrication is necessary for optimal results. It's crucial to note that the use of high-end brass with consistent neck thickness is recommended. RCBS also recommends having neck bushings that are one to two sizes above and below your target diameter.

To select the appropriate steel neck bushing, you can use one of the two methods below. First, measure your loaded cartridge's outside neck diameter, then subtract between .002" to .003". This allows approximately .001" of brass to spring back for correct neck tension. Alternatively, you can measure the neck wall thickness of your case, multiply by two, add the diameter of your bullet and subtract .002" to .003".

It's essential to use these steel neck bushings only with RCBS Gold Medal sizing dies to achieve the best possible results. RCBS Steel Neck Bushings are a crucial component that helps you load consistent shooting ammo with your Gold Medal Match sizing dies.
