RCBS Standard Die Set Features The RCBS Standard Die Set is built around a Full-Length Sizer Die that resizes the outside of fired bottleneck cases de-primes the spent primer and expands the case neck to accept a new bullet in a single pass. Vent holes in the die release trapped air and excess lubricant preventing the dents and dings that can otherwise mar a case during sizing. Headspace is held to minimum tolerances throughout the process so case body length stays consistent from one loading to the next. This hardened steel die is cut to the exact .22 GT chamber dimensions matching the .224 bullet diameter the cartridge is loaded with. The second die in the set is a Seater Die fitted with a Bullet Seater Plug and a built-in roll crimper letting the handloader seat the bullet to the correct depth and crimp the case mouth in the same operation. Both dies thread into a standard 7/8-14 press the industry standard that fits the overwhelming majority of reloading presses on the market. The set ships in RCBS s signature green die box and is made in the USA reflecting the brand s long-standing reputation for precision reloading tools. For handloaders working up loads for the .22 GT this two-die set delivers the consistency and repeatability that accurate ammunition depends on.
