RCBS Full Length Die Set - Group A - Popular Rifle Cartridge .338 RCM

The RCBS Full Length Die Set - Group A for the popular rifle cartridge .338 RCM is the precision reloading system trusted by competitive shooters, hunters, and military riflemen who demand repeatable accuracy and tight case dimensions. This three-die set provides the complete solution for full-length sizing, which is essential for semi-automatic rifles and firearms with tight chamber tolerances. Whether you're hand-loading match-grade ammunition for long-range precision work or preparing field loads for hunting applications, this die set delivers the consistency required to maximize performance from this intermediate magnum cartridge.

RCBS full-length dies feature superior construction and precision machining that resize the entire cartridge case—from the shoulder through the base—ensuring uniform chamber fit across multiple firings. The Group A configuration includes a full-length sizing die, a bullet-seating die, and a decapping/primer pocket cleaning die, providing a complete reloading cycle in one compact set. The hardened steel construction and carbide surfaces resist wear from repeated use, maintaining dimensional accuracy through thousands of reload cycles. The .338 RCM cartridge demands controlled case pressure and precise bullet seating geometry; RCBS dies are engineered to hold tolerances well within SAAMI specifications, critical for safe and consistent performance.

This die set is ideal for shooters handloading the .338 RCM in AR-10 platform rifles, bolt-action hunting rifles, and precision shooting platforms where full-length sizing is necessary to maintain reliable feeding and chamber fit. The compact 4.45 x 1.75 x 5.95-inch profile stores efficiently on a reloading bench and integrates seamlessly with standard single-stage or progressive reloading presses using standard 7/8-14 TPI threads. Serious reloaders—from military armorer backgrounds to competitive shooters—choose RCBS die sets for their consistency, durability, and the confidence they provide in ammunition quality and firearm reliability downrange.
