RCBS Full Length Die Set for .350 Remington Magnum
The RCBS Full Length Die Set for .350 Remington Magnum gives you the core tooling needed to reload bottleneck cases for this hard-hitting cartridge. This two-die set includes everything essential: a full-length sizer die paired with an expander-decapping unit, plus a seater die with integrated bullet seater plug and roll crimper. Whether you're handloading for a classic magnum rifle or building match-grade ammunition for hunting, this set gets you started with the precision RCBS is known for.
The full-length sizer die brings your fired cases back to SAAMI minimum dimensions, ensuring consistent headspace and reliable feeding. It sizes the case body, removes the spent primer, and opens the neck in one stroke. Importantly, the die features built-in venting to prevent the case damage that occurs when air gets trapped during sizing—a detail that separates quality dies from budget alternatives and keeps your brass lasting through multiple reloading cycles.
The seater die does double duty: it seats your bullet to precise depth and applies a roll crimp in the same operation, locking the bullet securely in place without the hassle of a separate crimping step. That integrated crimper is a time-saver when you're loading volume, and it's especially useful if you're working with magnum rifle rounds where bullet retention matters.
