RCBS
The RCBS Full Length Die Set for 300 PRC is built for reloaders who demand precision and reliability when working up loads for this modern long-range bottleneck cartridge. This two-die set gives you everything needed to resize, deprime, and seat bullets in 300 PRC cases, all machined from RCBS's proprietary die steel and finished to their exacting tolerances. Whether you're fine-tuning ammunition for a long-range hunting rifle or match rifle, this set handles the core operations that define consistent, safe reloads.
The full-length sizing die is the workhorse of the set. It brings your 300 PRC cases back to SAAMI minimum cartridge dimensions, sizing the case body, decapping the spent primer pocket, and expanding the neck to accept your bullet. The die includes an expander-decapping unit and features vents designed to prevent case damage from trapped air and excess lubricant—a detail that protects your brass and extends its reloading life. Headspace is held to minimum tolerances, so the die won't stretch or shorten your case body during sizing, a critical factor for consistent chambering and accuracy.
The included seating die handles bullet insertion and crimping in a single stroke. It uses a built-in roll crimper to secure the bullet as you seat it, ensuring a consistent grip that resists setback and helps maintain pressure consistency shot to shot. Both dies use the standard 7/8×14 thread, so they'll fit any compatible single-stage or turret press in your setup.
RCBS backs this set with their reputation for quality control and customer support. The dies ship in RCBS's green die box, ready to integrate into your reloading bench. If you're new to 300 PRC reloading or upgrading from generic dies, this set gives you the precision tooling that serious long-range shooters rely on.

Yes. The full-length sizing die is designed to resize 300 PRC cases to SAAMI minimum dimensions, so it handles new, once-fired, and multiple-fired brass as long as the cases are sound and within normal wear limits.
