Rcbs Full Length Die Set Group D Bottleneck Rifle Cartridge .308 Norma Mag

The RCBS Full Length Die Set for .308 Norma Magnum is a two-die reloading system built for shooters working up loads for this powerful bottleneck magnum cartridge. Whether you're assembling match ammunition for long-range competition or preparing hunting rounds for big game, this set handles the core tasks of case sizing and bullet seating with the precision RCBS dies are known for. If you're hand-loading for .308 Norma Mag, you need dies that understand the demanding geometry of a magnum case—this set is purpose-built for that job.

The Full-Length Sizer Die is the foundation of the set. It sizes the case body down to SAAMI minimum dimensions, which keeps your cartridge consistent and ensures reliable chamber fit shot to shot. During sizing, the die simultaneously de-primes spent primers and expands the neck to prepare it for a fresh bullet. The die includes internal venting to prevent trapped air and excess lubricant from damaging cases—a practical detail that extends case life when you're investing time in premium magnum brass.

The Seater Die completes the operation with integrated bullet seating and roll crimping in one step. This means you seat the bullet and secure it with a crimp in a single stroke, speeding up your loading sequence without sacrificing consistency. The built-in design eliminates the need for a separate crimping step, making the process more efficient while maintaining the secure bullet hold that magnum velocities demand.
