The RCBS 308 Marlin Express full length die set gives handloaders the precision tooling needed to reload this popular lever-action cartridge with confidence. If you're working up loads for a Marlin 308, whether for hunting or target shooting, this two-die set handles the essential sizing and seating operations that form the foundation of consistent, safe ammunition.
The full-length sizer die does the heavy lifting: it brings fired cases back to SAAMI minimum dimensions, resizes the case body, removes the spent primer, and opens the neck to accept a fresh bullet. Built-in vents prevent case damage from trapped air or excess lubricant—a thoughtful design detail that protects your brass. The headspace is held to minimum tolerances so you're not unnecessarily changing case length during sizing, which helps your rounds chamber cleanly and perform predictably.
The seater die completes the process with an integral roll crimper, securing the bullet in place while you seat it to the correct depth. This one-step crimping saves time and ensures a uniform, reliable hold on your projectile. Both dies use standard 7/8-inch-14 threads, so they'll work with any compatible reloading press you already own.

Frequently Asked Questions
Will this die set work with my current reloading press?
Yes, provided your press accepts standard 7/8-inch-14 threaded dies. This is the industry-standard thread size for most single-stage and progressive presses.
What caliber is this die set designed for?
This set is purpose-built for the 308 Marlin Express, so it's sized and designed specifically for that cartridge's case and headspace dimensions.
Does the seater die crimp, or do I need a separate crimping step?
The seater die includes a built-in roll crimper, so you seat and crimp in one operation—no separate step required.
What's included in the set?
You get two dies: a full-length sizer die with an integrated expander-decapping unit, and a seater die with a bullet seater plug and roll crimper.
