The RCBS 12701 full-length 2-die set for .264 Win Mag gives you the core reloading tools you need to produce consistent, safe ammunition for your magnum rifle. This is a purpose-built setup for handloaders working with bottleneck cartridges, combining a full-length sizer die with a seater die in one kit—eliminating guesswork about compatibility and reducing the hassle of sourcing dies separately.
The full-length sizer die does the heavy lifting: it brings your fired cases back to SAAMI minimum dimensions, sizes the case body, decaps the spent primer, and expands the neck to accept your bullet. RCBS engineered vents into the die to prevent case damage from trapped air and excess lubricant—a detail that protects your brass and your results. Headspace is held to minimum tolerances, so the die won't change case body length during sizing, which matters for precision and repeatability.
The seater die includes a built-in roll crimper, so you seat and crimp the bullet in one stroke. That simplifies your reloading sequence and helps you maintain consistent neck tension across your batch. Both dies feature the standard 7/8-inch-14 thread, so they'll fit any standard reloading press you already own.

Yes, provided your press accepts standard 7/8-inch-14 threaded dies. The RCBS 12701 uses industry-standard threads and will fit any conventional single-stage or progressive press designed for that thread size.
Full-length sizing, which this die performs, resizes the entire case body back to SAAMI minimum dimensions and decaps the primer—the complete reset you need for ammunition that will chamber reliably in any rifle. That's why full-length dies are the standard choice for most handloaders and are especially important when you're loading for a firearm you don't own or when consistency across a batch matters.
This set includes the dies for sizing and seating. You'll also need a reloading press, a powder scale, calipers, primers, powder, bullets, and brass cases—but the two dice handle the core resizing and bullet-seating work.
Yes. Full-length sizing brings your cases to SAAMI minimum spec, which ensures they'll chamber safely in any properly headspaced .264 Win Mag rifle.
