The RCBS 17601 full length die set for 300 Remington Ultra Magnum gives handloaders the essential tools needed to resize and seat ammunition for this powerful magnum rifle cartridge. Whether you're loading for a long-range hunting rifle or a precision target build, this two-die set handles the core operations that transform fired cases into safe, consistent ammunition. Built to RCBS's exacting standards, it's designed for shooters who take reloading seriously and want reliable, repeatable results.
The full-length sizer die does the heavy lifting: it resizes fired cases to SAAMI minimum dimensions, removes the spent primer, and opens the neck to accept a fresh bullet. The die incorporates vents that protect your cases by preventing air pressure buildup and managing excess lubricant during the resizing stroke. Headspace is held to tight tolerances so the case body length stays consistent, which matters when you're chasing accuracy. The included seater die handles bullet seating and features a built-in roll crimper that applies a uniform, secure crimp at the same time the bullet is seated.
For 300 RUM handloaders, this set removes guesswork from two critical steps in the reloading sequence. It's the kind of no-nonsense tool that appeals to hunters and range shooters who understand that ammunition quality directly affects field or target performance. Pair it with your press, case prep station, and other reloading gear to build ammunition tailored to your rifle's chamber and your shooting goals.
