The Hornady Custom Grade Series I 2-Die Set for 300 RUM gives you the precision tooling needed to reload this powerful magnum cartridge with confidence. Built for shooters working with less common calibers, this two-die set pairs a full-length sizing die with a bullet seater die—the core components for consistent, safe ammunition. Hornady backs these dies with a lifetime guarantee against breakage or wear from normal use, so you're investing in reloading equipment that will outlast years of rounds downrange.
The 300 RUM demands attention to detail, and this set delivers the adjustment precision to meet that demand. The Zip Spindle design on the sizing die locks positively to eliminate any creep or slippage during the critical sizing stroke. Fine-threaded spindle and collet allow you to dial in incremental adjustments for tight tolerances, or zip up and down for larger movements when you're fine-tuning your setup. The smooth-finish lock rings include wrench flats for secure, repeatable positioning die-to-die.
The seater die features an in-line bullet seating system with a built-in crimper, keeping your setup compact and your process streamlined. An elliptical expander ensures consistent case mouth preparation, while the seater adjustment screw retainer ring keeps everything indexed where you set it. Hornady's reputation for internal finish quality means less drag, smoother function, and greater longevity across thousands of reloading cycles.

Frequently Asked Questions
What dies are included in this set?
The set includes a full-length sizing die and a bullet seater die. These are the two essential dies for 300 RUM reloading: the sizing die prepares your fired brass, and the seater die loads and seats bullets into the prepared cases.
Is this set suitable for reloading 300 RUM?
Yes. This Hornady Custom Grade set is designed for the 300 RUM, one of the larger magnum rifle cartridges. If you're reloading 300 RUM ammunition, this set gives you the tooling you need.
Does the seater die have a built-in crimper?
Yes. The seater die includes a built-in crimper, allowing you to seat and crimp in one die stroke for streamlined reloading.
What makes the Zip Spindle design different?
The Zip Spindle positively locks to the die body to eliminate slippage. Fine-cut threads on the spindle and spindle collet let you make small, precise adjustments by turning the spindle, or quickly zip the die up or down for larger position changes. This keeps your sizing consistent and repeatable.
