The Hornady Custom Grade New Dimension Series IV Rifle 2-Die Set for .338/.378 Wby is a precision reloading die set engineered for handloaders working with this specialized wildcat cartridge. This two-die configuration pairs a full-length sizer die with a seater die, giving you the core tools needed to resize fired brass and seat bullets with repeatable accuracy. If you're building ammunition for a .338/.378 Weatherby or similar magnum rifle, these dies are built to the exacting standards Hornady applies across its Custom Grade line.
Each die features Hornady's proprietary design elements: the Zip-Spindle system locks in with zero play for perfectly aligned case loading, while the sliding alignment sleeve ensures your bullet seats vertically true to the case neck every time. The polished elliptical expander reduces friction and minimizes case-neck stretching during the expand-and-prime phase. A built-in crimper lets you taper-crimp without purchasing a separate die, and the all-steel seater adjustment screw with compression washer gives you fine control over bullet seating depth. All dies are hand-inspected, heat-treated, and hand-polished to a mirror finish—strong enough to last through thousands of rounds without marring your brass.
These dies come in a storage box and include Sure-Loc rings for easy fine-tuning. The sturdy steel decapper removes spent primers reliably, and a retainer ring simplifies cleaning and maintenance. Whether you're loading for a long-range hunting rifle or a specialized magnum build, this set combines proven Hornady engineering with the durability you need for consistent, accurate handloads.
