RCBS
The RCBS 17801 full length die set for 7mm Remington Ultra Magnum is a two-die reloading setup designed for shooters who want to reload bottleneck rifle cartridges with precision and consistency. Whether you're working up loads for a long-range magnum rifle, preparing ammo for the range, or building ammunition for hunting, a quality full length die set is the foundation of repeatable, safe reloading. This set includes everything you need to resize cases and seat bullets—the two essential operations that form the core of the reloading process.
The full length sizing die bumps the case shoulder and sizes the body, allowing fired cases to chamber reliably in your rifle on the next firing. As the die works, it also decaps the spent primer, readying the case for a fresh one. An expander ball inside the die sizes the case neck to the correct tension for bullet seating. The included seater die positions bullets with accuracy and features a built-in crimp ring—you control whether to crimp or not by adjusting die height in your press. For shooters new to reloading, a full length die set like this is the logical starting point; it teaches you the fundamentals and will likely outlast multiple barrels on your rifle.
Note that cases must be lubricated before full length sizing to prevent sticking and ensure smooth operation. Many experienced reloaders recommend using a headspace gage tool to dial in the correct shoulder bump for your specific rifle and load. Once you master the basics with this set, you'll have the knowledge to explore other reloading techniques—but a quality full length die set remains a workhorse that belongs in every reloader's toolbox.
