RCBS 7mm STW Full Length Reloading Dies Set

The RCBS 7mm STW full length reloading dies set gives you the core tooling you need to reload bottleneck rifle cases with confidence. Whether you're preparing ammo for a long-range hunt or putting rounds downrange at the bench, a quality full length die set is the foundation of repeatable, safe handloading. This two-die configuration handles the heavy lifting of case prep and bullet seating, letting you focus on load development and consistency.

Full length sizing prepares your fired cases for reliable chambering in your rifle. The sizing die bumps the shoulder and bodies down the case, then decaps the spent primer—all in one stroke. The integrated expander ball sizes the case neck to proper bullet tension. Since full length sizing works on the entire case, it's the go-to method when you're loading for multiple rifles or when cases have seen several firings and need a fresh start. Just remember to lube your cases before running them through the sizing die.

The seating die completes the pair, seating bullets precisely and consistently. It includes a built-in crimp ring, so you can crimp or skip it depending on your load—simply adjust die height in your press to engage or disable the crimp. This versatility means you can tailor your setup to your rifle and ammunition needs without swapping dies. RCBS dies are built to last; many reloaders wear out multiple barrels using the same die set.

If you're new to handloading, a full length die set like this is exactly where you should start. Learn to set it up correctly, dial in your shoulder bump and seating depth, and you'll have the skills to reload safely and accurately for years to come.
