The RCBS 31301 full length die set for 270 Winchester Short Magnum delivers the core tools serious reloaders need to produce consistent, safe ammunition. A full length die set is the foundation of rifle reloading—it includes a full length sizing die and a seater die, giving you everything necessary to resize fired cases and seat fresh bullets for reliable feeding and accuracy.
The full length sizing die handles the heavy lifting: it bumps the shoulder of the case to your adjusted specifications, sizes the body so rounds chamber easily, and decaps the spent primer in one operation. An expander ball passes through the neck to size it to proper bullet tension. This approach works for both bottleneck rifle cases and allows you to control headspace by adjusting the die position in your press—though we recommend using a cartridge headspace gage tool to dial in the correct shoulder bump for your rifle. Cases must be lubricated before sizing to prevent damage.
The seater die seats bullets reliably whether you're loading full length sized or neck sized cases, and it includes a built-in crimp ring. Adjust the die up or down in your press to engage or skip the crimp feature depending on your ammunition design. Many shooters run through multiple barrels on a single die set, making this a durable investment in your reloading bench. If you're starting out, a full length die set is the right first step—learn to set these dies correctly, and you'll have the confidence and skill to explore other reloading techniques later.
The 270 WSM is a popular magnum cartridge among hunters and long-range shooters. This RCBS set gives you the precision tools to reload for it consistently, helping you maximize velocity, accuracy, and component efficiency in a caliber that demands careful attention to load development.
