The RCBS 30801 full length die set for 300 Winchester Short Magnum gives you the core tools needed to reload 300 WSM ammunition safely and consistently. This two-die set includes a full length sizing die and a seater die—the foundational pair that handles the heavy lifting in any reloading operation. Whether you're prepping fresh brass for a new hunting rifle or keeping a proven magnum fed through multiple barrel lives, a quality full length die set is where serious reloaders start.

The full length sizing die does the real work: it bumps the case shoulder to your desired specification (adjusted via die position), sizes the case body so it chambers without resistance, and decaps the spent primer in one stroke. The expander ball inside sizes the neck to the correct bullet tension. You'll need to lube your cases before running them through, but that's standard practice. Once sized, the seater die positions your bullet at the correct depth and includes a crimp ring so you can add a light crimp to the case mouth if you want it—just adjust the die up or down in the press to engage or bypass the crimp.

RCBS die sets are built to last. Many shooters get through multiple barrel replacements on a single set. If you're new to reloading, start here: learn to set up and use a full length die set properly before branching into neck sizing or other specialized dies. Consistency in your setup—shoulder bump, case length, primer seating, and bullet seating depth—is what separates loads that shoot from loads that shoot well.

Frequently Asked Questions

What's included in this die set?

The RCBS 30801 includes two dies: a full length sizing die (with decapping pin and expander ball) and a seater die with a crimp ring. These are the two essential tools for reloading 300 WSM bottleneck cases.

Do I need to lubricate my brass before using the sizing die?

Yes. Cases must be lubricated before full length sizing to prevent sticking and ensure smooth operation through the sizing die.

Can I adjust the shoulder bump on my 300 WSM cases?

Yes. The shoulder bump is controlled by adjusting the full length sizing die up or down in your press. Many reloaders use a cartridge headspace gage tool to dial in the correct shoulder bump for their specific rifle.

Can I crimp the case mouth to the bullet?

Yes. The seater die includes a built-in crimp ring. Raise or lower the die position in the press to engage the crimp or bypass it entirely, depending on your load requirements.
