The RCBS 25 WSSM full length reloading dies set is built for handloaders working with .25 WSSM bottleneck cartridges who need precision and consistency. This two-die set handles the complete process—from resizing fired cases to final bullet seating—using RCBS's time-tested design and manufacturing. Whether you're fine-tuning loads for a varmint rifle or refining accuracy for the range, this die set gives you the control to produce ammunition matched to your rifle's tolerances.

The full-length sizer die is the workhorse of the set. It brings fired cases back to SAAMI minimum dimensions, sizes the case body, removes the spent primer, and expands the neck to accept a fresh bullet. Vents in the die housing prevent case damage from trapped air and keep excess lubricant from building up inside the cartridge—a detail that matters when you're processing volume or pushing tight tolerances. Headspace is locked to minimum specs to preserve case dimensions and avoid unwanted shifts during sizing.

The seater die completes the operation with a built-in roll crimper that seats the bullet and applies a secure crimp in one stroke. This integrated crimping design saves setup time and delivers uniform bullet seating, which translates directly to tighter groups on paper. Both dies use the standard 7/8-inch-14 thread, so they'll fit any compatible reloading press in your shop.
