The RCBS 9212 Single Stage Shell Holder #12 is a precision reloading component built to handle 17/22 Hornet and 22 K-Hornet cartridges. If you're hand-loading ammunition for these vintage or specialized rimfire-based rounds, this shell holder is the foundation of consistent, safe reloads—it positions your case dead-center in your press and locks it solid during all the resizing, priming, and bullet-seating steps. Whether you're working on a single-stage or turret press, this holder ensures your cases align properly with your dies, eliminating the variables that lead to sloppy rounds or damaged brass.
Built from hardened steel, the RCBS 9212 is engineered to last through hundreds of reloading sessions. The design captures 0.125 inch of the case head, holding your cartridge at the correct SAAMI headspace reference point so you can size and reform cases with confidence. This isn't a generic holder—it's sized specifically for the small case head dimensions of the Hornets, so don't try to force a different caliber into it.
If you're running a hand-loading setup for these niche cartridges, you already know that finding the right components means the difference between frustrating hunting trips and tight, reliable ammunition. The RCBS 9212 does one job and does it well: it keeps your case centered and your reloads consistent, session after session.
