RCBS 9204 Single Stage Shell Holder #4 Multi-Caliber Steel (4 oz)

The RCBS 9204 Single Stage Shell Holder #4 is a hardened steel precision component engineered to center your cases during every reloading cycle. If you're running a single-stage or turret press and working with cartridges that use the #4 holder specification, this tool ensures your case sits at the exact height needed for proper die alignment—the foundation of consistent, safe reloads. Built tough to handle the mechanical demands of bench reloading, it captures 0.125 inch of the case head to achieve correct SAAMI headspacing, the specification your ammunition must meet.

Shell holders are one of those unglamorous pieces of reloading gear that make the difference between amateur and reliable ammunition. A worn or incorrect holder throws off your headspace, which ripples through every dimension downstream: powder charge compression, bullet seating depth, and ultimately, pressure curves and accuracy. The RCBS 9204 is your guarantee that case positioning stays consistent, reload after reload, so you can focus on the variables you're actually tuning.

This is the holder for multi-caliber reloading within the #4 class—check your press manual or reloading manuals to confirm your cartridge matches this size. Once you do, it becomes a workhorse accessory that will outlast many presses. Weighing 4 ounces, it's compact enough for any bench setup.

Frequently Asked Questions

What calibers does the RCBS #4 shell holder fit?

The #4 holder is designed for specific cartridges within that holder classification. Consult your reloading manuals or press documentation to confirm your cartridge matches the #4 specification—shell holder size is determined by case head diameter, not cartridge name.

Will this shell holder work on my single-stage press?

Yes. The RCBS 9204 is designed for both single-stage and turret press compatibility, fitting the standard shell holder slot on those machines.

What does the 0.125 inch case head capture mean?

The holder grips the case head to position it at the proper depth in your die. Capturing 0.125 inch of the case head ensures correct SAAMI headspacing—the standardized dimension that keeps pressure and performance predictable and safe.

Is this a replacement for a worn shell holder?

If your current #4 holder is damaged or worn, or if you're setting up a new press, the RCBS 9204 functions as a complete shell holder for any reloading station working with #4-class cartridges.
