Rcbs 9229 Single Stage Shell Holder 25 Automatic Colt Pistol (Acp) #29
The RCBS #29 Single Stage Shell Holder is purpose-built for reloading .25 ACP (Automatic Colt Pistol) ammunition. If you're setting up a single-stage or turret press to load .25 ACP, this hardened steel shell holder ensures consistent case alignment with your dies—critical for safe, accurate handloads. It's a straightforward, reliable component that takes the guesswork out of case positioning during the reloading process.
Shell holders are often overlooked, but they're essential to proper reloading. This holder is engineered to capture a specific depth of the case head, maintaining SAAMI-standard headspacing for your .25 ACP rounds. That precision matters whether you're loading for a vintage pocket pistol or a modern reproduction—inconsistent case seating can lead to pressure variations and feeding issues downrange.
RCBS shell holders are made from hardened steel, designed to withstand the repeated pressures of the reloading cycle. The #29 is sized exclusively for .25 ACP, so there's no confusion about which holder goes with which cartridge. If you're building a dedicated .25 ACP reloading setup or expanding an existing press to handle this often-underestimated cartridge, this is the right tool for the job.

Frequently Asked Questions
Will this shell holder work with my single-stage press?
Yes. The RCBS #29 is designed for use with single-stage and turret presses. It fits into the press ram and holds the case in proper alignment with your dies.
Is this shell holder specific to .25 ACP?
Yes. The #29 is sized specifically for .25 ACP cartridges. Each shell holder number corresponds to a particular case head diameter and dimension, so you'll need the correct holder for safe, consistent reloading.
What does the 0.125 inch case head capture mean?
The holder grips approximately 0.125 inch of the case head (the base of the cartridge). This depth of engagement ensures the case is held securely and positioned at the correct distance from the die, maintaining SAAMI-standard headspacing for reliable, safe ammunition.
Can I use one shell holder for multiple calibers?
No. Shell holders are caliber-specific. The #29 is made only for .25 ACP. Using the wrong holder can result in improper case alignment and unsafe ammunition.
