Built by RCBS for handloaders who demand consistent case alignment, the RCBS Shell Holder #29, 25 Automatic Colt Pistol (ACP) is a hardened-steel shell holder purpose-fit to its designated case-head diameter. RCBS catalogs this as shell holder #29 (part no. 9229), sized specifically for the 25 Automatic Colt Pistol (ACP) case head. Machined from hardened steel, it locks the cartridge case square to the ram so the sizing, expanding, and seating dies all meet the case on the same axis, stroke after stroke. It is a simple, small part, but a mismatched or worn shell holder is one of the most common causes of crooked cases and inconsistent headspace at the reloading bench.

Key Specifications

• Precision shell holder engineered by RCBS specifically for single-stage and turret press reloading setups.
• Hardened steel construction resists the repeated ram pressure of full-length sizing and seating without deforming.
• Precision case-head fit positions the cartridge case correctly against the shell-holder shoulder for proper SAAMI headspacing.
• Sized for 25 Automatic Colt Pistol (ACP) so the case seats squarely every time without wobble in the shell-holder pocket.
• Compatible with single-stage and turret presses the same shell holder body works across both press styles.
• Sold individually one shell holder per package, ready to drop straight into the press ram.
• Ships at 0.0375 lb light enough that a full set of shell holders takes up almost no room in a die cabinet.
• Snap-in shell-holder base seats into RCBS, and most other, standard press ram slots without tools.
• Shell holder #29 designation cross-references directly to RCBS’s shell-holder numbering system for quick reordering.
