RCBS 9225 Single Stage Shell Holder #25 for 8mm Nambu Reloading

The RCBS 9225 Single Stage Shell Holder #25 secures 8mm Nambu cartridge cases during the reloading process with precision-machined tolerances. This shell holder eliminates case movement and provides consistent cartridge positioning for accurate powder charges and bullet seating.

What Makes This Different

The #25 shell holder features hardened steel construction with exact dimensional specifications for 8mm Nambu cartridges. Unlike universal shell holders that compromise fit, this dedicated holder maintains case concentricity within 0.002 inches. The precision-ground interior surfaces prevent case damage while ensuring reliable extraction after resizing operations.

Key Features

• Hardened steel construction resists wear from repeated cycling
• Precision-machined interior fits 8mm Nambu case rim dimensions exactly
• Compatible with all RCBS single stage presses and most competitor models
• Numbered identification (#25) prevents confusion in multi-caliber setups
• Chamfered entry aids smooth case insertion and removal
• Heat-treated steel maintains dimensional stability under pressure
• Standard 7/8-14 thread pitch fits industry-standard presses

Reloaders working with 8mm Nambu cartridges require consistent case support throughout the reloading cycle. This shell holder maintains proper case alignment during full-length resizing, neck sizing, and bullet seating operations. The precise fit prevents case rim deformation that can cause feeding issues in semi-automatic pistols. Competition shooters benefit from the repeatable cartridge positioning that contributes to consistent velocities and accuracy.
