RCBS Full Length Die Set - Group G - Bottleneck Cartridges 9.3mmx64 Brenneke

The RCBS Full Length Die Set – Group G for 9.3mm x 64 Brenneke bottleneck cartridges delivers precision case preparation essential for reloaders seeking consistent, safe ammunition. This two-die reloading set includes a full-length sizer die with expander-decapping unit and a seater die with bullet seater plug, providing the core tools needed to resize, deprime, and seat bullets to SAAMI minimum specifications. The full-length sizing process brings cartridge dimensions to standardized tolerances, critical for bottleneck cases where headspace control directly affects both accuracy and safety.

The sizer die features integrated vents that prevent case damage from trapped air and excessive lubricant accumulation—a design detail that extends case life and reduces reloading defects. The die sizes the case exterior, removes spent primers via the decapping pin, and expands the neck uniformly to accept the bullet. The seater die then positions and seats the bullet to precise depth, ensuring consistent cartridge length across batches. For 9.3mm x 64 Brenneke reloading, which serves hunting applications requiring reliable performance, this level of dimensional control translates directly to consistent velocity and accuracy across multiple firing cycles.

This die set is engineered for handloaders reloading European bottleneck cartridges, particularly those working with 9.3mm Brenneke cases for rifle applications. RCBS Group G dies are designed for specific cartridge families, ensuring proper fit and function with standard reloading presses. Whether processing once-fired brass or new cases, the full-length sizing approach accommodates dimensional variation while maintaining headspace within minimum tolerances—essential for consistent powder charge burning and bullet performance.
