RCBS 9221 Shell Holder #21 for 303 Savage Single Stage Press

The RCBS 9221 Shell Holder #21 delivers precise case positioning for 303 Savage cartridges in single stage reloading presses. This hardened steel shell holder maintains consistent alignment during the resizing, priming, and bullet seating operations that define quality handloading.

What Makes This Different

RCBS shell holders feature case-hardened construction that resists wear from repeated cycling through thousands of reloading operations. The #21 designation specifically matches the rim diameter and case head dimensions of 303 Savage cartridges, eliminating the loose fit or binding issues common with generic holders. Internal dimensions hold tolerances within 0.001 inches for reliable case extraction and feeding.

Key Features

• Case-hardened steel construction withstands 10,000+ reloading cycles
• Precision-machined internal dimensions for 303 Savage case heads
• Universal fit with all RCBS single stage and turret presses
• Compatible with most other single stage press brands
• Spring-loaded ejection system prevents stuck cases
• Corrosion-resistant finish maintains smooth operation

Reloaders processing 303 Savage ammunition for vintage rifles like the Savage Model 99 require the exact case support this shell holder provides. The hardened steel construction handles the substantial forces generated during full-length resizing of these bottleneck cases. Match-grade ammunition production depends on the consistent case positioning this holder delivers throughout the reloading sequence.
