RCBS 32907 AR Series Small Base Die Set 6.5 Creedmoor Reloading

The RCBS 32907 AR Series Small Base Die Set delivers precision reloading for 6.5 Creedmoor ammunition in semi-automatic platforms. This specialized die set addresses the unique sizing requirements of AR-style rifles, ensuring reliable feeding and extraction in gas-operated systems.

What Makes This Different

Small base dies size cases to tighter tolerances than standard full-length dies, creating ammunition that chambers smoothly in semi-automatic rifles with minimal headspace variations. The AR Series design accounts for the dimensional requirements of gas-operated systems where case extraction occurs under pressure. Standard dies often leave cases slightly oversized for reliable function in autoloading rifles, making this specialized tooling essential for consistent performance.

Key Features

• Small base full-length sizing die reduces case diameter by additional 0.001-0.002 inches
• Precision-ground steel construction with heat-treated surfaces for extended service life
• Includes seating die with built-in roll crimp for secure bullet retention
• Compatible with standard 7/8-14 threaded reloading presses
• Shell holder #43 included for proper case positioning during sizing operations
• Detailed instructions with load data references and setup procedures
• Engineered specifically for 6.5 Creedmoor cartridge dimensions and tolerances

This die set excels in competitive shooting environments where ammunition consistency directly impacts accuracy potential. The small base sizing ensures reliable function in match rifles, hunting semi-automatics, and tactical platforms chambered in 6.5 Creedmoor. Cases sized with this die set demonstrate improved extraction reliability under rapid-fire conditions and maintain consistent chamber fit across multiple firearms.
