Lee Precision 90981 Pacesetter 3-Die Set 223 Ackley Improved

The Lee Precision 90981 Pacesetter 3-Die Set transforms standard .223 Remington cases into high-performance .223 Ackley Improved cartridges. This complete die set delivers the precision tooling needed to create the improved cartridge known for increased velocity and enhanced case life. Reloaders gain access to the ballistic advantages of the Ackley Improved design with Lee's proven manufacturing quality.

What Makes This Different

The .223 Ackley Improved offers approximately 100-150 fps velocity increase over standard .223 Remington with identical bullet weights. The 40-degree shoulder angle and minimal body taper create superior powder capacity while maintaining safe chamber pressures. This die set includes the specialized tooling required for the fireforming process and subsequent reloading operations that standard .223 dies cannot accomplish.

Key Features

• Complete 3-die set for .223 Ackley Improved cartridge formation and reloading
• Full-length sizing die with expander ball for consistent case preparation
• Bullet seating die with built-in roll crimp for secure bullet retention
• Factory crimp die for uniform case mouth treatment and improved accuracy
• Hardened steel construction with precision-machined chambers
• Standard 7/8"-14 threads fit most single-stage and turret presses

The Pacesetter series provides reliable performance for both fireforming virgin brass and reloading established cases. Competition shooters benefit from the improved ballistic coefficient and reduced wind drift at extended ranges. The enhanced case capacity supports heavier bullet weights while maintaining acceptable pressures for bolt-action rifles. Hunters appreciate the flatter trajectory and increased downrange energy retention.
