6mm Benchrest Ackley Improved 272 NK Murdica

The 6MM Benchrest Ackley Improved (6BRAI) Murdica & Dave Specification Chamber Reamer is designed for precision shooters seeking the proven accuracy of the 6mm BR platform with the increased velocity and improved case efficiency of the Ackley Improved design. Featuring a .272" neck diameter and zero freebore configuration, this reamer is optimized for shooters who demand exceptional concentricity, consistent bullet alignment, and maximum precision from custom benchrest and competition rifles.

Developed from extensive real-world competition experience, the Murdica & Dave specification combines the inherent accuracy of the 6BR cartridge with a sharper shoulder geometry that increases powder capacity while maintaining excellent brass life and feeding characteristics. The zero freebore design is ideal for shooters tailoring seating depth to specific bullet profiles and chamber requirements.
