May 2015, Performance Test in LA, USA

First test

• Muzzle velocity is almost 900m/s in 5.56mm caliber / M4 14.5″ barrel / 50~300m shot range /
• Optimizing test for Air-guiding grooves angle of HPP
• Magnus force test including the angle of grooves variation
• Accuracy test for optimized HPP

Result

1. Set-up the optimized angle of grooves
2. Check the different between the conventional ballistics and HPP’s ballistics
