Preston Moore conducted a comprehensive test of PMC X-Tac M855 62gr ammunition across eight different chrome-lined AR-15 barrels. The test focused on 30-shot groups at 100 yards, measuring both velocity and accuracy using advanced tools like the Garmin Xero C1 Pro and Ballistic-X app. Moore's 'A-ZED' metric provided practical accuracy insights, revealing that LMT, Krieger, and Noveske barrels generally performed best with this specific ammunition load, while Daniel Defense and Red Right Hand barrels showed less favorable results.

This video features a head-to-head comparison of two BCM BFH ELW (Enhanced Lightweight) AR-15 barrels. The creator conducts thorough inspections, including borescoping and headspace checks, revealing some unexpected findings. The testing involves shooting 30-shot groups at 100 yards with three different ammunition types: Winchester 55gr M193 FMJ, Frontier 68gr BTHP, and Federal Gold Medal 77gr SMK. Data is collected using a Garmin Zero C1 Pro chronograph and a Mantis X10 Elite, with results analyzed using mean radius and a custom A-ZED scoring system. The video aims to determine the consistency and real-world accuracy of these specific barrel models and whether any bore anomalies correlate with performance.
