Hornady’s 5.56mm 55 grain GMX TAP Barrier ammunition (#81255) uses the same 55 grain GMX projectile that is available as a reloading component. The 55 grain GMX bullet is a monolithic hollow-point, but unlike similar monolithic bullets such as the all-copper Barnes TSX, the Hornady GMX is made from gilding metal (95% copper and 5% zinc). Hence the “GM” portion of GMX.
Hornady SuperPerformance 165 GMX which were 3/4" at 100, but then 5" at 200; and, Hornady SuperPerformance 150 GMX of which I only fired 2 rounds because they showed very clear signs of excessive pressure - very stiff bolt lift, smeared bases, primer cratering, and stretched brass. Bottom line, the Federal 165 & 180 Barnes.
