The Hornady 55 grain GMX .224" projectile is a monolithic gilding-metal hollow point. It does not have a polymer tip. It's significantly longer than a typical lead-core/jacketed FMJ bullet. The bullet is a blind to barriers projectile, though accuracy/precision is not on par with say, the Speer Gold Dot projectiles in this caliber. The relief band also serves as a cannelure.
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.

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.
