Long known for its ability to penetrate light steel armor, the XM855 is one of the premier rounds used in the US Armed Forces. The Federal 62gr 5.56x45 Full Metal Jacket now brings that same level of performance and quality to your doorstep, and is one of the preeminent home self-defense rounds in production today.

The 62gr steel tipped core penetrator is capable of penetrating through mild steel targets within 100 yards. Due to the inherent hardness and velocity of the round, intermediary barriers such as glass, cylinder blocks, and drywall can be penetrated with little to no deviation of the bullets flight path. This is of particular importance to law enforcement offficers who often have to engage threats in a dynamic urban environment. At a muzzle velocity upwards of 3,025 feet per second, supersonic flight can be sustained well out to 500 yards, and is one of the core reasons the the Federal 62gr 5.56x45 FMJ one of the most lethal and effective rounds for self defense.

Patriots looking to protect themselves with a round engineered for optimum performance will find a true ally in the Federal 62gr 5.56x45 FMJ.

A: Hi Trey! The Colt M4A1 SOCOM Carbine comes with a factory barrel twist of 1:7. You would find that a faster barrel twist of 1:8 or 1:9 would give you the best accuracy with a 62 grain bullet. But this is not to say your rifle won't do just fine with this ammo. tt should still offer acceptable accuracy, especially if you're just doing some regular target practice and not long-distance sniping.
