Hornady Frontier Lake City 5.56mm NATO ammunition (brand part no. FR240) pairs a genuine Hornady hollow point bullet with components built to Lake City specifications, giving shooters a match-grade round with real terminal performance. Hornady loads this round with a 55 grain hollow point on a brass case, a bullet designed to expand rather than simply punch through like a standard FMJ. Frontier Cartridge ammunition covers a wide range of applications, from plinking and target shooting to law enforcement training and self-defense, and this hollow point loading is well suited to the latter uses where terminal performance matters. The 20-round box is a practical size for a focused range or duty-verification session.
