Hornady Custom 223 Remington 55 grain FMJ BT ammunition delivers consistent, factory-loaded accuracy for shooters who demand dependable performance at the range or in the field. Built on Hornady's reputation for quality control and precision manufacturing, these rounds pair a full metal jacket boat tail bullet with carefully selected components to produce the kind of shot-to-shot consistency that separates good ammo from great ammo. Whether you're zeroing a new rifle, running drills, or training for personal defense, this 223 load gives you the repeatability you need without the time investment of hand-loading.
Each round is hand-inspected before packaging as part of Hornady's commitment to quality—a standard that sets Custom ammunition apart from mass-produced alternatives. The FMJ boat tail design provides ballistic efficiency and reliable feeding, while the boat tail profile reduces drag for flatter trajectories and more predictable wind drift at distance. This combination makes it well-suited for target work, varmint shooting on small game under 50 pounds, and general practice where accuracy and consistency matter.
Hornady Custom ammunition represents the middle ground for serious shooters: factory convenience with handload-grade attention to detail. You get the speed and reliability of factory ammunition without the compromise on precision. The 223 Remington remains one of the most versatile rifle cartridges in America, and this 55-grain load is a proven platform for both semi-auto and bolt-action rifles. Box of 50 rounds.
