Product Overview
Hornady Frontier 55gr FMJ-BT is built for high-volume range days. The Lake City brass and boat-tail bullet design deliver consistent performance through AR-15s and bolt rifles alike. At 3,240 fps, the round cycles reliably in semi-auto platforms and feeds smoothly from standard magazines. Shooters who burn through hundreds of rounds per session will appreciate the combination of Hornady quality control and military-spec brass at a price point below Hornady's premium lines.
The 55gr FMJ-BT profile with a 0.243 G1 ballistic coefficient holds a reasonably flat trajectory out to 200 yards. That makes it a solid choice for informal steel matches, carbine courses, and zeroing optics. The boat-tail design gives it a slight edge over flat-base FMJ options at distance, where the reduced drag helps maintain velocity. Expect 2-3 MOA groups from a standard AR, which is more than adequate for training and practice drills.
New shooters breaking in an AR-15 will find Frontier a dependable starting point. The brass case is reloadable for those who want to save even more per round down the road. It also works well in bolt-action .223 rifles for cheap plinking. The FMJ-BT bullet won't expand on impact, so this load is strictly for paper, steel, and range use rather than hunting or defense.
- Lake City brass is durable and reloadable for handloaders
- Boat-tail design improves ballistic performance over flat-base alternatives
- Reliable feeding and cycling in AR-15 and Mini-14 platforms
- Lower cost per round than Hornady's premium ammunition lines
- Quality control can be inconsistent across different production lots
- Not suitable for hunting or defensive applications due to FMJ construction
- Some rifles show tighter groups with Federal AE or Winchester USA at the same weight
