Hornady Frontier 5.56 NATO 55 grain FMJ ammunition hits that sweet spot between reliability and value. This is the classic M193 load that's been the training standard for the AR-15 platform for decades, and for good reason. With a muzzle velocity of 3240 fps and a ballistic coefficient of .243 (G1), these rounds deliver predictable performance across a wide range of shooting activities.
Frontier Cartridge is the result of Hornady partnering with the Lake City ammunition plant, bringing together quality bullet design with proven military-grade production. You get Hornady's reputation for consistency loaded into brass cases with military-grade boxer primers and propellant. The brass cases are also fully reloadable, which means serious range shooters can reload and shoot again for even less down the line. The key thing to know about reloading: military crimped primers require you to remove the crimp before reloading, but it's a straightforward process.
These rounds cycle reliably through AR-15s and other 5.56 NATO platforms, whether you're putting rounds downrange for training drills or zeroing in at the range. The 55 grain projectile is lightweight enough to keep recoil manageable, letting you focus on fundamentals and rack up accurate shots without the budget-busting cost of match ammunition. Multiple reviewers report consistent performance through hundreds of rounds with minimal issues.
Frontier ammunition covers everything from plinking and target shooting to hunting applications. If you're running drills on your rifle or just spending a day at the range, this load delivers the accuracy and reliability you need without requiring you to choose between shooting more and spending less.
Yes, the brass cases are fully reloadable. The military-grade boxer primers do have a crimp that needs to be removed before you can seat a new primer, which is a straightforward process. Once you remove the crimp, you can reload these cases just like standard ammunition brass, making them a great value for shooters who handload.
Absolutely. The 55 grain FMJ (M193) is the classic training and general-purpose load for the AR-15. It cycles reliably, produces manageable recoil, and delivers solid accuracy for range work and training drills. It's been the standard for decades for a reason.
Frontier combines Hornady's quality bullet design with Lake City's military-grade production standards, which gives it a solid reputation for reliability. Reviewers consistently report good cycling and accuracy through modern AR-15s and other 5.56 platforms, often without the reliability issues that plague some cheaper alternatives.
5.56 NATO is loaded to a slightly higher pressure than .223 Remington. You can safely fire 5.56 NATO in a 5.56 NATO chamber or a .223 Wylde chamber, but you should not fire factory 5.56 NATO in a .223 Remington chamber due to the pressure difference. Always verify your rifle's chamber marking before loading.
