Aguila Centerfire Rifle Brass 5.56 55 Grain 300-Rounds Bulk FMJBT

Overview

Aguila 5.56x45mm NATO Features The Aguila 55 gr 5.56x45mm NATO FMJBT load is built around a full metal jacket boat tail bullet that provides reliable feeding across AR-15 and other 5.56x45mm NATO semi-automatic and bolt-action platforms with the boat tail profile delivering reduced drag and improved retained velocity at distance compared to flat-base FMJ alternatives making it a more capable training round at the longer distances that precision and competition shooters push their rifles to. At 3260 fps and 1298 ft-lbs of muzzle energy this load delivers the full-velocity high-energy performance that the 5.56x45mm NATO cartridge is capable of from a standard AR-15 barrel length producing the flat trajectory and consistent wind performance that target and range shooters demand from a reliable training load. For competitive shooters running 3-Gun precision rifle or carbine matches who need a consistent high-velocity 5.56x45mm NATO load that delivers reliable performance at both short and extended range distances the Aguila FMJBT delivers the ballistic performance the application demands. The brass casing is fully reloadable providing additional long-term value for shooters who maintain an active reloading program and want to recover high-quality dimensionally consistent brass that will reload cleanly and reliably across multiple loading cycles. The 300-round bulk box format provides a meaningful training and range ammunition supply in a single purchase making it a practical choice for AR-15 owners who want to stock up for a training period or competition season without paying retail box premiums on smaller quantities. Aguila has been manufacturing ammunition in Mexico since 1961 and is one of the most widely distributed and respected ammunition manufacturers in the Western Hemisphere with quality control standards and manufacturing consistency that serious rifle shooters have relied on across decades of production. The boat tail construction makes the Aguila 55 gr FMJBT a more versatile training round than standard flat-base FMJ alternatives providing meaningful ballistic performance at extended range distances that flat-base training loads cannot match while still delivering the reliable feeding and consistent cycling that high-round-count range and competition use demands. The combination of brass casings boat tail bullet profile and 300-round bulk format makes this load one of the most complete value propositions available in 5.56x45mm NATO training ammunition for shooters who want both immediate range utility and long-term reloading value in a single purchase.
