From 3D tournaments to taking large game, Easton???s 5mm FMJ Match Grade and hunting arrows are an excellent choice. They feature a micro diameter, this low profile delivers greater accuracy and performs well in crosswinds. The FMJ???s slick surface also makes it easy to pull from targets and promotes greater broadhead penetration. Like all of the arrows in Easton???s FMJ series, the 5mm FMJ features a technologically advanced arrow shaft designed for penetration, accuracy, and clean kills. The FMJ starts as a carbon foundation using the Accucarbon process of fusing high-strength carbon fiber with aerospace grade resin for a more consistent spine and weight. This carbon fiber core is then permanently bonded inside of an aluminum tube, and the synergy between the two creates greater ballistics efficiency, more impact energy, and more momentum. The result is an arrow that???s highly effective on larger game.
