Easton 5mm FMJ Arrows

Easton 5mm FMJ arrows use a carbon fiber core wrapped in a thin aluminum jacket — a construction that combines the low flex of carbon with the mass and weight-forward balance of aluminum. The result is an arrow that flies flatter, hits harder, and penetrates deeper than a standard all-carbon shaft of the same diameter, particularly on heavy animals where pass-through performance matters.

Why Mass Matters for Big Game

Arrow kinetic energy and momentum are both functions of mass. Heavier arrows carry more momentum into the target, which translates directly to penetration depth on deer, elk, and black bear. FMJ arrows let you build arrow weight without going to extreme front-of-center setups that complicate tuning. The 5mm diameter — smaller than standard 6mm shafts — also reduces drag and wind drift at longer distances.

• Carbon core, aluminum jacket — maximum penetration per diameter
• 5mm diameter — reduced wind drift compared to 6mm shafts
• High weight-forward balance — enhanced penetration on heavy animals
• Consistent straightness and spine tolerance for accurate flight
• Compatible with standard 5mm inserts and points

Who Should Shoot FMJ

Elk, black bear, and large deer hunters shooting at 40 yards and under where pass-through performance is the primary goal. Also effective for competition 3D archery where the heavier shaft absorbs wind variation better than ultralight carbon. FMJ arrows are a step up from standard carbon in situations where penetration and consistency matter more than maximum speed.
