Federal Rifle Ammunition Features This Federal load pushes a 64 grain bonded soft point bullet chambered for 5.56x45mm rifles including AR-platform carbines. The bonded construction fuses the jacket to the lead core which keeps the bullet from separating during impact and promotes more reliable expansion than a standard unbonded soft point. Brass casing feeds and extracts reliably across most semi-automatic rifle platforms chambered in 5.56x45mm. This combination of bonded construction and a 64 grain weight gives the round a balance between penetration and expansion suited to hunting medium game as well as range use. Packaged 20 rounds per box this load is sized for range sessions and field carry alike without excess bulk. The soft point profile is designed to expand on impact while the bonded jacket resists fragmenting prematurely preserving weight retention through deeper penetration. Shooters running 5.56x45mm rifles for hunting or general-purpose use benefit from the bonded bullet s more predictable terminal performance compared to standard training ammunition. This Federal load gives 5.56x45mm shooters a dependable field-ready option from a well established domestic ammunition manufacturer.
