The Federal Premium Rifle Ammo .308 Win 178 gr ELDX delivers match-accurate long-range hunting performance through its Extremely Low Drag eXpanding (ELDX) design, giving shooters a very high ballistic coefficient that holds velocity and reduces wind drift at distance; with a listed muzzle velocity of 2610 fps and muzzle energy around 2692 ft-lbs, this 178-grain .308 Winchester load is built to reach out and retain terminal effectiveness on big game like deer, antelope, and elk. Youll notice the polymer tip resists deformation in magazines and starts expansion even at extended ranges, while the concentric copper jacket and robust shank promote controlled, dynamic expansion across a wide range of impact velocities, so shots from near to far deliver predictable penetration and wound channels. As part of Federals ELDX series, this round appeals to hunters who want match-grade external ballistics combined with hunting terminal performance; whether zeroing for long shots, dialing for wind, or making ethical field shots in mixed-range terrain, this ammo gives you consistent trajectories, solid downrange energy, and reliable feeding in bolt guns and modern rifles. Made in the United States, brass-colored cartridge presentation, ORM-D hazardous goods classification noted for shipping.
