The Federal Terminal Ascent .280 Ackley Improved load fits hunters who want match-grade long-range accuracy in a bonded hunting bullet. The 155-grain Terminal Ascent has a patented Slipstream polymer tip that starts expansion at velocities 200 fps lower than comparable designs, and Federal rates the muzzle velocity at 2930 fps. A copper shank and bonded lead core retain weight for deep penetration at close range, while the long, sleek profile keeps wind drift and drop low. It is a factory-loaded answer for a .280 Ackley Improved rifle on big game at any range.
