Frequently Asked Questions
What makes the Terminal Ascent bullet different from other bonded hunting bullets?
Federal's Terminal Ascent combines a bonded lead core with the exclusive Slipstream polymer tip, which is engineered to initiate reliable expansion at velocities up to 200 fps lower than comparable designs. This means the bullet performs consistently whether you're shooting at 50 yards or 500 yards. The AccuChannel grooves also reduce bearing surface contact, cutting drag and improving accuracy without sacrificing terminal energy on impact.
Is the 280 Ackley Improved a good choice for long-range big-game hunting?
Absolutely. The 280 AI is widely regarded as one of the most efficient long-range hunting cartridges available. It pushes heavy, high-BC bullets like this 155gr Terminal Ascent to velocities that deliver flat trajectories, minimal wind drift, and retained energy well beyond 500 yards. It's an excellent choice for deer, elk, pronghorn, and similar big-game animals at extended distances.
How should I store this ammunition when not in use?
Store Federal Premium Terminal Ascent ammunition in a cool, dry location away from direct sunlight, heat sources, and moisture. Keep rounds in the original box or a sealed ammo can to protect the primers and propellant from humidity. Properly stored centerfire ammunition can maintain reliable performance for many years.
