Federal Premium Terminal Ascent .270 WSM ammunition combines two things that have historically been tough to merge into one round: the precision of a match-style bullet with the reliable, hard-hitting performance of a bonded hunting bullet. That balance is exactly what you need when hunting situations can vary wildly from a close-quarters encounter to extended-range opportunities.
What sets this round apart starts with the bullet itself. The lead core is chemically bonded directly to a solid copper shank that runs the length of the projectile. This bonded construction means the bullet won't separate under impact stress, whether that impact happens at close range or after a long-distance flight. You're getting deep, consistent penetration paired with excellent weight retention. That matters because premium hunting ammunition has to perform whether your quarry is 30 yards or 300 yards away.
Federal engineered the Slipstream tip to initiate expansion at velocities roughly 200 fps lower than comparable designs. Inside the polymer is a hollow cavity that, upon impact, allows fluid to enter and build pressure for controlled expansion even at reduced velocities. This design philosophy means you won't get blown-up bullets at close range or failed expansion at distance. The tip itself uses a small, flat meplat design that minimizes drag during flight without sacrificing the structural integrity needed for reliable performance.
AccuChannel grooves cut into the bullet shank serve a dual purpose. Traditional grooves improve accuracy and reduce barrel fouling, but they also increase drag and hurt ballistic coefficient. Federal's engineers discovered that with fewer grooves and a gentler slope rather than the typical 90-degree cut, they could retain the accuracy benefits without compromising long-range performance. Combined with the bullet's sleek profile and optimized boat-tail angle, this round delivers the flat trajectory and wind-bucking performance the .270 WSM is known for.
The Slipstream tip features a hollow core inside the polymer that allows fluid to enter upon impact and build pressure for controlled expansion, even at lower velocities. This unique hollow-cavity design initiates expansion around 200 fps slower than comparable bullets, making the Terminal Ascent effective whether you're shooting at close range or pushing 600+ yards. The polymer itself is heat-resistant and won't deform during flight, breaking free only on impact.
Yes. The bonded lead core and solid copper shank provide deep penetration and 90 percent weight retention even at close-range, high-velocity impacts. At the same time, the Slipstream tip and optimized ballistic coefficient mean reliable expansion at lower impact velocities downrange. This combination lets you confidently take shots from 30 yards to 600+ yards without worrying about the bullet either failing to expand or over-expanding.
AccuChannel grooves are cut into the bullet shank with a sloped design rather than the traditional 90-degree cut. This reduces barrel wear, improves accuracy across a range of rifles, and minimizes wind drag during flight without sacrificing ballistic coefficient like conventional grooves do. It's a refinement that gives you the accuracy benefits of grooved bullets while maintaining the flat trajectory and extended-range capability you expect from Terminal Ascent ammunition.
The .270 WSM performs well for deer hunting out to 600 yards and elk hunting out to about 500 yards under most conditions. With a quality bonded bullet like Terminal Ascent, which maintains energy and penetration across varying ranges, your success depends more on shot placement, rifle accuracy, and your ability as a hunter. The 136-grain load provides solid velocity and energy for these hunting scenarios when matched with proper shot execution.
