Federal .270 WSM ammunition (part no. P270WSMTA1) loads a 136-grain Terminal Ascent for big-game hunters who want confirmed, repeatable terminal performance. Federal has been a top American ammunition maker for decades, and this loading reflects the same attention to consistency found across its premium lines. A mechanically locked bonded core and Slipstream tip keep this bullet expanding reliably from close range clear out to velocities where cup-and-core bullets stall. Nickel-plated-brass-cased and 20 to a box, it is built to feed reliably through bolt guns and semi-autos chambered for the cartridge. In our rifle ammunition lineup, this .270 WSM loading is a confirmed, dependable choice worth adding to the cart.
Key Specifications
- The chambering is .270 WSM, a short-action magnum that matches .270 Weatherby Magnum ballistics from a compact case.
- The bullet weighs 136 grains, setting the balance of velocity and downrange energy this load is tuned for.
- The bullet is a Terminal Ascent, the projectile Federal chose to load behind .270 WSM.
- A mechanically locked bonded core and Slipstream tip keep this bullet expanding reliably from close range clear out to velocities where cup-and-core bullets stall.
- Cases are Nickel-Plated Brass, resisting corrosion and feeding smoothly, with the finish easy to spot in a dark magazine.
- Each box holds 20 rounds, enough to confirm zero and still have rounds on hand.
- At about $3.31 per round, the price reflects the bullet construction loaded into this round.
- The box ships at about 1.48 lb, handy for estimating freight on a bulk order.
- Federal engineers the jacket to hold together at both close-range magnum velocity and reduced long-range impact speed, which is what lets one loading cover near and far shots without switching ammunition.
