Swift A-Frame Rifle Ammunition .338 Win Mag 250 Gr 2570 Fps 20/Ct

The Swift A-Frame .338 Win Mag 250 grain rifle ammunition delivers controlled expansion and deep penetration for hunters pursuing medium to large game. Loaded to 2570 fps, these rounds combine the proven A-Frame bullet design with magnum-class velocity, making them well-suited for hunting scenarios where reliable expansion and consistent performance matter. Each box contains 20 rounds.

A-Frame bullets are engineered around a dual-core design that separates expansion from penetration—the front core mushrooms in a controlled manner while the rear core remains intact, driving deep into the animal. This architecture is what gives the A-Frame its reputation for consistent terminal performance across a wide range of game sizes and shooting distances.

If you're hand-loading for your .338 Win Mag or stocking factory ammunition for a dependable hunting load, the Swift A-Frame offers a balanced approach: it expands reliably without fragmenting, and it penetrates deep enough to reach vitals on larger animals. The 250-grain weight is a natural fit for the .338 platform, splitting the difference between velocity and momentum.
