Swift A-Frame Heavy Rifle Bullets .458 cal 400 gr AFSS 50ct

Description

When you're loading for big-bore cartridges that put you nose to nose with the toughest game on earth, you want a bullet that holds together no matter what it hits. The Swift A-Frame Heavy Rifle bullet in .458 caliber, 400 grain, is one of the names serious handloaders reach for. It pairs a bonded front core with Swift's signature cross-member wall that divides the bullet, letting the nose mushroom wide while the protected rear core keeps driving forward. The result is reliable expansion and the kind of deep, straight penetration that matters when the stakes are high.

What Sets the .458 A-Frame Apart

The design starts with a jacket of pure copper, not alloy, wrapped around a lead core that's bonded in place so the front end won't come apart on impact. That internal cross-member acts like a wall between the expanding nose and the solid base. Swift builds these to start opening up around 1,650 feet per second and to stay together even past 3,000 feet per second, so whether you're running a mild load or pushing it hard, the bullet behaves predictably. Expect roughly 2.2 times caliber expansion and 95 percent or better retained weight.

Loading the 400-Grain Swift A-Frame

This 400-grain weight in .458 covers a lot of ground. It's at home in the .458 Winchester Magnum, .458 Lott, .458 SOCOM, and other big-bore cartridges where you want controlled expansion without giving up penetration. The flat-nose profile carries a sectional density of .272 and a G1 ballistic coefficient right around .258. Always work up loads using current data from a trusted manual or the powder maker, since Swift bullets can run differently than cup-and-core projectiles of the same weight.

For hunters chasing Cape buffalo, big bears, or anything else that can hunt you back, the A-Frame has earned its reputation over decades of field use. It's a premium bullet that rewards the handloader who wants terminal performance they can count on.
