The Swift A-Frame .338 caliber 275 grain bullet is built for serious big-game work, and it has the construction to back that up. It pairs a soft semi-spitzer lead nose with a pure copper jacket and a bonded core, so the front end opens up while the rear stays locked in place. For handloaders feeding a .338 Win Mag, .340 Weatherby, or one of the larger .338 cases, this is the kind of projectile you reach for when the animal on the other end is tough, heavy, or potentially dangerous.
The magic is in the dual-core layout. A frame of copper separates the front and rear lead sections, which lets the nose expand aggressively while the protected rear core drives straight through bone and muscle. Swift bonds the lead to the jacket with their own process, and the result is a bullet known for roughly 2.2x expansion and weight retention north of 95 percent. The semi-spitzer nose is shaped to shrug off recoil battering in the magazine, so your rounds stay true tip to base even under the stout recoil a .338 generates.
At 275 grains with a .338 diameter, this is a heavy-for-caliber pick that shines on elk, moose, big bears, and plains game. It carries a G1 ballistic coefficient of 0.469 and a sectional density of 0.344, which is exactly the kind of number you want when penetration matters more than flat trajectory. Published load data covers a wide spread of .338 cartridges and powders like H4350, Reloder-26, and Ramshot Hunter, so there's plenty of room to tune a load for your rifle. Keep in mind this is a component bullet, not loaded ammunition.
For hunters who want one bullet that performs the same whether it hits close up at full velocity or stretched out downrange, the A-Frame has earned its reputation over decades of field use around the world.
This .338 diameter bullet works in any cartridge using .338 caliber projectiles, including the .338 Winchester Magnum, .340 Weatherby Magnum, .338 Lapua, and similar rounds. Published load data covers a wide range of .338 cartridges with common powders like H4350 and Reloder-26. Always start low and work up using current published data for your specific cartridge.
This is a component bullet for handloading only, not finished ammunition. You'll need brass, primers, powder, and the proper reloading equipment to assemble complete cartridges. Each box contains 50 projectiles.
The heavy 275 grain weight and bonded A-Frame construction make this a strong choice for large, tough animals like elk, moose, big bears, and plains game. It's designed for deep penetration and holds together on heavy bone. Swift's A-Frame line is known for controlled expansion around 2.2x with weight retention above 95 percent.
The A-Frame uses a copper frame that separates the front and rear lead cores, letting the nose expand while the protected rear core keeps driving for penetration. The bonded construction prevents the jacket and core from separating on impact. That combination gives you reliable expansion and high weight retention even at close range or on big animals.
