Description

The Swift A-Frame in .257 diameter is one of the most respected bonded hunting projectiles you can load. At 100 grains, it's right in the sweet spot for the quarter-bore cartridges like the .25-06 Remington, .257 Roberts, .250 Savage, and the 25 Creedmoor crowd. Swift built its reputation on bullets that stay together when it counts, and the A-Frame is the one that started it all.

What Makes the A-Frame Bullet Different

The design borrows the best idea from the partition-style bullet and adds bonding on top of it. An internal wall of copper divides the lead into a front core and a rear core, and both cores are bonded to a thick, pure copper jacket through a proprietary process. The front section mushrooms like a classic soft point while the interior wall stops expansion cold at the midpoint, keeping the rear core intact to keep pushing forward. That combination is why these bullets routinely hold onto 95 percent or more of their original weight, even after punching through heavy shoulder bone.

Why Hunters Reach for the .257 A-Frame

Controlled expansion is the name of the game here. The jacket tapers toward the tip so the bullet opens at a predictable rate across a wide velocity window, which matters when you might take a shot up close or stretch it out a bit. Expansion is held to roughly a 40 percent increase over original diameter, so you get a deep, consistent wound channel rather than a bullet that comes apart on impact. The wraparound jacket at the base locks the rear core in place and guards against deformation, and the semi-spitzer lead nose profile feeds smoothly and handles recoil in the magazine.

Loading the Swift A-Frame

There's no mystery to working these up. As a flat-base, bonded design, the A-Frame tends to shoot its best with loads running at or near maximum chamber pressure, so it pays to work up carefully and watch for the node where your rifle settles in. It's a flat-base bullet, not a boat tail, which suits realistic hunting distances just fine. For deer, pronghorn, and larger game where penetration is the priority, this is a projectile you can trust to do its job every time.

Frequently Asked Questions

What cartridges can I load the Swift A-Frame .257 100 gr in?

This bullet uses the standard .257-inch diameter, so it works in any quarter-bore cartridge. That covers popular rounds like the .25-06 Remington, .257 Roberts, .250 Savage, .25 Creedmoor, and similar. Just match the bullet to load data for your specific cartridge.

Are these loaded cartridges or component bullets?

These are component bullets for handloading, not finished ammunition. You'll need brass, primers, powder, and the right dies to assemble a cartridge. The box contains 50 projectiles ready to load.

How much weight does the A-Frame retain after impact?

Swift A-Frames are known for very high weight retention, routinely holding 95 percent or more of their original mass. The bonded dual-core design keeps the jacket and lead together even through heavy bone. That's what gives this bullet its reputation for deep, straight-line penetration.

Is the A-Frame a boat tail bullet?

No, the A-Frame is a flat-base design with a semi-spitzer nose profile. It's built for controlled expansion and penetration rather than extreme long-range flight. For typical hunting ranges it shoots accurately and performs reliably on game.
