When you're handloading for a .500 S&W or another big-bore revolver and you want a projectile that won't come apart on tough game, the Swift A-Frame 325 grain sits near the top of the list. It's a .499 diameter, hollow point-profile bullet packing a bonded lead front core and a protected rear core, which is the whole reason it hits so hard and holds together the way it does.
The A-Frame borrows the dual-core, partitioned idea and takes it a step further. The soft front core is bonded to the copper jacket, so when the bullet expands the lead stays welded to the jacket instead of shedding off. That expanded front folds back and mushrooms to a wide frontal area while the rear core, kept separate behind the internal wall, stays intact and keeps pushing. The result is the kind of straight-line penetration that lets a big slow bullet punch through shoulders and still keep going.
Weight retention is where this bullet earns its keep. Swift's heavy revolver A-Frames typically expand to well over one and a half times their original caliber and hang on to the vast majority of their mass, often in the 90 to 97 percent range. For hunters loading up for elk, big bears, or anything with heavy bone, that combination of expansion and retained weight is exactly what puts game down and keeps it down.
At 325 grains with a sectional density of .186 and a ballistic coefficient of .135, this bullet is tuned for the velocity range big-bore revolvers actually run. The A-Frame is famous for performing the same across a wide velocity window, expanding reliably at slower revolver speeds yet staying together when pushed hard. Handloaders who run the .500 S&W Magnum reach for these when they want a hunting bullet that does its job whether the shot is close and fast or a bit further out.
These .499 diameter, 325 grain A-Frame bullets are designed for big-bore revolver handloads, most commonly the .500 S&W Magnum. They're component projectiles for reloading, not loaded ammunition, so you'll need brass, primers, and powder to build your rounds. Always work up your load from published data for your specific cartridge and firearm.
Swift's heavy revolver A-Frames are known for holding on to the vast majority of their weight, typically in the 90 to 97 percent range. That high retention comes from bonding the soft front core to the copper jacket and protecting the rear core behind an internal wall. It's a big reason hunters trust these on heavy, tough game.
A standard cup-and-core bullet can lose a big chunk of its weight or come apart at higher impact speeds. The A-Frame's bonded front core stays welded to the jacket during expansion while the partitioned rear core keeps driving forward, giving you both a wide mushroom and deep, straight penetration. That makes it a better pick when you need to reach vitals through heavy bone.
Yes, the A-Frame is engineered to perform across a wide velocity window. It expands reliably at the slower speeds you get from a revolver barrel yet holds together when pushed to higher velocities. That consistency is a big part of what made this design a favorite among big-game handloaders.
