Description
Swift built these rounds for serious work. The A-Frame 300 grain hollow point expands predictably while retaining 97% of its weight, which means the bullet holds together and drives deep through whatever you're hunting. At the listed velocity of 1,346 feet per second, these rounds pack real punch in a revolver platform.
A-Frame Design and Controlled Expansion
The engineering here is what sets Swift apart. The A-Frame features a bonded front core paired with a copper-jacket and interior partition that isolates a lead shank. On impact, the nose mushrooms back while the rear section bulges forward, creating a consistent 1.65x expansion profile at moderate velocities. The bonded construction keeps the core intact so you get deep, predictable penetration instead of the bullet falling apart.
Why 300 Grain Makes Sense
This weight is the sweet spot for .44 Magnum revolver hunting. A 300 grain projectile in a .44 Mag moves fast enough to deliver energy but heavy enough to retain velocity across reasonable hunting distances. The load here runs 1,346 fps, which gives you solid terminal performance on everything from medium game to defense situations. You get enough power without needing something that requires a cannon to shoot comfortably.
Real-World Performance
Swift's been making bonded bullets for decades, and their track record shows it. The A-Frame holds together on heavy bone, expands even when velocity drops below optimal, and maintains momentum to reach vitals. Twenty rounds per box means you're getting a full supply for testing and hunting seasons without breaking the bank on specialty ammunition.

Frequently Asked Questions
How does the Swift A-Frame design compare to standard hollow points?
The A-Frame uses a bonded core with an interior partition to create controlled expansion instead of fragmenting. On impact, the bonded nose mushrooms back while the rear section expands forward, keeping the bullet as one piece for deep penetration. Standard hollow points often shed weight or lose their structure. The A-Frame holds 97% of its weight, which translates to more reliable performance on game and penetration through barriers.
Is 1,346 fps enough velocity for hunting with 300 grain bullets?
Yes. That velocity from a revolver platform is solid for hunting applications. The 1,346 fps load expands reliably at impact while maintaining the weight retention you need for penetration. Real hunting rarely requires extreme velocities. The energy delivered by a 300 grain bonded bullet at this speed is plenty for medium game and is what makes this load useful for both hunting and defensive work.
Will Swift A-Frame ammo work in all .44 Magnum revolvers?
A-Frame ammunition is specifically designed for revolver platforms like the Ruger Redhawk, Super Blackhawk, Smith & Wesson Model 629, and similar big-bore revolvers. The 300 grain load with standard dimensions functions in any properly maintained .44 Magnum revolver. Always verify your specific firearm is in good working order and chambered for .44 Rem Mag before use.
What makes this ammunition suitable for hunting?
Swift built the A-Frame for exactly this purpose. The controlled expansion and deep penetration work across a wide range of velocities and game sizes. Combined with the 97% weight retention, you get reliable terminal ballistics and accurate shot placement. The 300 grain projectile carries enough energy downrange to deliver results on deer, hogs, and similar game at practical hunting distances.
