Swift A-Frame Bonded Features The Swift A-Frame Bonded load is built around a bonded core construction that fuses the lead core to the copper jacket so the bullet holds together under the extreme stress of heavy bone and thick muscle on dangerous game. At a muzzle velocity of 2503 fps the 300 grain bullet generates 4176 ft-lbs of energy giving hunters the authority needed to anchor large tough animals. Controlled expansion of 2.2 times its original diameter opens a wide effective wound channel while the bonded design prevents the jacket and core from separating. That combination of expansion and structural integrity is exactly what separates true dangerous game ammunition from standard hunting loads. Weight retention above 95 percent means the A-Frame bullet carries its energy deep into the animal rather than shedding mass and losing penetration partway through. The brass case is boxer primed and fully reloadable giving handloaders the option to rebuild their own ammunition once the factory loaded rounds are spent. Swift built this bullet specifically for use on dangerous game where a failed bullet can turn a hunt into a dangerous situation. For hunters heading into Africa or pursuing North America s largest game with a .375 H&H rifle this Swift A-Frame load is available for sale at GrabAGun.
