Proven Construction for Big Game
The Swift A-Frame uses a divided design. The front half of the bullet is bonded and expands consistently across a broad range of velocities, while a partition-style wall stops expansion so the back half stays intact.
That intact rear section drives deep penetration even on large, tough animals, which is why handgun hunters trust the A-Frame for big game. Federal says high weight retention and controlled expansion hold up regardless of distance.
A nickel-plated case resists corrosion and helps extraction, and Federal loads the round with a specially formulated propellant and its own primer for dependable ignition.

Handgun Hunting Tips
Use Federal 454 Casull 300gr Swift A-Frame ammo only in firearms chambered for 454 Casull.
Practice from field positions and rests you will use in the woods, such as shooting sticks, a tree or a pack.
Keep shots within the range where you can hold every round in a small group on the vital area.
Velocity from your handgun will vary with barrel length, so confirm your zero and point of impact with this exact load.
Federal 454 Casull 300gr Swift A-Frame ammo is a heavy-hitting choice for handgun hunters going after elk, moose, bear and other large game.
The 454 Casull is one of the most powerful revolver cartridges in common use. A 300 grain Swift A-Frame turns that power into deep, controlled penetration, which is why Federal 454 Casull 300gr Swift A-Frame ammo is a popular pick for large game and for backup in bear country.
Shot placement matters even more with a handgun than with a rifle. Wait for a broadside or slightly quartering-away animal, and aim for the heart and lungs. A well-placed shot with Federal 454 Casull 300gr Swift A-Frame ammunition gives the bullet the best chance to do its job.
After the shot, mark where the animal was standing and give it time before you follow up. Handgun hunters often take shots at close range in thick cover, so a careful, patient follow-up makes recovery easier.
Clean your revolver or pistol after each hunt, paying attention to the cylinder face and forcing cone, where powder residue builds up with heavy loads.
Handgun hunting rewards practice. Spend time at the range with Federal 454 Casull 300gr Swift A-Frame rounds until you can place every shot on a paper plate at your planned distance, from the same positions you will hunt from. Recoil from a powerful revolver is real, so build up gradually and use quality hearing protection.
Store your hunting ammunition in a cool, dry place in its original box, and buy enough from one lot to sight in and still have plenty for the season.
