Description

If you carry a 44 Magnum in country where something large might take an interest in you, the Swift A-Frame 44 Rem Mag 300gr is the kind of load that argument calls for. Three hundred grains is heavy even by 44 standards, and the bonded dual core A-Frame bullet is built to hold together and drive straight through heavy bone rather than opening up on the surface.

Why 300 grains and not 240
The 240 grain jacketed hollow point has been the standard 44 Magnum load since the cartridge appeared, and it is a fine deer bullet. It is not the bullet you want against something with a thick skull and heavy shoulders. The Swift A-Frame 44 Rem Mag 300gr trades a little velocity for sixty more grains of bullet and far better construction, and on big animals that is the trade that matters.
The A-Frame design does the rest. A bonded front core expands and stays attached, a solid copper partition stops expansion, and an unexpanded rear core keeps pushing. Weight retention runs above ninety five percent, so the Swift A-Frame 44 Rem Mag 300gr arrives deep with most of its mass intact instead of shedding lead on the way in.

1346 feet per second and 1207 foot pounds does not sound dramatic next to a rifle, but handgun terminal performance is about penetration far more than energy. The Swift A-Frame 44 Rem Mag 300gr has the sectional density and the construction to reach vitals from angles that would stop a lighter bullet in the first few inches.
Bear country and handgun hunting
Guides and commercial fishermen in Alaska have carried heavy 44s for decades and there is a reason the heavy hard bullets are what they choose. The Swift A-Frame 44 Rem Mag 300gr is a sensible choice for that role. It is also a capable handgun hunting load for elk, moose and hogs within the honest range of a revolver.
On deer the Swift A-Frame 44 Rem Mag 300gr is frankly more bullet than necessary, and it will often pass through with modest expansion. That is fine and it is the nature of the design. If deer are your only quarry, a 240 grain hollow point will do more visible damage. If there is any chance of something larger, this is the one to have loaded.
Honest notes before you buy
This is expensive ammunition and the A-Frame bullet is why. It is a labor intensive design manufactured in small batches. A box of twenty goes a long way in a carry role, but budget a second box for practice so you actually know where it hits.
Do not use this for home or personal defense. A bullet designed to penetrate deeply through heavy bone will pass through a human target and keep going, which is an unacceptable risk in any populated setting. The Swift A-Frame 44 Rem Mag 300gr is a wilderness and hunting load. Choose something built for defense if that is the job.
Recoil, guns and practice
A 300 grain 44 Magnum load kicks hard, particularly in a light framed revolver, and pretending otherwise does nobody any favors. The Swift A-Frame 44 Rem Mag 300gr in a four inch gun is genuinely unpleasant to shoot in volume. In a heavy six inch or eight inch revolver it is manageable and accurate. Know which one you are carrying.
Practice matters more than the load. A shooter who can put two rounds of the Swift A-Frame 44 Rem Mag 300gr into a dinner plate at fifteen yards under stress is far better off than one with perfect ammunition and no trigger control. Build that skill with cheap 44 Special or light 240 grain loads, then confirm with the real thing.
The bottom line
For bear country carry and serious handgun hunting, the Swift A-Frame 44 Rem Mag 300gr is one of the most trusted heavy 44 Magnum loads available. You can read more about the bullet design at swiftbullets.com, or browse the rest of our stock on the MAG5 Firearms ammunition page.
