Quick Answer
The .280 AI cartridge is effective for hunting in dense brush environments, offering a balance of accuracy, range, and recoil that makes it suitable for a variety of game species. Its moderate velocity and flat trajectory allow for reliable shots at distances up to 300 yards. However, its relatively low kinetic energy may not be sufficient for larger game at longer ranges.
Ballistics and Performance
The .280 AI cartridge is based on the .308 Winchester case, but with a slightly longer neck and a .284-inch diameter bullet. This results in a moderate case capacity and a relatively low muzzle velocity, typically around 2,600-2,700 feet per second. The flat trajectory and moderate wind deflection of the .280 AI make it well-suited for hunting in dense brush environments, where shots are often taken at close to medium range. A good hunting load for the .280 AI might include a 140-grain bullet at 2,600 fps, providing a kinetic energy of around 1,500 ft-lbs.
Hunting in Dense Brush
When hunting in dense brush, it’s essential to use a cartridge that can deliver a reliable shot at close range, while also minimizing recoil and blast to avoid spooking game. The .280 AI’s moderate recoil and flat trajectory make it an excellent choice for this type of hunting. To take advantage of the .280 AI’s performance, hunters should focus on using a good quality optic with a magnification range of 3-9x, and a reticle that allows for accurate shot placement at close range. Aiming for the center of the chest or the lungs will ensure a quick and humane kill.
