Quick Answer
The .280 AI is a long-range cartridge that stacks up well against other popular options, offering a balance of flat trajectory, moderate recoil, and versatility in hunting and target shooting applications.
Cartridge Comparison
The .280 AI (Ackley Improved) is a 7mm cartridge that sits between the .243 Winchester and the .308 Winchester in terms of performance. With a typical bullet weight of 140-160 grains and a muzzle velocity of 2,900-3,100 feet per second, it offers a flat trajectory and moderate recoil. In comparison, the .308 Winchester has a slightly heavier bullet weight (155-180 grains) but a lower muzzle velocity (2,700-2,900 feet per second), while the .243 Winchester has a lighter bullet weight (80-100 grains) and a higher muzzle velocity (3,000-3,200 feet per second).
Hunting Applications
The .280 AI is an excellent choice for hunting medium-sized game such as deer, elk, and pronghorn antelope. Its flat trajectory and moderate recoil make it suitable for long-range shots, while its moderate bullet weight and velocity ensure effective penetration and expansion. In hunting applications, the .280 AI can be loaded with a variety of bullet types, including traditional softpoints and more modern, controlled-expansion designs.
Ballistic Performance
One of the key advantages of the .280 AI is its exceptional ballistic performance. With a ballistic coefficient (BC) of around 0.5-0.6, it can maintain accuracy and trajectory out to 1,000 yards or more. This makes it an excellent choice for target shooting and long-range hunting applications. Additionally, the .280 AI can be loaded with a variety of bullet types, including those with specialized coatings and designs that enhance accuracy and performance in windy and high-altitude conditions.
