April 5, 2026

Quick Answer

Several states in the US allow the use of .280 AI for hunting big game, including Alaska, Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming, under specific regulations.

Hunting Regulations and Permits

In order to hunt big game with a .280 AI in these states, you’ll need to familiarize yourself with local regulations and obtain the necessary permits. For example, in Colorado, a non-resident big game hunting license costs $749, and an additional permit may be required for specific species like elk or deer. It’s essential to check with the state’s wildlife agency for the most up-to-date information.

Choosing the Right Ammunition

When selecting ammunition for hunting big game with a .280 AI, consider the bullet weight and type. A 140-grain bullet with a ballistic coefficient of 0.5 or higher is suitable for hunting medium to large-sized big game. For example, the Hornady 140-grain ELD-X bullet has a ballistic coefficient of 0.54 and is designed for long-range accuracy. Make sure to check the local regulations regarding the use of expanding bullets for hunting.

Hunting Techniques and Equipment

To successfully hunt big game with a .280 AI, it’s crucial to have a good understanding of hunting techniques and equipment. A high-quality, variable-power scope is essential for accurate shot placement at varying distances. Consider investing in a rangefinder and a wind meter to help you calculate bullet drop and wind deflection. Additionally, make sure to practice shooting from a rest to develop your skills and build confidence in your rifle.
