In the end I decided that the 6.5-06 AI was the rifle I wanted to build.The .280 AI is a fantastic blend of case capacity in comparison to its bore diameter, and is extremely efficient. In my experience, you get 7mm Remington Magnum velocities with 80-85 percent of the recoil, in a compact package. The .280 Ackley Improved may just be my favorite 7mm cartridge as an all-around choice for big game hunting, at any range.It is based on just one of several "7mm-06" wildcats, others including the .280 Ackley Improved and 7mm JRS. These last two remove the body taper, thus increasing powder capacity, and they are indeed every bit as fast as the 7mm Remington Magnum. The .280 Remington retains the gradual taper and gentle shoulder of the .30-06, and even with ...The recoil of the 7mm PRC produces 27.7 ft-lbs of energy at a recoil velocity of 14.1 fps.
