The AirForce Texan line of air guns are amazing for power and accuracy. With that said, the need to take the time and tune your gun to each bullet weight and varying fill pressures and hammer strike with the power wheel will be critical to getting your gun dialed in. This test is with a prototype 360 grain boat tail flat nose bore riding bullet. I was getting 2 inch to 2.5 inch groups at 100 yards. Not going to win any competitions with this - but every one of these shots would put meat in the freezer. Also - here is a 100 yard shot group with the .308 Texan with 154 gr. Spitzers from Hunters Supply.
