6.5,
I have been using the 120/123 Amax for several seasons in both my 260AI and my 264 Win mag. The 260 pushes them at 3100 and the 264 at 3300. I have shot antelope from 250yds to 488 yds. This year I have killed 3 antelope with the 120 amax. I was concerned about the shot at 488 but it was a bang flop. The bullet entered the left shoulder and exited the right shoulder and the exit was about 2" in diameter. the closer shots also did the same. The bullet is extremely accurate from both the 260 and the 264. I would not hesitate to use it on deer or elk (with the right angle on elk). IT performs as well as I could ask for.
Bill
