Just returned from a deer hunt, where I used my 243 AI and the 105 A-max (3177 muzzle velocity). It turned out to be a great test for the bullet, since I shot a coues deer (small sub-species of whitetail) and my buddy shot a large bodied mule deer with it. My shot was broadside at 310 yards. According to my charts the bullet is doing 2656fps at this distance. The deer ran ten feet before dropping. There was a 3/4" entrance wound and a 1-1/4" exit. The heart, lungs and liver were all severly damaged. My buddy shot the mule deer at 615 yards. Again according to my charts, the velocity at this distance was 2192 fps. The buck dropped in his tracks. The round entered where aimed, which was a high shoulder shot. The bullet made about a one inch entrance, through the shoulder plate, then through a rib, sending pieces of bone all through the chest cavity. The bullet destroyed the top of the heart and lungs, broke a rib going out, then left about a 1-1/2" exit. I was very impressed with the way the bullet performed on two very different deer at different velocities.
