Impact velocities were right around 2600 FPS. All I had available was a 20 yard head/neck shot. I hit him in the upper most vertabre and while it did knock the snot out of him and dump him, he clearly was not dead. Before he could get up I ran over to him and hit him in the head. That still didnt do the trick so I put one in his ribs at point blank. Just far enough away not to get kicked. The neck bone was cracked a bit but not penetrated. I didnt cut into the head area so I dont know if it penetrated the skull. Knowing how thick a mature bull's skull is, I doubt it. As far as the ribs, there was no exit and only some bullet fragments.
This was not the first moose I took with an AMAX. The other, again was not planned. I was sheep hunting and my buddy was moose hunting with his rifle. He wounded one which ran off to 441 yards. After he missed at that range, I asked him if he minded if I ended it for him because the bull was nosing into the alders minutes before dark. He said take him and I sent a 155 on the way. My mentality was shoot for the upper neck. It wont break the shoulders, may not make it to both lungs, a neck shot is either a miss or a drop. The bull dropped in his tracks. As we got closer, he made it to his feet for a few more yards where we finished him off with a head shot. Another very messy situation involving an AMAX. Again, the vertabre was fractured but not penetrated.
Having harvested several moose using a variety of bullets including AMAXs, Barnes and Nosler Accubonds, I prefer the Accubonds all the way around. The X bullet did awesome, I just prefer a higher BC bullet for the longer shots such as the 200 Accubond. Now that I use a 338, I use the 300 Berger for the long stuff and the 225 Accubonds for the close up stuff. I hate carrying two loads, but in LRH, there are very few if any at all bullets that work equally as well at 20 yards as they do at 800 yards. Unfortunately, that is our reality.
