Allen, good report. It confirms some of my own results using 338 AB's on Mule deer. Hope you don't mind me adding this attachment. It shows mule deer hit with a 338/180 AB and no exit hole and no bullet to recover. It shattered inside the deer. web page
I keep hearing that the AB's are supposed to behave like Partitions. Not so in my small experience.
Hope you will add to your post here and we can hear more about your hunt. Sounds like you had a great time in spite of the bullets.
