Congrats on a great buck! I'm so happy you found him and recovered him.
I don't want to get into anything crazy here. I just wanted to add my own two cents is all based on my own experience. Starting off, 6.5mm (.264") bullets are in general very efficient and have a great BC typically, especially compared to other calibers. So even an 85gr solid like this hammer isn't terrible. Match that with your 3455fps MV, and it does better than one might think. I'm not sure what altitude you were at, so I just entered 2200' along with other typical environmental conditions. You were right around 2200fps or a bit below at impact according to my calculations. I know some will argue, but I set a personal minimum impact velocity for solid copper bullets right at 2200fps for best results, and even then a good amount of impact resistance is ideal to go along with it.
I'm not at all going to say anything about your shot other than I think we can all agree the first couple were not where desired or in an ideal location. Impact resistance in that location will be relatively low. So that's a major factor in why you got small holes in and small holes out. The damage internally was created simply by the rapid displacement of tissue and fluids as the bullet passed through.
A heavier version of that bullet might very well have increased the BC enough to retain more velocity and also experience less drift from wind. You just have to be careful you don't go too heavy and have similar issues with producing sufficient expansion. Obviously a better shot placement, preferably a shoulder shot in this particular scenario, would have been ideal. It is what it is though, and I'm not going to get into why or how the shots hit where they hit.
My conclusion overall is that the particular bullet used was just outside its limitations, unfortunately. A couple things could have helped the end result, but the bottom line is you came home with the deer and a good experience to examine and maybe learn from. Congrats again!
