I shot two does today both well inside 100 yards. The first was more precise I put the 155gr bullet right in the throat. She hit the ground right on the spot. I then turned to another one that had not ran off with the others. At this point my heart is racing and I shot again. I can't say for sure where I put the second bullet but she turned and ran. This left me questioning my shot placement. I get out of the stand and go to the 1st deer I shot. When I get there she kicks so I put one in the top of her head to finish her off. When I shoot I like them dead right there and not all this flopping or moving around. I especially don't want any animal I shoot to suffer. I then turn my attention to deer number 2. Right off I can't find any blood which is not good. I new that might be a problem because of bullet design. I finally pick up the trail and as I go into the woods farther the blood trail is getting larger and larger. I get to the top of a small hill and I start finding tissue that looks like it might be from the heart. A few drops later it stops. I mean nothing anywhere. I stayed in the woods for probably two hours in the dark looking for her and nothing. No more blood anywhere and to make things even worse it starts raining. I will see if I can find here tomorrow. I know Berger makes a good bullet. They have been very accurate out of my 308 but I may have selected a bullet that was wrong for the distance I was shooting. On the neck shot it seems I had no expansion of any kind. It was just a icepick like hole all the way through. Should I go to a different bullet? Any advice would be greatly appreciated.
