All but 2 of my deer have dropped in their tracks. They've been shot with either 7mm mag or 308, with 150 gr bullet. Last years buck went down, but after about 10 min he got up and ran and I put another shot on him and that was it. It was not the best shot setup walking up a hill, away fom me aou 150 yards away. The bullet entered right behindnthe shoulders on the left side and exited thru its neck. The second shot was thru the spine which ended it. The other was a 180 yd shot with the 308. The deer went down, but I didn't wait and as i walked up to the deer it got up and ran. Lots of blood and tracked for about 2 miles. Sadly I followed fresh boot tracks along with the blood and only a gut pile at the end.
