Tikker -
Dave, my hunting buddy, took his first elk with a neck shot. "Hank" now hangs on his wall. It was a one-shot, drop-straight-down affair.
Never cared for neck shots myself, and I counseled Dave against them. His second elk was also taken with a neck shot. Dave, a bow hunter, had dropped down into cover after the shot and lost sight of the elk. He was sure he had hit it but there was no blood trail. It had run off, mixing its tracks with those of the other 20 or 30 elk in the herd. Five of us hunted for the elk but we didn't find it until the next morning. Even thuh daytime temps were in the 20's and nighttime temps were below zero, the meat had already started to spoil - the hide is a wonderful insulator.
If you don't want to waste meat, I recommend a behind the shoulder shot. Unless you like rib bones. I've been using that shot since 1982 and have not had to track any animals - they either go straight down or they don't go very far. Only a coulpe have made it more than 15-20 yards and I don't think they made 40.
