I'm all about anchoring critters. There are no downsides to drilling shoulders.
Yes, and if haven't shot many deer you come up with a different answer. I'll break shoulder blades at every opportunity. So what if I lose 3 pounds of meat? They go down instantly.
Pretty much. If I can hit a shoulder or two, I do. You don't lose that much meat and if the deer runs, it's a short distance.
I did hit a buck in one shoulder that ran about 70-80 yards, but he still died in seconds.
