You guys put way too much thought into this. Back in my younger days I learned real quick that a single 40 grain American Eagle .22 LR bullet tight behind the shoulder is about the cleanest kill possible on a deer. Some shots were in excess of 100 yards and it was always the same result. Instant death. Did it quite a bit on a couple ranches owned by buddies.

FYI I haven't done anything illegal for over 14 years now so don't even go there.
