Here is the question.
Have you ever taken out a pigs shoulder, penetrate, the area between, and had one run?
No. I try to avoid that shot, because it does this:
... and I really like to eat shoulders.
The only "behind the shoulder" shot I've taken on a hog was with a .223, and the 64 grain soft point dropped him right there. The same bullet in the ear is deadly, too.
I hunt hogs for meat, however. If I were trying to cull them from an area, I'd have no problem with shoulder shots.
