Snug it up close to that shoulder or if he's close... right through it.
If he's one of those monster 400-500 pound jobs...
don't be hitting the shoulder. I'd use a cut on contact
I think. This eating size hog was shot by me years ago
with a slow boat to china recurve at probably something
like 175 fps... Bear Razorhead(the old ones) with a clean passthrough.
It did pass through the offside shoulder.
