Ding Ding Ding and folks we have a winning question!! Same one entered my smoking brain last night! Say I went for my favorite High shoulder shot (with firearm)? Not a very liquid environment there if I went high just going for spine. Just dense muscle tissue and bone. Now granted an animals body isn't like a bag of blood but the organs and arteries provide a pretty liquid source for hydraulic operation but a shot like a high shoulder wouldn't provide very much liquid. Not if I went about 2 inches higher than normal anyway.
