Well I have shoot many many deer.I can pound though 2 sholder baldes with no problem. I have allso shoot pigs. Every arrow passed though them. But elk are a dif story. I never shoot long shots . I shoot angled away shots.And never have had a pass though . For that matter not any of the hunters I hunt with Have hade pass though UNLESS they shoot to far back. Than they blow right though the elk. maby tuch 1 lung or the liver and we have to track it. Mine we never have to track. I think most of the elk hunters shoot to far back.This is what i have saw.I allso shoot black bears most every year.They are eazyer to kill than than deer or elk with ever be.
