they tend to run directly in the direction they were facing when shot..... This fact is the source of many a "charged by a b'ar" tale
I've found this to be true BUT, "most times" they only run "that" direction for a short distance, and then circle to where they have decided to go..
I shot a brown bear one time as it was comeing straight at me. It would turn slightly every few steps and show it's left shoulder, so i broke that shoulder with the bullit slightly quarting away and exiting. At the shot the bearturned 180 and ran as i hit it a second time anchoring it.
