The very first bow I ever hunted with was a bear. It belonged to my farther. Thankfully I never shot it at a deer. Cave men were better equipped than I was that year.
I shot it often and it was dead on but I pictured the deer doing an "olay" like a matador as it was terriblly slow. Not the quietest of bows either but then again it is probably damn near as old as I am.
