I've only taken a couple deer but this is what my father and grandad taught me. My grandad was a live off the land type of a guy who lived in a log cabin he built himself and hunted with a Browning a5 shotgun that's taken over 100 deer. When I would go with my dad as youngin we would wait sometimes up to 30 minutes before retrieving a deer. Unless it was visible and down for the count. In va our hunting laws and private property laws are very open, you can hunt with anything thing 30 cal and above for rifles and pistols as long as your county allows pistol hunting. In fact my first deer was taken with a 460 s&w 8in. I would really be interested in trying hunting with a colt walker
