hey guys i usually dont gun hunt deer but so far this year they havent been within bow range and with gun season right around the corner i thought i would get out my father in laws old marlin lever action 30-30 that is scoped and pack it , leaving my 30-06 in the closet, how should i sight this rifle in? ill be hunting thick woods with maybe the longest shot being less than 100 yards ( doubt i would take that long of a shot in the woods) thanks!
