Recently with family commitments, I haven't been able to shoot as much as I would like, honestly not much at all. I told the wife that if I don't spend time shooting, I might as well not go out. On the last day of archery season, I miss judged the distance to a real nice 10 point and shot just under his belly. Upon reflection of the shot, I had realized that I had made a couple mistakes that I need to rectify before heading out to hunt next year. I just feel it is my ethical duty to shoot as well as I can to make a quick, clean kill. My grandson is 5 now, loves to do all things hunting with me, so I am buying him a bow for Easter. I know that his eagerness will get me shooting and plan to take him to several 3-D archery shoots to help with judging distances. I'm looking for some mental checklists you all use to establish a routine for shooting and judging distances accurately. I would greatly appreciate it. I have one that I have used in the past, but I know that many of you on here shoot year round and have very well developed routines that I hope you're willing to share. This information could come in real handy for those beginners here on the forums as well. Thanks for all of your help.
