RE: Suggestions for an old shooter, new hunter and son
good luck to you and your son, on the field dressing issue do a search and you should be able to get enough info to get you through it, also you may want to rely on you relatives that you'll be hunting with, you'll propably need them to help you locate the animal also if you've never tracked a deer, on a good shot they can still cover some yardage..
again best of luck, and welcome to this board
