im starting turkey hunting this year. I dont know much about the sport as i am mainly just a deer hunter. I cant decide whether to take my 20 ga. 870 or my dad' s Mossberg 500 12 ga. I will be hunting very thick woods, so i wont have to shoot far. What do you guys think? Also, can you reccomend some good calls and complete setups that have worked for you in the past? Any advice will help!
