First make sure #3 shot is legal for turkeys in your state, it's not here in PA. You don't need it anyway, #4 or #5 will more than get it done, especially Winchester Longbeard XR shells. I've been guiding turkey hunters for 27 years, so I've learned a thing or two. Most of the info you were given is excellent. First scout, scout, scout, figure out what those birds are doing and find a good setup spot and get in there in the dark. Someone recommended a popup blind and I heartily agree, especially for a new hunter or kids, you can get away with a lot more in one of them, again positioning is critical. As far as calls, I can run all of them, however I use friction, slate / glass more than the others along with a mouth call. A good box call will also get it done, although I use mine more for locating than finishing a bird. One important thing DON'T CALL TOO MUCH!!! I know it's hard to not call to a gobbling turkey, but, when a turkey's talking he's not walking. It's real easy to cause a turkey to lock his feet 100 yds or more away and just stand there and scream. Don't yelp at a close turkey, I hear all the time that you will get busted using a slate or glass call if a turkey is close, the most I do when a turkey is real close is to purr at him if he is acting hinky to calm him down, The pot call is between my bent knees and all that moves is the bottom of the striker. I kill al lot of turkeys between 10 and 40 yds. most 30 yds or less I had a client kill a slammer at 12 yds. who had 3 other longbeards and at least 6 hens with him. Someone recommended waiting for the turkey to go behind a tree before moving your gun, this is great advice if you are in the woods, however if you are hunting a field edge, wait until the bird is in full strut and turns away from you and make sure none of his buddies are looking. You are entering into a sport that is amazing and at times very frustrating, it's not something you will master the first time or ten out, but that's part of the fun. I don't mind getting beat by a smart old gobbler, but I do mind beating myself. I hope some of this helps, so get out there and have fun. GOOD LUCK!
