Well folks, I sit down against a tree in my backyard and use my sticks to steady the gun when sighting in with regular 2-3/4" #7 game loads, then when I get it dialed in poa-poi close with the game loads I clean barrel/choke and put in the good stuff 3-1/2" hevi #7 and fine tune from there, shooting at 40yrds 30 and then 20 and also cleaning the barrel/choke after every shot at ea.
Once dialed in with my turkey load I shoot it all over again only this time without the sticks and with all my hunting gear on, vest, facemask ect. just like a real live hunting situation shooting at quaker boy life turkey targets at 40, 30, and 20yards and yes cleaning the barrel after each shot here also. Usually after that I'm very confident and shure of my setup and equipment and we are all ready to go!
