I am shooting a Browning gold 3 1/2" with a browning extra full turkey choke and Winchester supreme #5's. My question is what is considered a good pattern size? I have been using this gun for three years and have patterened it a couple of times to get it sighted in but I am thinking I should pay more attention to the size of my pattern this year. Also can I shoot Hevi-shot out of my stock turkey choke? Thanks
