"Switch to Hevi -13 3 1/2 inch #7 shotshells and put a Indian Creek .675 or a Pure Gold .670 choke in, and you will be surprised. This is my first year shooting the Hevi's and i will never go back to lead after seeing the results from them. Im getting 290 pellets in a 10 inch circle at 40 yards out of my Mossberg 935 with a Indian creek .675 Choke."
this is a quote from a turkey hunting site.
