I have purchased a Win Super X2, 3 1/2 chamber with a 26" bbl. I am looking for help on where to start with turkey chokes and loads. I was considering using either the new Hevi 13 or the Win Extended loads in 3 1/2" From what I have been told the older Hevi 13 liked to be choked down but have any of you tested this stuff yet to see if the new loads were the same way?
