Was wondering if anyone is shooting a pure gold choke with the new Winchester longbeards? If so what kind of numbers are you getting? The reason im asking I tried 3.5 inch #4 out my 870 today 20 inch barrel with factory turkey/predator tube was getting 150 in ten inch circle at 40.I know that's more than adequate but was wondering if I could maybe improve a little with a more open choke.
