So ordered a new turkey gun today. Winchester SX4 28” 3.5” chambered 12ga. Shoulder doesn’t like the 10ga anymore. My question is does anyone have a choke suggestion for this gun? Primarily have shot 2oz #5s in a 3” 12ga my son uses with a .670 Kicks GT choke. I also have a .660 Jellyhead. Obviously I will pattern it myself, just wondering on everyone’s take on the 3.5” vs 3” differences. Kicks recommends the .675 for 3.5”. How much difference do you think it will make .670 vs .675??
