My preferred choke for upland birds, which for me means pheasants and quail, is light mod. Gauge doesn’t make much difference in my selection though I only own 10,12,16, and 20 bores.
My 20 is a fixed Mod that actually patterns more like a full and it’s too much. When I’m on it crushes them and will really tear a bird up inside of 20 yards if they’re centered. When I’m not on I have to shoot some of them twice due to hitting them with the fringe of the pattern.
