Some eventually go the anti-intuitive route, that I did with sporting clays, and forget about choke all together. I use two fixed MOD chokes and just shoot them on everything, near and far. Been doing that for nearly ten years now, and am shooting the best of my life (at age 66). On close "rabbits" I'll drop in a Fiocchi Interceptor spreader load, only because "rabbits" are so unpredictable. Other than that ...............just smoke 'em.
When we shoot a station that has relatively close birds I sometimes quip "Reckon I've got enough choke for those?", in a joking way. When no chips hit the ground you know two things........ you had enough choke, and you had 'im in the center of your pattern. Both great confidence builders.
