I pattern my guns depending on what type of area i will be hunting, most of my shots are over decoys and no more than 30 yards in the spring, so 30 yards is what i have patterned my gun for this year. Now in the fall when i am walking logging roads and fields i will stretch it out and will pattern the gun for 40+ unless i am walking solid timber. But no matter what i always shoot them out to 40 just to see what my maximum effective killing range is.
