Lots of folks toss out distances like 40 yards - few have ever patterned their loads. It takes a pretty good choke to make the typical 20ga 1 3/8 oz payload hold together for 40yds.
Truth.
It's only been since the advent of HTL shot in smaller sizes and the Longbeard XR that any 20 gauge carried sufficient pattern density past 30-couple yards.
We're running the old skool Federal Heavy 7's in our tricked-out 20's and they are the SCHIZZ to a good piece past 40 yards.
