Agree, Stan. And "longest possible" . . . if I'm shooting recreational skeet with a double that has a pretty tight 2nd barrel, I'll let the low singles from 6 and 7 get WAY out there before taking a shot. If we're talking competition, obviously depends on how quickly you shoot. You're supposed to take the birds in the middle of the field, but some guys are quicker than that and some are slower. But there are definitely some that are shot a lot closer than 21 yards.
