Conclusion re nobody/few, etc: Blanket statements using words like "nobody" don't work well, because there's almost always SOMEBODY who does whatever. Nobody I know/few people I know . . . those will usually keep one on the safe side. But when it comes to shooting, chokes, etc, it's worth recognizing that there's a different world inhabited by those who shoot clay targets competitively (especially sporting clays, where--unlike skeet or 16 yard trap--you can have shots at widely varying distances) and those who are more into hunting and "recreational" clay shooting.
I used to work one leg of the Wisconsin Ironman sporting clays shoot as a puller or scorer. 400 targets over 2 days, 100 each at 4 different clubs. I saw more guys changing chokes in that one event than I did the entire remainder of the year. Matter of fact, hunting and mainly shooting skeet, and sporting clays mostly at sxs shoots or with guys who shoot sxs, I might have gone an entire year without seeing anyone change chokes.
