I recall reading an article in Outdoor Life when I was a kid (they had just invented paper back then...when I was born the Dead Sea was only sick 

 ).
Anyway, some F&W service contrived to take paper plates to the field and ask hunters to volunteer to shoot at them at increasing range until they missed one shot.
I was totally shocked to find that the average was 18 yards!!!!!  No I did not miss a zero.  Actually they had to change their test from starting long and working in.  They were surprised also.  Today with a lot more experience under my belt (much at public, L.E. and Military ranges) I dont doubt that as much.
OTOH, I would be greatly shocked if the "average joe" who subscribes to this list could not multiply that range by 5 or even 10 times.
