I'm not trying to stir up trouble: I'm trying to stir up an honest conversation.
I believe that at some point, be it 130, 140, 150, 160, 170, 180 whatever, there's no longer any doubt that a 10" pattern is SUPER effective at 40 Yards +/-5. After that point, whatever it is, the push to keep increasing those 10" circle numbers is moving the goalpost out past 40 Yards. It's just a matter of physics.
If we are going to say that 40 Yards is the ethical limit for taking shots at Turkeys, then why don't we focus more effort on increasing the total 15" or 20" circle numbers, which gives us a more forgiving pattern with room for aiming error, rather than trying to get 350 in a 10" circle, which doesn't allow for aiming error, but sure does increase the maximum effective range out past 40 yards?
I believe we need to drop the 10" circle, in favor of a larger patterning standard. The chokes and shells have surpased what needed to be accomplished in a 10" circle, and now people have started to believe that their turkey gun is a rifle. If we're going to stick to 40 Yards, let's evaluate patterns out to 15" or 20". The chokes and shells will do it.
