Stan;
Yes some of those shots at late season doves could for sure exceed the three criteria.
I am though of the personal opinion that shot stringing has been blown way out of proportion to its actual affect on efficient shooting. As I recall figures show that at least 75% of the shot are in the front half of the string. Assume you start with a shot string 12 feet long at 40 yards & with some of the shot sleeves and/or buffers you reduce it to 10 feet. This is a reduction in length of more than 16%. This however in no way means you have a 16% more effective load. That last two feet of the string likely contained no more than 5% of the charge. They were the badly deformed laggards & flarers which were ineffective. These shot have been brought forward into the pattern but that important front half of the string has likely not been increased by any significant amount, but a string reduction of 16% does indeed make good advertizing.
When those three conditions are exceeded about all we can really do is "Use Enough Gun". This is why under those late season conditions you leave your beloved .410's at home & take more gun.
