I always felt Campbells work was definitive. He did enough patterns to show specifically that you will have holes in the pattern. Important enough that he developed the over the top pellet addition to eliminate the likelihood of the hole in the pattern.
I shoot over dogs.
I buried a dog that had pellets in her back.
Im not shooting spreader shells around dogs.
Campbells determination to develop 99% confidence in a spreader loadWas quite rigorous. Hundreds of patterns. It was all posted here.
I have no idea why some of you wish to perseverate on the matter.
