After watching the video of George Digweed breaking clays at more than 100 yds I came to the personal decision that patterning was mostly irrelevant waste of ammo and time. I have never seen a pattern which would indicated such shots were regularly possible with lead shot. I have also experienced shots from skeet choked barrels which broke clays at 50 plus yards which reflects the central core of the patterns are pretty thick even with open chokes. So my theory is to see if the combination of gun and shell works and don't buy anymore of those which don't. I will shoot at a patterning plate for point of aim verification.
