Now hold on there, Don. I can guarantee you that there will be a whole bunch of variability between a .410 with a 1/2 oz load of 9's and a 12ga with a 1 1/8 oz load of 9's. Going back to the question of how many single pellet breaks occur, I doubt anyone here would disagree with the notion that they're far more likely to occur with the .410 (that being one reason .410 scores are lower than 12ga scores) than with the 12ga, because of the very significant difference in pattern density.
