If the payload and chokes are kept constant, 3/4 to 7/8 oz of premium, hard shot, slower burning powders at lesser velocity,the larger the bore size, less flyers...Right? Bore size does make a difference...or am I missing something? Flyers increase with decrease in bore size, softness of shot, and increase in velocity. Why would this not make any difference? Or is the opinion the extra bird is not killed by pellets outside the pattern? Just asking....???
