Stan;
My figures were simply theory & based on a situation which doesn't exist in the real world. If the shot were distributed evenly over the entire pattern & spread linearly it would be a simple mathamatical equation to calculate on the fact the area of a circle is proportionate to the square of its diameter. The fly in the ointment is the shot are not evenly distributed. In theory if you had 100 shot in the 30" circle & you drew a concentric 15" circle then it would have 25 shot in it. You could no doubt fire a million patterns & never acheive this situation. You will virtually always have some amount of central core thickening which will increase the number of hits in the center, but lessen the hits in the outer ring. If you ended up with 40 hits in the 15" circle & 60 in the outer ring then you would have 200% central thickening so obviously a well center target coud be killed or broken at a further distance than one in the outer ring. Yet each of these two patterns could be described as a 60% pattern with 3/4oz of #6 shot.
