Perhaps you guys can help me out on this one....

What is the difference in patterning and shot string between firing 1oz of a particular size shot(let's say 7.5's) from a 12 gauge that throws a consistant 30" pattern at 40 yards, versus a 1oz payload of the same size shot from a 20 gauge that throws a consistant 30" pattern at 40 yards?
