Some think the 20 is perfect with 7/8th, 16's with 1 and 12's with 1 1/8th. Old school perhaps, but I happen to be one of them.
The fact they can stuff 1 1/4 into a 20 doesn't necessarily make it better. Especially when you make a 20 at the weight it should be.
Bore diameter pretty much determines what load is perfect for that gauge in giving full even patterns. With the 16, 1 ounce is where it shines.
