Bill, those quail, dove, snipe and chuckar are all very small.

Not sure if you have those animals down under.
A lot of people argue that a 20 ga game load performs about the same as a 12 ga target load. I do indeed shoot fine with 12 ga target loads, even 20 ga target loads.
I am intrigued by the weight savings going to the 20 ga. I lug this for miles and miles on a good day.
