While traipsing through the wire grass at Morrison Pines I picked up an empty shell, it was a 3 inch 20 with 1 1/4oz of #4
I haven't used anything bigger than a 20 for quail. Admittedly I take the Purdey light game gun but the 2 inch RST are equivalent to a 28 or 20 with 3/4 oz loads. I also enjoy the 410 but it is a Fox double no repeaters
If were going to count 16's as quail guns I'll post a couple.
