I have a distinct privilege of being allowed to hunt with the owner of a plantation that early releases quail, in August of each year. On the first hunt I am invited on I use one of my .410s. Though the birds will fly very well, they're not truly wild yet, but with the little gun I will miss more than my share.
Later in the season, when we go, I will go to the 20 bore with 7/8 oz. shot. No more is needed on any quail, wild or released, with the proper choke.
It's not 12 bores that shoot birddogs, IMO, it's dummies who shoot too low, whate'er the gauge.
As has been said by others, you honor your host's rules. Or .... "when in Rome ..........you shoot Roman candles".
