I use a 20ga SKB O/U choked mod over full. I like the Fiocchi golden pheasant loads and carry 6's and 5's in my vest.

Usually use 6s in mod barrel and 5s in the full barrel.

Unless the wind is up, then 5s in both.

The only time I carry a 12ga anymore is if shooting steel for mixed bag hunts or waterfowl.
