My go to guns are 16's and 28's. I have always thought the 16 was the classic gauge and perfect for grouse. There is just something right about the loads. I do agree about ammo - finding exactly what you want when you need it is almost impossible but there are a number of companies producing ammo virtually any combination is available. I just order by the flat and I always throw an extra couple of boxes in when I head to the grouse woods. Below is a 16 ga Parker DH, circa 1892, shooting 2-1/2" RST 7-1/2's loaded in paper hulls. (Gotta love the sound of paper hulls rattling around in the back of the vest).
