For the upland birds they had available and in the conditions they typically hunted it was all they really needed. Another 1/8th oz of shot isn’t really necessary for red grouse, woodcock (not even European woodcock, that run much larger) driven pheasants, wood pigeons or anything else. They shot black grouse with the same loads, but, hunting for them was ‘sort of a comical stalk until in range, so I’m told.

Best,
