I shot several partridges in England abour 50 years ago, when I was a boy, with some 12 bore cartridges with No 10 shot that an Italian visitor gave me. Well, OK for songbirds like they shoot in Italy, but these partridges were riddled with shot so as to be uneatable. You know when a large cloud of feathers lingers on the morning breeze, that bird is not a good eating bird.
