High volume shooting is typically associated with dove and pigeon hunting. These species can be hunted nearly all over the world, but some places are legendary.
Where there is agriculture, there are doves, and there’s a dove hunting season in almost every US state, but Texas is the king of them. If you’re thinking of truly great shooting though, Argentina dove hunting is the stuff of legends, with Uruguay and Bolivia being arguably just as good. Exceptional shooting can also be found in Mexico, Africa, and Europe.
