When Remington marketed the 580 smooth bore with the special trap that was made for or by Remington to throw little clay birds. The clay birds would travel about 25 yards off a table, they would reach max height around 15 or so yards and were easy to break at that range. You couldn't dust them but they broke with a hit. I shoot black wood boring bees off my deck and have knocked them down at 20 yards.
