Yeah buzz,
Many of my friends use them, but I don't care much for it. Probably because I am loathe to use a repeater. I just prefer double guns, and don't like them camo'ed. I own one repeater that is in usable condition, a black 390 that I use for ducks when the conditions are just terrible.
If doves are coming from a particular direction all you have to do is keep the muzzle pointed in that general direction and there will be no reflection. But, when they come from all points of the compass bets are off. I can't tell you the times I have seen gun barrels reflect like a mirror, and actually seen doves turn, at a great distance, and go another direction.
