I have on occasion shot steel shot at dove, but this past weekend was the first time we were required to do so everywhere (for everything). Gotta' say... Not a fan. Ducks as it turns out are a considerably easier target than are doves.... Tighter patterns and shorter shot-strings are apparently a humbling experience. I am often hunting open areas, and the birds are generally 30+ yard dipping/diving shots (which with a dove looks a lot further than it is). Seems like steel #6's run out of steam right around the 30-35 yard range. Far more pellets in the meat. And shooting a 20 gauge OU with a 7/8 oz load has considerably more recoil than a 1 oz load in the far heavier 12 gauge at the same speeds. Not at all looking forward to hunting valley quail with dove. A crippled dove is easier to find for the dog, whereas a crippled quail is a ghost. They get into rocks and thickets that no dog can get into... And hunting open ground will preclude a lot of shooting.
