I hear tons about the 22" 20 gauge, in fact I have one, but I've never heard from anyone mentioning the 12 in the same length and choke. I know it would be a stomper but given a little creative light reloads it could be a versatile little shotgun. An acquaintance who reloaded 7/8 oz shot in 12 gauge at normal velocities once said that the 12 made the best 20 gauge and in our little singles the 12 would be lighter.
