RCG, the folks here are kidding you. Face it, the 870 in 20 Ga. is almost a blank gun for effectiveness. Please send me a $50.00 dollar bill and I'll meet you in Ashville to rid you of that useless shotgun. (I do have gas expenses)
I've killed many German Hares (think jackrabbits) with a 20 and it will roll'em if you hit'em. I've also had the pleasure of cleaning several deer killed with 20ga buckshot. Works fine IMHO!
