I was able to knock them down with my .177 Cyclone on high, out past 30 yards. Took a near perfect hit, though, and a heavy pellet with a fresh fill. Lots of fun, especially shooting it offhand. BTW, the Cyclone is doing just over 21 fpe with Kodiaks on high. It runs for hours on a charge, and is plenty durable. Tried to talk Mrs. Santa into putting one under our tree, but I don't think it's happening :-(. Later.
