A sprinkler is disclosed for improved flow characteristics. The sprinkler has a sprinkler head rotatably supported for distributing water and defining a flow channel for directing water flow therethrough with reduced head loss. The flow channel has a smoothly tapered portion for receiving water and channeling the water towards an outlet in communication with a first nozzle for distributing the water. The flow channel with reduced head loss produces a greater throw distance at a lower trajectory with a lower flow rate and pressure. The flow channel may be formed within a flow channel member positioned within the sprinkler head. The flow channel member may cooperate with the sprinkler head to define a cavity allowing water to pass through the cavity from the flow channel for emission from a plurality of other nozzles.
