I've found that running hot wort into a 50' 1/2" coil submerged into a keggle filled with ice doesn't have the thermal absorption necessary for 10 gallons of boiling wort. I believe the temperatures equalize somewhere around 100 deg F. The addition of an immersion chiller in the brew kettle will help, but I'd run that immersion chiller until it takes most of the heat out, then switch to the iced coil.
