This http://www.reefcentral.com/calc/drain.php is a pretty good calculator for drain pipe size in an overflow.
I built a test rig to measure the flow of several diameters of pipe and also got 300 gph. However, I know that Rallysman got 600 gph through his when it was new (I have enough trust and faith in him that I didn't have to ask twice).
Just know that the design/dimensions will greatly affect the flow. Use 300 gph rather than 600 in your design calculations because as the overflow ages, it will get some growth inside that will reduce the flow. Also, use two overflows that can each handle all of the needed flow. This is because if one becomes obstructed (dead fish), the system won't overflow.
