Cooper; Hi I have to ask; the cartridge you are speaking of; that must be made for DJ work, is that correct. While 2-3 grams will not harm the recording, 6 grams will most definately take some vinyll! Seriously at that point I would set it at the highest point on the scale than tweak it slightly for more force, however some arms counterweights will not accept that much adjustment so now you have to place mass on the counterwieght. Maybe a nice 39$ Stanton that tracks at 2.5 grams could be an option? In answer to your question I have not encountered a gauge that goes that high.
