I think water wouldn't be that bad of a idea. Once your done sorting, shake them dry and hit it with a hair dryer for a couple of minutes. Leave out in the sun for awhile and then a tumbler. Only do it once so the extra work wouldn't be that bad. Most of the time is waiting or doing something else. I do think it would pay dividen's in the end. We lot sort our powders and check bullets for weight and ogive length. First person that does it should weight sort 100-200 and then check volume with fluid. See if weight sorting equals fluid weighting or see if it doesn't. IF it matches then weight sort (easier), but if it doesn't then maybe more thought needs to be put into fluid sorting :-\ :-\ :-\
