My current definition of correct is "It works." What grit? Picture of container?Boyd, it's not real scientific. I load up a bore mop screwed into a short extension on a cordless drill and do half a dozen in-and-outs. Then clean the beejeezus out of the die and size a case with it. They'll often start working better even when there's no apparent new crosshatch. I use Permatex valve lapping compound. Before you think my cheese has slid off my cracker for using something so 'gritty'...it breaks down really fast and has a very good oil based carrier.
A real dirt clod way of doing it. -Al
