I USED to do this . I found I am to lazy to put the effort into it. I did NOT find any of the claimed benefits of molying MY bullets. It took several hours to moly/wax coat the bullets. Then there was the cleaning problems getting the layers of moly, powder residue and bullet fouling out of the bore. I had to ADD some powder to regain the lost FPS and rework the loads to refine the accuracy. I even tried moly on cast bullets. I did NOT try MS MOLY spray though. I can't see how spraying the nose of a bullet could be of ANY use when the base ( that part INSIDE the case) is where the bullet rides in the grooves. Seating and pulling several bullets showed that little of the moly stayed on the bullet BUT HEY< don't let my findings prevent YOU from trying. I'd just use the $$ for molying to buy additional components.!
