I have used Ben's Liquid Lube exclusively for the past year. I have not had any leading at all. I have only had excellent results. I've used it in the hottest heat of summer and the coldest weather of last winter. I use just one coat for pistol boolits and 3 coats for rifle boolits. It's the fastest drying tumble lube made. It's also the easiest lube to make and use.
You all need to try this BLL tumble lube for yourselves.
Thank you Ben for giving us the recipe for the best boolit lubricant ever!
