Does everyone lube their brass AND bullets? Just one or the other? I'll be using carbide dies, so I know you don't have to, but probably a good idea. Now how do you physically do it? I bought some of the one shot spray stuff. DO you just spritz them in a container, or take each and roll them around on one of those lube pads? Does the lube build up and cause gunk in your feed tubes? I'm going to use the Lee auto brass and bullet feeders.
