Gonna try some 6mm/223. Never necked anything up, or down for that matter. Does your lube procedure differ from normal resizing? I've been using dillon spray stuff so far and getting along fine. I know most of you will probably tell me to throw it away but so far, not bad. I realize it may not up to this task. How much of whatever you use do need to make sure gets inside the neck?
