I'm still pretty much a noob at casting. Have been using a 6 cavity Lee for RN .45 ACP, lubed some with LLA, and some with just JPW......I'm liking the JPW since it's not as messy as the LLA. I've cast about a 1000, and lubed about 250 with JPW.......how long with the JPW lube stand up? I seem to remember reading in a post about JPW become brittle with age, can I lube with JPW now and it still be viable 6 months or a year from now? If not if I want to pre-lube is there something else I should use?
