My personal best practices is throwing all the brass in a tupperware tub, spraying with alcohol/lanolin mix, and then sizing after the alcohol evaporates. I've found it to be extremely consistent from piece to piece and from loading session to loading session. Enough spray gets inside the case neck that it keeps things running smoothly. Part of that also is that I've got my dies set to where there is not a large amount of inside neck expansion so I don't need heavy lube inside the neck.
The whole process takes essentially no time at all and when it comes time to feed the press it runs super fast. I do all my processing on Dillon progressive presses, whether bulk 223 trainer ammo or precision match ammo.
