Unless you use a Carbide sizer ball, most people who use FL size dies lube the inside of the neck to keep the ball from screeching as you retract the FL or partially neck sized brass.
The effect of lube for 'consistent' release, is minimal if at all. It would be quite low on the list of items affecting accuracy and consistency in a load. The bullet release at ignition is almost instantaneous with expansion of the brass. I question there would be ANY effect.
For small necks in cartridges where I don't have bushing dies, and there aren't many I don't have bushing dies for, I use graphite in a small glass half full of #9 birdshot mixed with the graphite. Or, I do as another poster states, put the mouth of the case onto a lube pad. The very small amount of lube that transfers in the case provides sufficient lube to eliminate groaning as the expander passes. Worrying about this is paralysis by analysis!
