I don't use aerosol or spray case lubes, but on new brass I lube case mouths with graphite on a brush or necks and mouths with Redding Imperial dry neck lube and their ceramic bead applicator. For sizing, I use regular Imperial lube applied with finger tips. I worry less about mouths on fired brass, if it hasn't been cleaned and retains carbon residue inside the case mouth so long as runout remains very minimal and seating depth is consistent.
Good post. We all know we all have different routines. I personally only use graphite on a brush for application into the necks of the cases on my new die sets. I also polish the expander ball on my new die sets as well. If at any time I feel the expander dragging through the necks with too much resistance, I'll re-polish and treat with graphite again. Otherwise it is unnecessary. I rarely use it. I also don't use Hornady one shot for sizing, but it works damn well for release agent when I'm glass bedding my new to me rifles. As with anything reloading related, KISS... That is my motto.
Anything you do that is unnecessary and excessively wastes time and affects efficiency is called being stupid. I don't like stupid.. Some of you guys do.. Keep schidt simple, keep it consistent and load accurate ammo. If you are not loading very accurate ammo in a short amount of time, you are doing something wrong..
