The articles I have read suggest some form of inside the neck Lube is needed after brass is cleaned using ultrasonic cleaners if the black usually left in the neck using a vibratory cleaner isn't present.
I have seen suggested a dry lube from Neco, and I do have one of the red ( hornady?) kits with 3 sized brushes and a white powder for lubing the inside and outside of necks.
Curious if those of you who are lubricating the inside of the necks have a preferred brand or method of keeping bullets from being damaged by the clean neck surface.
