Through testing I've found things go much smoother and with less runout with a wet lube in the necks. This is especially true with a typical 308 Win. FL die and thick Federal or Lapua brass when the die neck is built for thin WW cases.
It's a pain in the ass to remove, but it makes for better ammo. I've tried mica and Imperial dry lubes, but they haven't worked as well as a wet lube.
