Buy a little bottle of liquid lanolin, 99% isopropyl alcohol and a spray bottle. Mix 10:1 ratio with lanolin being the 1. I throw an old bullet in the spray bottle to aid in mixing.Mind sharing the recipe and how you use it?
I spray the cases in a plastic bowl, work with hands (use gloves) and let dry for a couple minutes. Works great. As usual, not my idea. Learned it from some old timers
