Hi, my apologies if this is a dumb question. I've just started swaging 22lr hulls into .224 bullets. After derimming and annealing, the jackets turn a dark greenish color. From what I understand, this is the formation of scale from the annealing process. Do I absolutely need to clean this scale off? I'm asking because I kind of like the color, as opposed to the shiny brass color it becomes after cleaning:
(top is not cleaned, bottom is cleaned)
Will it hurt anything if I leave the brass the dark green color and shoot it that way?
