Hi, I keep my revolvers in gun muffs stored in my gun safe. Before storage I juice up the revolver with Ballistol. I have noticed that the brass on the stored revolvers is getting dulled. The dulling is superficial, but it looks ugly on the revolver brass. I speculate that the Ballistol that can remove copper from bores is the culprit, eats the brass. Because of this problem I may use WD40 to surface protect my revolvers when stored in the future.
Regards,
Richard
