I have started using Ballistol as a lubricant after cleaning. It has a couple of characteristics that I like. It does not react badly with any of the powders either black or synthetic. If some is left in the bore it will not create a bad mess with the power when shot. It also will mix with water and when mixed it stops the water from attacking the steel so if there is any traces of moisture after cleaning and swabing with alcohol which is the way I do it the moisture will mix with the oil and become inert (I use either dish detergent or laundry detergent liquid as long as it does not contain bleach) and swab with the 50/50 mix of 91% rubbing alcohol and blue windshield solvent before running a few patches of Ballistol through. I find that sometimes I have to resort to regular chemical stuff like bore cleaner to get the primer residue off the breechface of my Omega or the Huntsman as well as the firing pin holes to keep them clean.
