A couple of additions: I use ATF for all of my bore cleaning and wipe downs. NEVER have a speck of rust appear. MY BPCR shooters put me on it as that is what they seem to use most of the time for cleaning and preservation.
Also, my trigger mechanic told me to never use WD 40 on my O/U triggers as it dries with a film and residue, but to use REM OIL.
