Yep! Tex I have used it and blued a few guns with it also. I reload so I shoot a lot of lead bullets. IMHO I would not use it on any gun that has plastic parts because it's got ammonia in it. I say it may affect those parts. I see no problem with all steel gun. It does a fair job on lead, but Shooters Choice is better followed by Hoppes#9. That's the way it works for me.
