I know Jimmy likes Qmaxx black for cleaning and lubing his choke tubes, but I have not read here where he comments about using this for general lubrication of shotguns.
Last season I spent a little time talking to a guy from Qmaxx at a big shoot. He was very nice and answered all my questions. After some discussion I realized that he was recommending Qmaxx for general cleaning and lubrication for all parts of any shotgun where you normally use oil or grease.
For whatever reason I had the idea that Qmaxx was great for most all lubrication of semi auto shotguns, but not so much for break open guns. I have been using it exclusively for a few years on my SA guns. So I asked him if it was good lubrication for the high stress areas of an o/u, like the hinges. He said it works great for this. He went on to say that grease gathers dust and carbon which is a much less problem with Qmaxx.
I met another customer at the booth that confirmed he had been using Qmaxx for years on all his competition O/u guns and likes it better than other cleaners and oils, and greases.
This is Jimmy’s page. I am not trying to speak for him. This is just my opinion and experience with a great product. I like to promote things that are as good or better than they are advertised, like Muller chokes.
