I prefer ALG Gojuice at this time. It's non-toxic and very good.  

 Thanks! I’ll check it out. 

 I should qualify this:
I have not tested it in any extreme conditions. For normal use, I trust it. I am not sure it would trust it for extended full-auto rifle use or in temperature extremes or in really gross environments like a dessert.  

 I usually stick to Hoppes.  Never had any issues with it. 

 For me the shooting itself is a kind of meditation. When you aim at the target, hold it in line and hold your breath, stand as stable as you can, you are unable to think about anything but when you have to pull the trigger to shoot perfectly.
