The 2 gun lines that get shot the most ----Kreighoff and Perrazi have their own lube, and its a grease, that should tell you something. If used sparingly like you are supposed to dust will not be a factor. I hesitate to use oils of any kind unless its a dot here and there, the damage it does to wood is less palettable than a little dust in some grease
