Boolit lube and powder that smoke the least. Last weekend while shooting indoors some other individuals thought that I was actually shooting black powder. The range was crowded and I even saw one idiot with a shirt pulled up over his nose. My load was: Lee 356-120-TC 9mm Luger with magmas engineering hard lube and 3.8 grains of Winchester 231. Yes it does smoke a lot but it is more accurate than I can hold and I get zero leading in the bore. I am not really looking to change just because some individual shows up once in a blue moon with the box factory ammunition.
