Lately I've been shooting at the local indoor range with my cast boolits, and noticed all the smoke from the lube. Don't notice it much when outdoors shooting. I'm using carnauba red with unique powder. The exhaust fans seem it suck the smoke back towards me, and don't really like to breathe all that smoke. Does anyone have any suggestions, maybe change the powder. A friend of mine uses 231 and I see lots of smoke coming from his as well.
