I also participate in SASS, alias is Macon McLeod O'Smoke. I shoot in the black powder class of Frontiersman since I also shoot cap and ball revolvers. On stage at a recent monthy shoot, the setup was down in a recessed area lined with trees all around you, meaning no wind to blow through. You started off with double tapping five rifle targets left to right for a total of ten rifle, put down rifle with action open, pickup shotgun, shoot two rounds at knock down targets. I shoot a 44mag rifle loaded with 30gr. FFg Goex, 12gauge shotgun with shells loaded with 3drams FFg Goex. I now have the smoke from 10 rounds of 44mag, and two shotgun shells lingering in the air. You now move down range to a marker, load shotgun, shoot two more knockdown targets. Move down range again, put down shotgun, draw pistols. 10 pistol rounds, five targets double tap, left to right. My pistols are 1858 Remingtons, loaded to the max of 30gr. 3Fg. I had the bay so full of smoke that everybody was coughing and hacking, everything smelt like fire, brimstone, and sulphur, and it took several minutes before the next guy got up to shoot because he complained he couldn't see. As I moved down range, from marker to marker I had to walk through a thick smog of black powder smoke. Most people ran to the markers, I just strutted like Clint Eastwood would do in his Westerns as he took out the bad guys. So the affects of black powder smoke slows your walk down to a strut, and gives you a feeling of toughness, while making those who are girly men cough and hack and complain. It seperates the men from wusses.
