There was a range near where my dad was living in his later years and we'd go there with him...apparently there were a few patrons of whom he had a few issues with and if they happened to be there, dad would do a windage check and position himself upwind then shoot his black powder essentially shutting down the other lanes until the smoke cleared....Love the smoke and fire of the powder guns.
They tried everything for years to get him kicked out of the club or have to use firing ranges which are down wind.....finally they built a black powder only section of the range (basically just for him)....one particular day the wind was just right to blow the black powder smoke onto the other ranges....and he'd make sure he was there that day just to smoke them out....
Quite a character that old man of mine.....been gone since 2005 now.
