Good morning all, I am a visitor to your forum with a question.Hope I am in the right place.....you people seem to be having a fun without injuries so here goes. I shoot black powder target pistols for fun whilst trying to improve my shooting, black powder pistols give off a big cloud of smoke, some flash and a good BOOM. Now.... call me sad, but I would like to add some colour to the smoke and sparks....just for fun.
The pistols run on Swiss black powder Numbers 1&2 [fine & not so fine] using charges between 15 and 30 Grains. so, is there something you can think of that I could mix in with the powder to add a bit of colour ? somthing that won't blow my guns up or realy piss orf the range conduct officer...........
Many thanks,
Marcus.
