Hey all! Might be a stupid question but I’d rather ask & be sure. I was letting family shoot my 16” Tikka .308 when I noticed these embers burning in the air around the barrel after the shot I suspect it might be unburnt powder? The rifle was clean having only 11 rounds down the barrel after a clean, Ammo used federal smk 168 gr so clean burning by my experience with it, I’ve never seen this before so any input would be much appreciated thanks!
