I do it because I am NOT going to have a cook off because of an ember. The vast majority of BP shooters did it for years and in history and then, the aunt Mary's decided it was wrong. No thank you, I don't need it cooking off in my face -- for which you people will also try and blame on me. No thank you. Keep your participation trophys and all that. More modern leftist bs.I do believe that a lot of the guys that blow down the muzzle do it partly for the shock value to bystanders, though.
