All I can say is, IMHO there is no good reason to wrap your lips around a barrel, other than to mimic Daniel Boone or Davey Crockett that you may have watched as a kid.It seems some folks just love to watch the smoke coming out of the nipple or vent.It really proves nothing,except to assure yourself by the smoke, that you have indeed shot the gun. I have not found blowing down the barrel, to soften fouling. To do so, I run a damp patch down the barrel to soften and remove the fouling. At the same time I can hear the "hiss" of a clear vent or nipple. I too, am wrapped up in the romance of muzzleloaders. But, blowing down my barrel is just more romantic than I need to be with my guns. :winking:
