Handling blackpowder is handling black powder - a pound in a can is a pound in a can - no more dangerous pouring a pound of meal out of the mill drum than decanting from a pound can IN THE LOADING ROOM INTO YOUR POWDER MEASURE - proly LESS dangerous because I bet the homemaker is way more cautious around his powder that most shooters with boughten powder are. Bulk quantities make black powder more dangerous and stupidity seals the deal.
