Temp up here in Ole NoDak is colder than -20 lately. Say one has a powder order coming and that order sits on the delivery truck in the cold in transit and than sits out side in the cold (-20) for a few hours. Could this have negative effects one ones powder? I am guessing you would want to warm the powder back up slowly as to not produce too much condensation? It would be worrisome seeing frost one ones powder container. Maybe it's nothing To worry about since I have had frozen loaded cartridges in the same weather go bang just fine?! Something to discuss anyway
