Safety is such a lovely topic.
It is amazing that we all agree we support the goals, but we can almost come to blows over what those goals are. I would like to offer that we break the topic of safety into separate issues. Ram the first volley or not. Loading from the horn - I think some folks think this means pouring powder directly from a horn into the muzzle like in some old Fess Parker movies from the 1950's. Anyway, if you are pouring from a horn into a measure, THEN from the measure to the muzzle, I don't see a problem.
