I realize that nitrocellulose is a key component of smokeless powder. I am trying to wrap my head around just how / what the practical effect of this new "regulation" will be on us reloaders? Does it mean that any powder that has wetted nitrocellulose in it that exceeds 12.6% nitrogen is now subject to regulation as a "high explosive" (and I don't know if that is even possible in terms of the various chemical components used to make powder)? Or, does the new "regulation" apply strictly to nitrocellulose, and an exemption then applies once the nitrocellulose is combined with the other necessary chemical components that are used to make smokeless powder?

I don't want to be forced into a knee-jerk powder buying spree, (but I guess you can never really have too much in the way of powder or primers), but I don't to get blind-sided by Obongo and his Band of Bolsheviks either.
