China has cut off Nitrocellulose and Antimony to the U.S.

[Rudi]

I have 2 words for China, and can't use one of them here. The other is "OFF".

The nitrocellulose thing might not be all that big a deal-but the prices may not reflect that. A lot of the powders we use aren't produced here anyway.

At least for smokeless powder manufacture, production of NC is part of it. And virtually no civilian smokeless powder for civilian use is being made in the USA today.
