We should also include knives and fertilizer plants.

I predict a federal background check and quantity limits on black powder are a done deal. Who knows about pressure cookers. It may make it tough for those of us who can at home. Banning pressure cookers is just absurd enough that someone will try to do it.

There's already quite a process involved in buying black powder and unfortunately for those of us who shoot tradional style Muzzleloaders, nothing else works. I need to order a couple of cans now although I'm wondering if its already too late and black powder will become the next ammunition thing.

I've seen recipes for it. I know it's sulfur, saltpeter, and charcoal. I've read that the process for making the charcoal was a state secret in 16-17th century Europe. But you're right, I think they used willow. I mold my own bullets. Maybe I'll have to go total 18th century and make powder too.
