This happened 4 years ago and it took almost 2 years to settle back down to normal. That said, I have been able to get most of what I need by posting here in the classifieds and watching online and had a descent stockpile to start with. If you keep an eye on all the online suppliers you can usually find some components here and there. Yup, It's a PITA, but it's where we are ATM.
The lesson to learn, is to keep at least a year, maybe 2, of supplies on hand. If everyone did this there would be less hoarding every time events like this happened. That's what I'll be doing.
Of course it doesn't help much when you buy a new rifle and don't have the powder, brass and bullets for it.
Oh well, venting might help a little, but it is what it is. As I learned in the Scouts, "Be Prepared"
