All ammo and ammo related items are becoming extremely hard to find and when you do find them they are very expensive. They're going to get harder to find to, you just wait a little while and you will see.
Thankfully, caps are just like powder and not hard to make if you just follow a few simple rules.
Don't mean to launch off into a sermon here but I can tell ya'll right now that there are various groups and elements in this country that are bound and determined that any and all types of firearms will end up as nothing more than a club to smack someone over the head with. I knew when I got back from the 'Nam and found out about the 1968 Federal Gun Control Act that if I managed to live what is considered to be a full and normal life span that I would see this day.
There's one thing they may have not given any serious consideration to though. That's all these good ol' boys that will be in their basements, out in their barns, in the mountains, in the caves, just where ever they can find a place to set up shop, and the steel lathes and the wood lathes and the powder mills and the cap stamping machines will be running around the clock. "Man, I need some caps. I ain't got any money. You know how things are for everybody right now."
"Got anything to trade for some?"
" I got some cabbage, cucumbers, a few tomatoes and a little coffee. I need some caps to take care of my family."
" What you have is fine. We can trade. Come on in."
Well, why not? When I was borned in the back room at home in those Alabama hills so long ago, Daddy paid 9 ears of corn, 14 ripe tomatoes, 9 green tomatoes, and a mess of okra to the doctor. That was his bill, and I think I heard Daddy say one time that he also gave him 2 quarts of homebrew to sip on along the way..
