I am looking to have four investments
silver
btc
fed bonds
real estate.

If ammunition becomes a truly important investment, it will be taken away from the less experienced by the more experienced and trained. You can rely on bunkers and machine guns in the barn either if you have your own mini-army, or while the majority of those around you are law-abiding.
I prefer to hope that I will not have to find out in practice whether my thoughts about the prospects of investing in ammunition are correct, so I choose Bitcoin.
this is a quite good post.
I have a few shotguns and some rounds. I rather not have to buy a lot of them.
