Can someone please point me in the right direction of a link or thread that outlines how you break down ammo/weapons and what it takes to make new ones. I love this aspect of the game but haven't really been able to figure out exactly how it works yet. The only thing I think I understand is that the cases are for making new ammunition.

If you look on the lower right it will tell you what and how many componants you need and how many you have. same for the work bench.
