I started collecting firearms as an investment but I soon realized that that my ammo collection was worth quite a bit as well, especially as brass has shot up. For example, I got a deal on some 5.56 nato rounds that are worth 4 times what I paid for them, that's almost a 150% compounding annual return; better than any gun that I have ever purchased. My ammo has it's own safe.
