I can fit ten 30rnd AR mags into an ammo can. That took up 7 of my 50cal ammo cans! Geez, I have a lot. :) I usually have about 30 mags loaded and stored in my gun safe. It got tired of pulling them out one at a time to see what type of ammo I had loaded them up with. So I decided to color coded them.
RED = 223 Ballistic Tips (hunting).
YELLOW = 223 Full Metal Jacket (tactical drills).
GREEN = 223 hollowpoints (zombies)
BLUE = 223 Steel case crap (plinking).
WHITE&RED = 300 Blackout w/ ballistic tips.
WHITE&YELLOW = 300 Blackout w/ FMJ.
WHITE&GREEN = 300 Blackout (HP/subsonic)
The floorplate of the Magpul Pmags have 8 recessed areas and I filled in the colors. Most will have one color, as most will be 223/5.56. I don't expect to have much in 300 Blackout, since I was not planning on using Pmags for that caliber. Just GI mags.
All lined up and hanging off the cans, waiting for the paint to dry.
Previously, I did a write-up on color filling AR Receivers. I basically followed the same steps.
The rest of my ammo cans will store my reloaded ammo. Each can is labeled with caliber and load data. I have 4 cans that are also filled with factory ammo. All will be stored away for safe keeping, or until the need arises.
