There are many things you can do to protect your ammo from the elements. Keep it away from temperature fluctuations. Don’t let it sit in broad sunlight. But more than anything else, do not let it get anywhere near humidity. Moisture is the bane of ammo’s existence!

If you’re being smart and storing your ammo in a steel can or other sealed receptacle, then you’re on the precipice of making yet another smart decision. This is a 10-pack of silica desiccant packets. Each cotton pouch contains 5 grams of silica, and will passively absorb moisture from any air its surrounded by.

The 2-1/2" L x 1-1/4" W pouch is optimal for dehumidifying 648 cubic inches of contained air space. It’s no coincidence that that happens to be the same volume as the inside of a .50 cal M2A1 ammo can.

It’s safe practice to replace an ammo can’s silica packet each time you open it. And if you’re storing a pistol long term, then you can’t go wrong by sealing it up in a can with a silica packet!
