Ammunition Storage - Re-usable Indicating Silica Gel Canisters

Ammunition needs to be kept dry.  Sealed containers are start.  Adding silica gel packs to absorb any extra moisture inside is even better.

When I first started my stockpile collection, I dropped 10g packets into each ammo can.  As I'm rotating through the hoard sensible supply, I'm finding that the packets are now indicating 60% saturated.  I've decided to add date labels with a piece of painters tape to reduce my opening and closing. (They are already labeled by caliber.)

SilicaGelPackets.com has a nice selection of non-carcinogenic indicating gel packets. The 10g packets that are perfect for a .50cal ammo can~(approx 1200 in^3), are packaged in plastic baggies that will melt in the oven when trying to dry 'em out.  They also sell the stuff in bulk.

I have some cigar tins lying around that are perfect for the gun cabinet, but a little bulky for the ammo cans. So enter the google-fu and I found some aluminum lip-balm containers on bulkapothecary.com that look to be the right size. A little tinsmithing with a finish nail on the tops, and voila==> small re-usable, indicating silica gel canisters.

3 hours @ 300F when the orange turns green and you're good to go.

For a relatively small investment <$50,  I have 50 packets that can be reused.  (I'm also reclaiming the beads from all the plastic baggies to re-use in the cigar tins.)

So...how do you keep your powder dry?

And do you practice any specific inventory management scheme when heading to the range or storing new purchases?  FIFO, LIFO, WIHOH.

(FIFO = First In, First Out)
(LIFO = Last In, First Out)
