Hey guys, I keep hearing about these magazines for storing smokeless gun powder. Any of you ever build one? I've read the best thing to do is make a 1" thick wood box for storage...
Any input here would be helpful, thanks.

Yup. Built one for powder and one for primers. There are lots of ways to do it, but the cheapest and easiest way to do it is with 2x6 or 2x8 lumber. Use 2x2s inside to keep all together and a small piece of plywood to hold the top pieces together.

I just bought a cabinet 24x60x24 which is divided into three separate compartments, each with its own door,  It's 3/4 laminated press board, and each compartment has an adjustable shelf.  

It keeps the powder cool, dry, in the dark, and away from any other outside sources. It's not air tight so air can move around the plastic canisters.  Powder is kept in the left compartment, bullets and empty boxes in the middle, and primers in the right.  
 

Hmmm I have 3 pallets that I was going to use for the firepit, but now it looks like I'm building a powder magazine.

Thank you for the info. and pictures. I will work on making that this weekend.
