Finally moving into a house with a basement which means I can set up a proper reloading area. One of my major concerns, however, is proper storage of powder. People seem to suggest a 1" thick wooden box for amounts exceeding 20 pounds but not more than 50 pounds (which is probably the range I'll be in). Is this a suitable recommendation? Are there any local (in the triangle) places I should look to buy such a box? Are fire safety cabinets (such as these) overkill? Thanks!
