The powder is safe to store in the containers which you buy them in, and I just keep them stored in a dry location away from direct light and heat. If you set up a reloading desk out of an old teachers desk, you can use one drawer to store powder and another to store your dies and other reloading tools. Buying a reloading manual such as the Speer or Lee or any other mainstream outlet will help you to better understand how to get set up for a lifetime of reloading.
