Storing Powder and Primers

[BILLY D.]

when primers detonate they do so sympatetically. one goes, the next goes and so forth untill there are none left. store loosely, in other words not in a closed container because if they do detonate the closed container then is one big bomb.

powder will only explode if in a confined tight space ie :cartridge case. however as you have probably observed it burns very quickly.

and you are right, don't store together.
