I was reading a V-V Reloading Guide and they state: "Do not store primers in bulk. Doing so will create a bomb! Bulk primers will very likely mass detonate. The blast of a few hundred primers corresponds to a hand grenade in a room"! I have thousands stored in my office furniture most of which are in the cardboard as shipped. I keep the powder in the same room but inside a closet. What is the safe way?
