Changed homes after 30 years and my area reserved for reloading is about 50% smaller. I was thinking about storing my reloading powders in one of those storage cabinets made out of plastic with a lock to keep the grandkids out. Planned to put it in the panic room due to lack of flammable materials but wonder if in case of a fire there would be less chance of any kind of explosion if it was stored out in open storage racks. I have a good deal of powder but its all stored in the original containers, plastic, paper, metal, ect. Figured to store the primers in a seperate location also under lock. Might be better off trying to find a fireproof door for the panic room and then it might not make much difference how its stored. Just wondering what some of you other shooters thought. Thanks for any input.
