Correct...I store reloaded ammo in a safe. I store my powder in the garage on the top shelf out of reach (need a ladder to get to it)...this is the same for my primers.
I can see the other point of view that powder in a sealed metal safe would create a large amount of pressure...as an example, if powder is burned on a concrete floor, it just fizzles however if ignited in a sealed container such as a brass case, it would create pressure (I believe this is how loaded ammunition works)....GOOD POINT!
I like the wooden box idea (or a lockable plastic one)...maybe I'll consider this as another winter project and build one with a locking system.
So from the sounds of it, reloaded ammo and powder can last for a very long time so long as it is stored properly (cool and dry place).
Thanks for the input everyone.
IIRC, as per Explosives Act, you have to store powder in a wooden box with brass fittings and store primers separately.
I remember the look I got from a Home Depot guy when I told him I needed to get some boards cut to make a box for explosives.. he turned out to have a friend who reloads too and awkward moment turned into smiles
