I don't know what all you gun nuts are so scared for to think you need to own all of this ammunition. I keep 1 round for my one gun that I own, and I keep it in my pocket at all times for safe keeping.
To answer the OP, I think that it all depends on what you are storing it for, and how often and how much you shoot rifle as opposed to pistol.
