I guess I'm a hoarder, sorta kinda. Over the decades as I bought brick upon bricks of .22 target ammo to shoot I would typically fire 1/2 -2/3 of them and put the remainder on the shelf. Repeated enough times over 30-40 years and the "remaindered" pile grew and grew. Without consciously trying to I guess that made me a hoarder as I've weathered every dry spell handily. Pretty much ditto with all sizes of primers too. I guess laziness and forgetfulness has its strong points.
