Should I bother sitting on bulk self defense rounds?

I've heard you want to cycle your ammo every year (or two? I forget) citing things like moisture causing potential reliability issues if stored for too long.Id want to obviously practice enough self defense rounds to establish reliability. However, I personally didn't notice too much of a difference between range ammo vs. my sig 9mm 124gr, so I don't see much of a point training often with the ammo for accuracy purposes. Is there a purpose of buying bulk if I'm going to have to fire it all off after a year or two? Or I've also heard to just store with desiccants? via /r/CCW https://ift.tt/JMRm6SP
