He designed it to use up a box of carry ammo each year.
I have issues with someone shooting up their carry ammo because they think it may go bad. Most if not all factory ammo will out live the owner, as long as its not abused, and it takes some serious abuse to cause ammo to not function.
Yeah, but if its exposed to the elements (i.e. in your pistol while you're exposed to the elements), then there's a concern. Also, you should train with what you carry - especially when most CCW'ers are shooting +Ps in their J-frames and plinking with the wimpy stuff. In a lightweight especially, that's a much different recoil feeling.
