WWII ammunition, which was stored in warehouses that burned in the summer and froze in the winter, is still working fine.
The truth is that there is probably a 99.9999999999999% chance your carry ammo is good unless it is turning green or the bullet has been pushed back in the case (set back).
If it makes you feel better to replace it, then by all means do so.
Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passions, they cannot alter the state of facts and evidence. - John Adams
At least every other License renewal I try to remember to drop them in a bowl of C.L.R. or Lime-Away ( ) and use emery cloth or wet/dry sandpaper to remove that green corrosion buildup. In other words, every time I clean my Glock.
(No, really swap out the "carry" Critical Defense yearly ... I think)
Thanks for the reminder.
