So, clearly, ammo that is kept away from moisture can survive for decades with little ill effect. On a daily carry gun in humid Oklahoma, though, with constant exposure to sweat and the occasional elements, how frequently do you change out your personal protection ammo? The reason I ask is I had a veritable mag of squibs after 2 years of carrying it around. I was carrying Hornady TAP PD and there was so little energy left that they didn't cycle the action and sounded like a Hollywood silenced round. The stuff isn't cheap enough to justify rotating it into the shooting schedule every month, but then again the thought of carrying rounds that might literally bounce off who I was shooting them at scares the crap out of me. Just wondering what your personal experiences/thoughts were.
