I have often wondered about this. Let's say we come home after a hurricane and I wear my gun for days. No power,no A/C. So my gun and ammo are constantly drenched with sweat. What to do? Does it matter as far as the ammo? Will it function? I know people have carried guns and ammo in wars for 200 years or so. Any opinions or technical advice? I am not the type to coddle or baby a gun, but I do believe in basic common sense care. Does moisture of this type cause ammo to malfunction? In the days after hurricane Ike my cell phone became so drenched it was ruined.That is what started this thought about guns and sweat.
