This just occurred to me as I was taking a look at my CZ52. I store the pistol in a shoe box sized wooden liquor box. In the box I have about 800 rounds of ammo. 200 rounds loose in the bottom and the rest in cardboard boxes. My question: Is this ammo corrosive to my pistol in this state by proximity? Or must it be fired in the gun to release the corrosive salts that damage the barrels? Basically is my ammo 'gassing' my pistol?
