ive got a special place for storing my ammo supply . its starting to get full to the top. i figure if i take all the ammo out of the boxes they come in and put them into the big clear ziplock bags i could fit alot more. will this be ok? id prob drop a few moisture repellant tabs in each bag and not fully zip each bag shut? will it be ok or will the plastic cause rust and problems? its not exposed to any light either.
