My apartment flooded about a year and a half ago and a bunch of my .22 ammo got wet. I dried it all out right away but the moisture has affected the wax coating on the bullets. I've shot some of it and never had one fail to go bang, but the wax is white now and seems to flake off easily, leaving wax dust on the bottom of the container they are stored in. I tried a search and came up empty, but I thought I remember reading something about not using .22 ammo that has gotten wet/had the wax get messed up. Is this true, and if so, why?
