I just tossed one of my Federal 180 grain .40sw HiShoks, along with a random one of my 175 grain lead reloads into my toilet tank. The idea here is to see if they are waterproof. I'm going to leave them in there for a week or so and then see if any water got in. Anyone have any predictions? I'll update with what I find. Wanna kill these ads? We can help!
