A friend of mine was kind enough to give me a couple hundred rounds of reloaded 9mm. However i supose the ammo was in contact with some moisture during years of storage. Some rounds were discolored and some had spots of corrosion. I went through every one with a wire brush, steel wool, and/or a rag. The exterior cleaned up pretty nicely. My question is: Should i be worried about any internal damage from around the primer or end of the shell? There were some that were really corroded that he didn't even give me and a few that actually had cracked shells. I just wanted to be sure before i take them to the range. If there are some "clicks", i can live with that but i don't want anything catastrophic. Any advice or experience would be appreciated.
