Do you know how old the bullets are? If they are over 10 years or so, I personally would not use them, nor would I use them if they are corroded. You can take them to a firing range or to a gun shop to dispose of them, some people may even buy them to reload. Usually bullets do not go bad, but depending on the age they may have gotten wet or lost some of their charge or they could have swelled causing a backfire.
Hope this helps.
