I have been picking up range brass for more years than I can count. I have only had 2 or 3 problems in thousands of rounds. Before you clean it take a look. Look for signs of pressure or having been reloaded several times. If you see signs like that throw it away. Also when your priming it, if the primer pocket has been enlarged get rid of that brass also. If there is any question in your mind that the brass is no good don't reload it. However it cuts reloading costs.
Just my 2 cents worth
