Re: Need some advise
the aluminum cases will be dull silver and the nickel plated reloadable cases will be bright, almost mirror finished. Once they're fired, you can easily tell, if it's alum, you can crush it easily under toe. My guess is that with the headstamps you've listed, they're probably nickel plated. Also, you won't find too many manufacturers that load any alum cased .38's. make sure you check to see if any are 38+P, if they are, ensure your firearm is rated to fire them.
