We are sorry for the error in sizing and this will be corrected so any future orders will be sized correctly. Please accept our $20.00 credit to your account for you to return the wrong sized bullets. We will resize them here and ship you correctly sized bullets back at no charge. We are sorry for the error the company sent us the new .356 die had it mis-marked and we didn't realize the mistake. Thank you for letting us know and we will take care of getting you the correct size so you don't have to resize them yourself.
