I know this is a real old thread, but I'm new to the forum and I recently found several hundred rounds of Zero Unconditionally Guaranteed .38 special 148 gr wadcutters. I think theses bullets could be from the late 70's or early 80's and was wondering if they are still safe to fire. I also have several boxes of 3-D Co. inc .38 special Police Cartridges, Western .38 sp. 158 gr. and winchester .32 Auto 71 gr. F.M.C..
One of the boxes had what appeared to be a date code of 18 20KK82 thats why I gave the date range.
Any info or input would be appreciated.

Thanks
Paul
