In an ordinary ballistics examination of a .45 slug found in a freshly killed body, sufficiently intact to determine its caliber and get whatever other info they get, could it be identified as being thirty to forty years old, manufactured in the 70s or earlier? And, that it was fired by a military weapon of forty to fifty years since manufacture. I.e., both were military and old. Would a ballistics expert take notice of whatever indications there might be to establish that information about the slug?
Thanks to whomever can help me.
