Oof my guy stop believing Facebook posts like a boomer. Turan doesn't even make .30_06 ammunition.
Also, bullets are typically "engraved" along the side of the casing, not the back, where they are stamped by the manufacturer.
Here is an example of an engraved .30_06 round. I'm sure the shooters round is much less well done, but this example shows the kind of detail that can be achieved.
