Looks altered. It wasn't struck that way.

It appears very consistent to be PMD, and would be the first time I've seen damage like that. I though that the collar may have been involved somehow, but I don't exactly know how. There are no scratches, gouges and it appears almost like you would expect a struck-through grease error to look, except very straight and on the edge.  In Memory of Crazyb0 12-26-1951 to 7-27-2020

Keen observation on your part. I never would have noticed that.

It SHOULD, but it doesn't always. Especially when they get in a hurry and speed up the equipment or don't have milling pressure set high enough.
