The primers look a bit high, but they look a bit like a squib primer does. When the primer detonates it backs out of the pocket, and when the powder burns it shoves the case back against the breach face which reseats the primer. When that is done with extra violence it flattens the primer. When done with extreme excess pressure the primer cup will expand into any void it can, such as the firing pin hole and the chamfer around the primer pocket.
Your loads may be low enough pressure that it is not fully reseating the primers, and if that is the case then you don't have anything to worry about.
