Hornady LRP Creedmoore Brass question. These cases are different.

So, I had a batch of Hornady range brass and upon inspecting the inner case and flash hole I noticed that there was a pretty even ratio of cases that had this "indented" portion on the inside of the case around the flash hole. I'll let the photos describe it. I have tried Google but I figured I'd have better luck here. Could it possibly be due to being loaded too hot? The indents seem pretty uniform between them.

Reloading them I am separating the two groups but was curious as to how common this is. Maybe I'll h20 capacity test them tomorrow
Thanks in advance for any replies

That's likely just a result from the bunting process (after the brass cup is drawn, and when the headstamp is done) when the case was formed. I'd guess that it is probably two different lots of brass.
 
Right on, looks like those are the points in the process where it would definitely show up. It caught me by surprise, thank you all for the info. I appreciate the prompt responses. I'll sort them and load accordingly. Cheers!
 
The indented ones are from older lots. They are lighter in weigh and have more capacity.
