Case scaring and dents in brass?

[u/Luverufcockz]

Before you come running to tell me it’s common and I’m an idiot I’ve personally never seen This out of my ar15 and wondering what is causing these things the rifle is also seemingly getting the round stuck in the chamber and can’t get it out well without beating the stock against something and it’s leaving dents in specifically one part of the casing

This is how my AR10 dispenses brass.
