The ejection pattern is on the verge of under gassed. The dents in your brass are likely from an overly long ejector spring. There are a few threads here explaining how to trim that to tune it for Grendel.
Thinking more about it now. BA sizes their gas ports on the small side for folks that run suppressors. I have read that in several threads. I will tune that spring and see how she runs.
