Daniel Defence delta 5 pro 6.5 creedmoor issues.

[Frankjr]

I am having issues with my brass at shoulder and neck junction. I have about 400 plus rounds through this gun. I am using lapua and Peterson brass for reloads. Am I the only one that had a chamber that is forming brass like this? I don’t see brass lasting very long at this rate. If I’m doing something wrong please tell me.

Daniel defense is one of the best in the biz. If you call them and send them that upper i have 100% faith they will fix that

The middle (fired case), the shoulder angle looks different than new or resized.

take pics zoomed in on the neck/shoulder and email them to DD.

Zoomed in on the pictures.

You have a chamber that is not cut very well.

Something sure doesn't look right. Send it back to DD or get a local smith to do a chamber casting so you know what is going on.
