Thread: Brass issue?

There's about 7 out of 60 that look like this. This was the worst of thhe lot. I thought case head seperation occured a bit further up? I bought the rifle new and it's fired around 50rnds.

Edit* Just went back to the press and wound the die in a further 3/4 turn, on some brass it has removed the bump others have been reduced but belt is still visible. However in the process of doing this could I potentially be bumping the shoulder back to far?
