I to am not saying Lapua brass is bad, just that their are documented cases of the problem.
That thread may be the one that shows the sectioned cases. But this issue has been known for a little while in the Grendel crowd and the ARC is a cousin to it so they exhibit similar problems, and you can math down the Grendel load data from it to get a starting load point. I have done this because in the beginning there was only the load data supplied by Hornady..
The only other thing that I can think of you are experiencing early extraction.
Yours is not an isolated occurrence.
I found a couple of pictures for you. The first one is Lapua Grendel brass, the second is just to show you how much difference different brands of brass exhibit. And these are Grendel as well.

If you can not see the tyranny of having a gun ban enforced by men with guns... Then you fail to understand why the second amendment was written in the first place.
