What I have found with Lapua as you (I) use it, the neck tension gets less.
If I anneal it, then it gets tighter for a bit.
Either way its consistent, just different tensions. No idea why.
Other brass acts differently. Lapua is the only case I have to the 6.5 (Pederson is the only other supplier and it costs more).
Flip side is at least in a good chamber on a custom barrel, Lapua last 10+ cycles before anneal and even then I have yet to crack a case, not sure how many cycles it would go.
I just accept what I find and deal with it accordingly. Someone might have an answer but trying to separate real answers out of opinions? Shrug.
