My opinion/experience on split necks is that they are mostly caused by tooling marks on expander balls and/or use of Imperial Sizing Wax too thick.
I've had one split neck with Lapua brass when I was using Imperial Wax on a roller pad. I think I was pushing my necks around way too much.
I switched to Hornady One-Shot spray-on lube and haven't had an issue since, and that was many years ago.
