I've been running Hornady brass since I started with the Creedmoor (5 years now) and haven't split one or had a separation yet (I anneal every firing though). The brass is from that time frame however. The main complaints on Hornady Creedmoor brass is the primer pockets. I really haven't lost too many from the primer pockets loosening either. Some have at least 7 reloads on them, and I run them pretty warm (2850 with 140 Hybrid's).
Maybe I misunderstood, but are you firing your reloads from multiple rifles with different chambers (6.5 Creedmoor of course)? The only time I do that is when I had chambers cut with the same reamer and then I still measure the brass carefully when that barrel is new (I suspect highly you already know that, just mentioning it).
I just haven't found Hornady brass to be as bad as some others. I have made Creedmoor brass from Lapua Palma brass and it is tough as it is reputed to be (but a large investment in time). This is just my experience as you are obviously having problems with the Hornady brass.
That's a negative on experience with Nosler brass. I also understand that Norma makes Creedmoor brass.

Yup...check that you are not bumping those shoulders back too much. I did that accidentally (0.005-0.007" shoulder bump) and was getting case head separation.
I made sure it is about 0.0015-0.002" bump and case head separation went away. I scrapped the brass that I knew I bumped the shoulders too much on. 80-100 pieces of brass scrapped.
I get a split neck here and there with hornady brass, but it is usually because it went through multiple firings without annealing.
Primer pockets, never had that much of an issue with them. I was getting about 8-12 firings on them.

Holy smokes. You practically made it into a new cartridge :-[ A Wilson case gage is wonderful tool for the loading bench. That gage and a dial caliper, with a set of Redding Competition Shellholders, are great tools for headspace control.
