I've resized about 400 of these cases to 6.5 Creedmoor.

A few things to note:
1. These are factory pulldowns (at American Reloading) for a reason. I've bought four different batches and seen huge lots to lot swings in case weight and velocity with the same charges. So buy all that you'll want at once so you don't end up weight sorting like me. On a good sale they are $0.40 each or less.
2. Resizing to 308 then 6.5 CM worked best for me, but I needed to anneal in between or it wouldn't completely size before work hardening too much.
3. For my Tikka CTR chamber and Hornady case gauge, I need to neck turn to chamber 6.5 Creed. The case body brass ends up much thicker than it should be at the neck. This was a massive pain.
4. After firing these cases are not hot at all, I think the steel has so much more heat capacity it has that effect. Annealing is also a bit tougher to do that usual for the same reason, hotter and shorter is best.
5. Overuse the case lube (and annealing) when sizing. Stuck cases are damned near impossible to remove the usual way, the steel bases will pop off. I ended up getting a very oversized tap and screw as below to grip on the brass body.

6. For the same reason, I'm concerned about case life and case head separation. There are basically no pressure signs short of primer flow and sticky bolts, at which point you're probably way way over 80ksi. And short of the couple of times I was resizing and got the steel base to spin separately from brass, I'm not sure how you would tell if you're getting case stretch at the 0.2" line and at risk for separation.
7. I'm enjoying tinkering with these cases and I think are well suited for low volume hunting applications rather than the match gun I'm trying to use them for.
