This has been fun to follow. Those cases should last forever.

I’ll be curious to know how much the cases grow and how much you’ll have to trim

Yeah that will be the real question. I’m thinking a guy is going to want to careful on setting the sizing die to just bump the shoulder to avoid it trying to slowly work the body out of the case head.

Was it just one pass through a .308 die to get the 6.8 sized to .308, or did you have to go in stages? I'm thinking these might be a good fit for my SFAR that's rough on case heads. I'd also be curious how hard it is and what's involved to form these to 6.5 Creed. I have a Sig Cross in 6.5 and I'm a little tempted to experiment with 6.5 Fury type loads.

Yes, just one pass through a 308 die. I didn’t aneal them either but that would certainly make it easier. I want to build up some confidence reloading them in a bolt before I try a semi auto. I suspect if you want to make them into 6.5C you’ll want to aneal them first and will probably have to turn the necks
