XC brass from Creedmore brass

Has anyone done this?? Considering using Lapua brass for this.
I suspect the problem, if there is one, would come from pushing
the shoulder back.

I've made plenty of 6.5 Creedmoor brass from Lapua Palma cases and much of the new neck is 'old shoulder'. It took initial turning, firing, final turning before they settled in but it made outstanding cases. About 5/100 would not resize correctly so they were scrapped. I would think making XC from Creedmoor brass would push the shoulder back less than .308 to Creedmoor.

I may give it a try w/ some Alpha brass, which I think may be a bit better stuff than Lapua.
