But, if the schitt ever hits the fan, or if there's another kink in reloading supplies.... it'll be much easier to make .260 brass out of the veritable cornucopia of .243/7-08/.308 brass in current circulation... than to make Creed or x47 brass.
I'm not sure even that is significant; Creed brass is easily formed from mil-spec 7.62 brass, if you're willing to give up a small amount of capacity, and from commerial .308 brass with one more step. I make my Creed brass from TW and LC, just a single pass through a standard Hornady 6.5 Creedmoor sizing die, no different than forming .260. With commercial brass though another step is needed; a shortened 7mm-08 die does the trick to bump the shoulder back without wrinkling.
