Quote taken from my latest 6x47 Lapua thread:
These first two times out I was using the 6.5x47 brass necked down & turned, with Rem 7 1/2 primers. Since I had shot Hunter Benchrest for a bunch of years, I had quite a few 30x47 brass that had been shot a zillion times laying around. These were originally made from 308 Lapua brass, with the shoulder pushed back, extra neck length cut off, necked down, inside reamed, and outside neck turned for competition. So I necked them down again, and turned the necks to fit, and on to testing the difference between small 7 1/2 primers & large rifle Federal 210 primered brass.
