Not sure if you're joking or not, RemModel8. I first thought that might be a case of diminishing returns but I remember reading a few years ago on a 6.5x47 Lapua thread (different site) where someone first tried the 7x47 and the performance from that little cartridge was very impressive. So considering the difference in case capacity between the Lapua and the Creedmoor, the 8mm CM isn't a stretch.
