I am waiting for 6x47 Lapua brass. I simply prefer the x47L brass to the Creedmore option. I think its just being [bleep], but I like em. A fast twist 6x47 Lapua for the 105 AMax is in my future...
Sorry for the mostly irrelevant rambling...
But yes, I see the 6 Creedmore being legitimized in the future. It wouldn't do much more than a 243, except the nice shoulder angle. But it will be new and cool and will sell well as a commercial round.
