I suspect we will see a 25 Creedmoor or a 25 PRC of some sort (25-08 with 30 degree shoulder?) with a fast twist before long. The trend in shooting sports is certainly in that direction.
Yes, modern correctly designed cases with the right twist barrel and right throat and hopefully shooting .257 bullets with a good bc. It would be great. But you would still get some "Neanderthals" complaining that it is no better than their old....whatever.
