One thing I would add is a 257 roberts is a nice cartridge but not a true short action where a 25 CREEDMOOR would likely be ideal for a short action quarter bore caliber so I could see that coming into existence and making a great hunting round for short actions. If any new 25 caliber cartridges come out I hope its that one. I don't hate the 6.5 Creedmoor by the way just all the bs usually associated with it.
