what in real world benefits do you really expect this new cartridge to do better under field conditions hunting game?
than what good rifle chambered in a 257 wby, 7mm stw or 300 wby, 340 wby, could provide used in experience skilled hands?
I can't see any advantages, unless, your extremely recoil sensitive ,and just want to spend cash on new toys, look if the object, of using the new cartridge is to place a good deal of energy on target down range at over 400 yards I don,t see where an inch or so flatter trajectory is going to change the outcome under field conditions on most hunts with the new caliber vs several of the older established cartridges
