FWIW, she shot her last critter with her hubby's .300WSM. When she starts looking for a longer range hunting rifle, I'm not at all sure what to recommend. The availability and options for factory ammo will be far more important than any potential differences in accuracy - those differences are swamped by other factors including differences in rifle, trigger, barrel quality, chamber dimensions and so on.
The only thing I know for sure is it will be another lefty, which limits rifle options considerably. May end up with a semi-custom built from parts.
6.5 Creedmoor checks all those boxes...

Too late. Got her a 22" barreled lefty Rem M700 chambered for .270 Win. Loaded up some 150g LRAB to 2910fps. Recoil is mild, accuracy is great,
One of the goals I had for Daughter's rifle was the ability to deliver 2000fps and 1500fpe to 600 yards at 7000 feet altitude. The .270/150LRAG @ 2910fps meets these admittedly arbitrary goals out to 680 yards. The 6.5CM/140LRAB @ 2670fps (22" barrel) drops below 1500fpe @ 440 yards. At 600 yards the .270 has a calculated 13.7" less drop, an additional 180fps and 345fpe and an inch less drift. Granted, the 6.5CM will do it with about 70% of the recoil, but the .270 load is only 2 ft-lbs heavier than her .308 load - meaning it is easily in her comfort range.
