I thought about using an Ablr in my 20" howa for an elk hunt (Colo) couple of years ago... but honestly for 200-250 and under you'd be well-served by staying with the 123 class. I was using CFE223 and got about 2460 ft/s out of the 20" bolt gun for the Ablr (never took a shot on that hunt however... bummer!)...
But CFE does have some real temp variability.
In the 123 class you can look at AR Comp and 8208xbr (as mentioned this one can get quick-appearing pressure spikes so be careful), 123 sst, 120 gold dot, maybe couple of others... should be gtg out to 250 at your altitudes.
1Shot gets 2550 MV for his gold dots in TN. Other 123 class should be 2480-2525 or so MV.
Another one to think about is the 100 gr ttsx from Barnes, you'd be looking at an MV of ~2700 from a 20" and range out to 250-275 yds, still with enough V for mushrooming.
I know there are better shooters on here but I'd limit myself to this range with my Grrrs, for longer I might use my 6.5 CM or even my 6mmCM.
