It's the most potent combination you can have in a compact AR15, with expansion out at distance for hunting, low recoil, and ease of maneuver.
10.5" gives you expansion out to 260yds with the 123gr SST, and 700yds with the 129gr ABLR, which is more than twice the distance you would engage medium game at in most cases.
The 10.5" 6.5 Grendel with 129gr ABLR maintains 900ft-lbs of energy out to just over 275yds, and 800ft-lbs to almost 375yds if you care about ft-lbs.
11.5" with a 129gr ABLR gives you:
100yds 2066fps 1223ft-lbs
200yds 1928fps 1065ft-lbs
300yds 1796fps 924ft-lbs
400yds 1671fps 800ft-lbs
12.5" 129gr ABLR
425yds 1674fps 802ft-lbs
123gr SST at 2320fps mv
300yds 1816fps 900ft-lbs
375yds 1702fps 791ft-lbs
Just for reference using a 20" barreled .30-30 with a 150gr RN Hornady:
175yds 1599fps 852ft-lbs
200yds 1515fps 764ft-lbs
