Probably depends somewhat on the quality of the barrel, but ~5k+ seems like a reasonable expectation for the top-quality barrels to maintain respectable accuracy, especially if used primarily for deliberate shooting without heating things up with mag dumps.
Generally speaking, I don't think the 6.5 bore at Grendel velocities is terribly hard on barrels. Shrink the bore and increase the speed, such as the case with some of the 6mm Grendel-based wildcats, and life expectancy will likely decline.
