No offense but the "I personally have not done it" comment above is not helping with this topic. The OP was asking for real world feedback. I have shot a mile and beyond and it was certainly not with a .308. It's all done at 1,000 and 1,250 is a stretch. Yes, people have done it, however, its far and few between and in ideal conditions. Those that shoot ELR choose a far better BC/caliber. I have many .308's and love them. I just know their limitations.
