2 things - 1st they generaly aren't using a 129 grn to shoot 1000 yds. The bullet of choice for the 1000 yd shooters with a 6.5mm is anywhere from 140 to 150+ grns. 2nd, those super-long 6.5mm bullets have the highest BC of any bullet generally available. So, when you compare a .308 to .260 you have the same powder capacity shooting a much higher BC bullet. That equates to a lot of retained speed at long distances.
