I wouldn't be to concerned with those choices they will all work and your only talking 300 yards.
I used a 129gr nosler long range Accubond from my 260 on elk last season with no issue.
Lots of elk are killed with both the .260 Rem and 6.5 Creedmoor and the 130 class bullets. There is plenty of energy available at 300 yards. Elk are not bullet-proof. Your responsibility is still to make the best, killing shot.
I've used the .240 Weatherby cartridge to kill deer and a couple of elk. The right bullet, right shot placement and yardage justified by energy constraints. One shot, down and in the freezer.
My 6.5 Creedmoor bullet is either the 130 grain Golden Target Match or the Scirocco 2.
