Barnes Vortex 110 gr is as good as it gets for the .300 BO. Sure there are others that work but the caliber was designed around this bullet and velocity for supers and then the 220gr for subs.
My son killed 2 does last year with factory loaded Barnes. 16" bolt action. Both broadside lung shots. One ran 80ish yards, the other maybe 30. Both exited and left good blood trails. I tried to get him to crunch shoulders but oh well.
