FWIW, I went to CO and dropped a nice Mulie with a 270 and 52.0/IMR4350 under a 150 Partition. Seems that was max in that 700, 24" bbl. Range 275 yds, stopped just short of exiting the ham/hide after punched just to the side of the throat, head on.

Chrono'd 2850 mv - it was enough.......

Whatever you use, KNOW the POI/POA, and use a proper bullet.

No animal will know the difference.....

That said, in the 6.5s, alot of folks use "H" and it's reported to give about 75 more fps.
