On elk I've used both the 150 NBT from a 270 Win, and 150 NBT from a 7-08. At 150 yards, the 270/150 whistled on through the lungs broadside on a good sized cow. At 40 yards, the 150 from the 7-08 angled through about 3' of bull elk, took out a lung, and was underneath the offside scapula.

I believe a 160 Partition would likely have penetrated the offside scapula and made it to the underside of the hide. But the result would have been no different.

This was a 7.5+ yo bull, which is a different animal than the average cow. 7mm/150 NBT:
