I used the 165g Accubond (Nosler Factory loading 30-06 @ 2800 fps) on my elk this year. Terminal performance is supposed to be very similar to the 165 Partition. Quartering towards, hit just ahead of shoulder and exited behind offside shoulder. Took out both lungs and the area above the heart with all the arteries for a DRT one shot kill. Distance was less than 50 yds.
