I used the 180 grain Nosler partitions, and they worked well. About half would exit, the other half would be found under the hide on the opposite side, usually weighing around 65%, give or take. Most of the front would be gone, the mushroomed rear is what penetrated.
I've since switched to the 200 grain partition and haven't recovered one yet. I like the partitions because the front portion almost always violently expands and seems to me causes more damage than accubonds or x bullets through the lungs, yet the rear still gives you the penetration. Nothing wrong with barnes x or accubonds Ive used them as well, I just prefer the 200 grain partitions for the reasons mentioned above.
