Partitions are never a poor choice regardless of the application.

Nosler makes three great 140 grain .284" diameter bullets, the AccuBond (AB), Ballistic Tip (BT), and Partition. If either you or he feel the need for more speed, the 120 grain BT has a good reputation and you could probably get another 200+/- fps, if 200+/- additional fps would make a meaningful difference.
