I wouldn't worry about the bullet too much, as with ALL bullets placement is the key.
I just got back from a hunt and bagged a moose and a large whitetail both with Sierra Matchkings, the critters had no idea that they weren't supposed to die when shot with a non-game bullet! Both were one shot kills, double lung...travel distance after being hit was in the area of 30 and 40 yards respectively. These were not shot at true long range distances the deer at 174 yards and the moose at 439.
