The Partitions are good bullets, but as has already been said, not needed for deer or pronghorn in standard weight loads. If you were to use a .224" bullet for deer or pronghorn, I'd say a premium bullet (Partition, Scirrocco, Barnes TSX) would make it a little better suited for deer, (but still very marginal in caliber). In anything .243 or larger in diameter, a CoreLokt, PowerPt, HotCor, or anything Hornady (except "varmint" bullets) is very capable of doing a good job for you. The premium bullets make a lot more sense on the bigger game with thicker skins or anything that would like to eat you for dinner.
Accuracy-wise, I have actually had better experience with the Barnes TSX than the Partition, plus you get better ballistics for any given weight. The Barnes can be a little finicky to get dialed in, but once you do, they can be real tack drivers going sub-MOA all day long.
One big key to bullet performance is to match the bullet to the task and keep the velocities within the design of that particular bullet. Drive it too fast, a bullet will explode before impact. Drive it too slow, it will not expand and penetration will be limited. Use a "varmint" bullet on big game and it will virtually explode upon impact and give you very little penetration.
