Klik,
I wouldn't leap to any vast conclusions about the 150 Partition because of that deer. I have seen a 210 .338 stopped by a whitetail buck on a quartering shot, and it wasn't all the big a buck, no more than 150 pounds field-dressed. The cartridge was the .338 Winchester Magnum and the range was less than 200 yards.
There is something about an angling shot that tends to stop bullets, especially when they break out of the flesh at an angle to underside the of the hide. Many of the Barnes X's I've recovered, for instance, are found after such shots.
Though I do tend to agree that the 150 .30 Partition is a little stubby for bigger game. I would have no qualms about using any of the Partitions from 165 on up, though....
