Believe it or not, I've had one cup-and-core 150-grain roundnose factory bullet come apart on a doe whitetail's shoulder and fail to penetrate the chest cavity. Ever since I've used 170-grain Nosler Partitions, and they tend to put deer down pretty darn quickly, while always penetrating. This is because the front core of Partitions is a very soft lead alloy, and when combined with the round-nose it really opens nicely.
The same bullet really puts the hurt on woods deer when loaded in the .300 Savage.
JB, that brings up a question.....if a particular bullet fails to perform as expected once, do you ever trust it again? Several people have said my experience may have just been a fluke. I thought that may have been the case too but it doesn't inspire confidence! Lack of penetration wasn't my problem. You wouldn't care to identify that bullet would you?
