For twenty years I used 150 grain cup & core 30-06 bullets and killed a bunch of elk. But one day it took three shots in the chest at close range to drop a cow elk. She just stood there while I pumped rounds into her lungs. She was so close that I could see the hair raise and the muscles twitch each time a bullet hit her. That's not the kind of performance that I wanted so I switched to 30-06, 180 grain Nosler Partitions. That was twenty years ago and there have been no problems with that bullet.

I've had that happen, too. I'm betting that on the 1st shot, she went into shock. When the blood pressure drops fast, the NCS pretty much freezes up and they just stand there oblivious to everything until the rest of the system fails. It's not the size or type of bullet. It's where it hits that does it. It's a sure killer but it fools you. It would take a trauma team to keep one alive at that point.
