I have a real collection of bullets that I have dug out of game over the past 45+ years. Most of the recovered bullets are conventional cup/core bullets. I have a separate collection of Premiums I have recovered. [FWIW, I have recovered only 25% of the Nosler Partitions that I have shot game with, the others have been passthroughs.] It is no secret that I am a big Partition user, and have been for a long while. It is the bullet that I judge all other by. That being said, Jason makes a valid point as far as conventional bullets go. On smaller, non-dangerous game, they actually often kill as quickly (in some cases more quickly) than do the premiums. Placement is, of course very important. If you are going to take angled shots that may need to break heavy bone to reach vitals, then the premium has the edge. This is why I use Partitions. I know that if a Moose is standing quartering towards me, I can drive that partition through the shoulder bones and ribs into the heart lung area witout a doubt. A lighter constructed bullet may not breed such confidence. Just a short note on H4831's comment regarding that CIL Copper Point Expanding bullet: I had at least two of those pencil through deer with no evidence of any expansion at all. These animals required more shooting to put down. In all fairness, they may have worked well on bigger game like moose, but I did not get the chance to try them on moose. In my opinion (with no disrespect to H4831), they were never in the same class with the Partition. Regards, Eagleye.
