The bullet you are looking for is probably an X bullet (Barnes X if we are not being subtile), nevermind what some might say. The second best bullet is IMO a Swift A-Frame, but their after sales service sucks, to say the least. Partitions are not much better than std grade bullets, and should not be used on DG. Feel free to differ, but I bet I have seen more bullets in action than most. This of course does not make me the ultimate auhtority, just my opinion. Also, I have seen a lot of hunters to our continent "interpert" results different than I would have, but once again, I see at least 250 trophy big game animals die (and another 1000 plus culling animals) per year, so excuse me if I consider myself as an authority on the subject.
