Well, I'm going to disagree with several of you. I believe the way the bullet is constructed like concentricity, jacket thickness, uniform weights & uniform diameters have much more to do with accuracy than the particular shape of the bullet. I can think of several instances in my reloading where round nosed bullets beat the pointy ones in the accuracy department by a good margin.
Sierra and Berger bullets have a great reputation for accuracy and yes, they're boat tailed hollow points but their construction is also very precise.
At ranges over say 200 yards, the boat tailed design has some advantages because it doesn't slow down as fast as a flat based design so will tend to be more stable. Also, there is the belief that when the bullet goes from supersonic to subsonic, the boat tailed design will remain more stable.
