[QUOTE="edge, post: 200673, member: 5030"] IMO, you have a lot of different issues here. BC, in short is based on the shape and the SD of the bullet. Make a normal bullet out of aluminum and the BC goes down, make it out of tungsten and it goes up. Most rifles have a twist for normal bullets. If you plan on making an extra long bullet then the rifle maker would need to make it with a tighter twist. The Drag is not just one item, it is Nose drag ( which is the largest drag ), then there is Base drag and Skin drag. I think that most target bullets are hollow points because it is the easiest shape to make consistently accurate. edge. [/QUOTE]
