[QUOTE="Mikecr, post: 82149, member: 1521"] A bullet's sectional density goes up with weight. So if all else were kept equal, BC would go up with weight. Problem is, rarely is all else equal(shape length, etc) with more weight. To keep it equal specific gravity would need to change rather than dimensions. Use of Tungsten, etc. This is why a general statement that heavier bullets are higher in BC is incorrect. That may not be the case at all. Just compare pistal bullet BCs to lighter rifle bullet BCs for an example. [/QUOTE]
