Sectional Density - The relationship between a bullet's weight and its diameter. For a given amount of energy, a long bullet, such as the original loading for the Mannlicher Schoenauer Model 1903, the 6.5x54mm, top above, will have a high sectional density and consequently greater penetration than a shorter bullet of similar construction. The shorter bullet with less sectional density, such as that in the .45ACP, bottom above, will have relatively less penetration, but greater knockdown power.
