Expanded Rifle Bullet Sectional Density List

Compiled By Chuck Hawks


Sectional density (SD) is defined as the weight of a bullet (in pounds) divided by the square of its diameter (in inches). You can use that formula to compute the SD of any bullet not listed below.

The following list is a complete as I can make it and includes all of the popular bullet weights used in all common (and may uncommon) rifle calibers. It is the most comprehensive list of rifle bullet sectional densities of which I am aware.
