Bullet Frontal Area List

Compiled By Chuck Hawks


For an expanded list showing many more calibers see the "Expanded Rifle Bullet Frontal Area List" on the Tables, Charts and Lists Page.

Bullet frontal area is an important element in the killing power of rifle bullets. Other factors being equal, the bigger the diameter of the bullet, the bigger the diameter of the bullet hole.

What follows is a list of common rifle bullet diameters showing their frontal area (cross-sectional area), rounded off to four decimal places, in square inches. Under each bullet diameter are listed some of the common calibers using that bullet diameter. These frontal areas were collected from various sources (including the A-Square handloading manual Any Shot You Want) or computed by the simple formula: area = pi (3.1416) times the radius (1/2 the bullet diameter) squared.
