HITS calculator

The "Hornady Index of Terminal Standards" calculator is a resource designed to help hunters choose effective bullet/cartridge combinations for any hunting situation in the world.

Traditional muzzle energy figures do not take into account for the manner in which energy is transferred from the bullet to game animals. HITS factors in Bullet Weight, Sectional Density, Ballistics Coefficient, and Impact Velocity and delivers a rating that will fall into one of the four classifications below. Bullet construction is also a very important factor to consider. If you have questions as to which Hornady bullet is right for you, there is a quick performance reference listed at the bottom of the page.

The H.I.T.S. rating on Hornady ammunition is based on: 100 yard impact velocities for rifles, muzzleloaders, and shotguns and 50 yard impact velocities for handguns.

Bullet Weight (grains)

must be between 10 grains and 800 grains

Bullet Diameter (inches)

must be between .100" and 1.000"
(to the nearest thousandth, .224" or .308" etc.)

or select

Impact Velocity (fps)

must be between 100 and 4400 fps
