Ballistics Coefficient

Ballistics Coefficient is the ratio of a bullets Sectional Density to its coefficient of form.

Coefficient of form is a number which describes a bullets shape.

Ballistics Coefficient is important because, all other variables being equal, a bullet with a higher Ballistics Coefficient will:

  • Lose less energy and speed in flight
  • Drop less on the way to the target
  • Penetrate more effectively into a target

Ballistics Coefficient is abbreviated BC.

Books on Ballistics and Ammunition

Stopping Power: A Practical Analysis of the Latest Handgun Ammunition
Stopping Power: A Practical Analysis of the Latest Handgun Ammunition

Evan Marshall and Ed Sanow rocked the firearms world with the release of HandgunStopping Power and Street Stoppers. Both books predicted the effectiveness of all types of ammunition by studying the results of real-life shootings rather than relying on laboratory tests that ignored the dynamics of an actual gunfight. This third book in the series provides the very latest street results of all the major handgun calibers, from .22 LR to .45 ACP, as well as popular rifle and shotgun loads. It also contains chapters on short-barrel ballistics, the emergence of the hot new .357 SIG caliber, the continued success of the .40 S&W, the development of the latest exotic ammo, the effectiveness of black powder firearms and a brand-new ammo test protocol based on the results of the many gunfights of U.S. Border Patrol officers.
