What is the definition of “burn rate”?

Burn rate is the speed at which a powder consumes itself, generating gas to propel a bullet. The faster the burn rate, the less powder required to reach a specific pressure, also less gas is created to push the projectile. There are approximately 170 different powders available to reloaders. Depending on the cartridge case capacity, bullet weight and barrel length only a few powders will give optimum performance. Too fast a powder will yield low velocities and too slow a powder will not reach maximum pressures or velocities.
