[QUOTE="Fiftydriver, post: 155464, member: 10"] Ballistic Coefficent is determined by the amount of velocity lose that a projectile has as it travels down range. Velocity drop also determines the effect of gravity on the bullet down range and also the effect the wind will have on a bullet down range. To greatly simplify things, the faster a bullet velocity drops, the more the bulllet will drop due to gravity and the more the wind will push the bullet off course. BC is just a number we can use to get an idea of how a bullet will perform ballistically and also helps us compare it to other bullet designs. Kirby Allen(50) [/QUOTE]
