[QUOTE="dennishoddy, post: 2566439, member: 5412"] The ballistics coefficient determines how the bullet will fly down range. A chronograph will determine the bullets speed, and you can develop your dope from that data. Factory's publish guidelines but there are lots of variables in long range shooting beyond what they say. Barrel length, humidity, barometric pressure, etc all have an effect. At short ranges like 100-300 yards, there is not much effect by the atmospheric variables. Out to 600 to a grand, the game changes. [/QUOTE]
