[QUOTE="AJ Peacock, post: 292200, member: 4885"] A chronograph lets you verify your load versus the expected velocities in the load manuals, this gives you some confidence that the pressure is in a safe range. Secondarliy, the consistency (or lack thereof) of the velocity will give you an idea if the load may be useful for long range shooting. A low Standard deviation and low extreme velocity spread are good indications of a consistent load. Thirdly, velocity is a key input into the ballistic calculators, which are used to give you an initial drop chart. AJ [/QUOTE]
