[QUOTE="NikatKimber, post: 2893359, member: 423"] I used muzzle velocity from data.hodgdon.com, rounded down. Bullet coefficients are available from most manufacturers. The ballistic calculators are usually considered a rough estimate to get you close, or on target. Your gun and load will almost always be a little different. So you'll have to set your own dope, and if you have a chronograph you can double check your muzzle velocity, and if it's different than you estimated then you can further refine your calcs. [/QUOTE]
