[QUOTE="kcebcj, post: 855169, member: 10391"] You almost got it. What is absolutely necessary is you prove the load. The ballistic program has to match your actual drops and you can get the two to jive by manipulating the velocity or the bullets BC. I zero at 100 yards shooting through a Chronograph and obtain a velocity number. I run that in Exbal (ballistic software) creating a drop chart at 20 yard intervals. With that chart I shoot at 330, 460 and 800 yards. I can do that from my bench out the back door so it's pretty easy for me to fool with a load. Done shooting I gather the targets and determine the error at each distance. In Exbal there is a tool "Trajectory Validation" and when the appropriate info is entered it determines the actual velocity of your load making the drop chart figures match the actual drops. It gets it pretty dang close if your zero is accurate. Once you have proven the chart it's good to go. If you change elevation or if the temp drops like 50 degrees then you must enter the new info to update the chart. A ballistic program like shooter on a iPhone is the way to go. With the proven ballistic info loaded all that needs to be done to update is enter the current environment info. shot angle and wind stuff and it spits a accurate hold. I may have overlooked a few things but yeah range it, crank the turret and shoot. [/QUOTE]
