[QUOTE="JDD, post: 2306962, member: 102774"] I worked 2 years as a RSO and volunteer instructor at a 1100 yard range. The app work some do more than others. Applied ballistic pro is dirt cheap and has a tone of video support and books available to teach you external ballistic. The saying junk in junk out is 1000% correct. Go back to basics. Research how to run a tall target test. Verify your rig is dialing straight up and down, there is a way to measure the accuracy of the clicks while running the tall target. Do so.AB pro allows you to input a constant to adjust if it’s off. You won’t likely notice with the grindel at 300. But with true long range cal at a 1000 and beyond you will. Once you know it dialing straight up and down, and the measurements are right the set your scope level using the lines you drew on the tall target. The chronograph should be close enough , if your rifle is not shooting one moa at a 100 or better don’t waste too much time and money on this. 3” groups at 100 will be 9”!groups at 300. You won’t be consistent enough to get a good read on what’s it doing. Always dial when confirming data. Try to true your data at the distastance just south of it going trans sonic if you have the range available, if not as far out as you can reach with the understanding it’s not ideal. Once you verified data on your dials get a target with a grid you can read at a 100 , 200 etc then a bull or square and verify your retical. You need to know if you have a first or second plane scope and what that means to you. My post is to not necessarily to try solve your problem but to illustrate what you don’t understand and start you down the path to correct that.you have lots of study to do just as we all did when we started down the path [/QUOTE]
