[QUOTE="Pro2A, post: 1681112, member: 17889"] Wow, if you aren't even sure of your zero distance, I wonder how accurately you know velocity, range to target, wind, and several other critical factors. How are you obtaining velocity? What chrono? How set up? How are you obtaining/measuring range? Rangefinder? Which finder? How is finder calibrated for laser point of aim? Actual tape measure to target? Are you assuming your shooting facility has correct posted ranges? how accurate were they measured? Maybe meters versus yards issue? All critical to make your DOPE not match actual impacts and thus screwing with your deviation troubleshooting. Garbage in; garbage out. Start at ground zero (pun intended) and work through all the details. only way to get accurate DOPE. [/QUOTE]
