I am changing from a 165 SGK to a 168 SMK in my 30-06. I have already done a 400 yd ladder test and the rifle shows to be liking a load that is only .2 gr higher than my SGK in H4350. Which is good - everything is a real go in the loaded round department. But here is the deal: I would like to know the FASTEST and most ACCURATE way to get the scope dialed in for this new load. Would it be best to re-zero at 100 yds and shoot in increments out to 900 yds, noting the drops in inches and make a drop/come-up chart from that or what? Ideally, I would like to have the data I need to make a drop chart in a day and with a minimal amount of shots - less than say 50 if possible. Then come back a second day and confirm scope clicks, etc. I want to get the data - accurately - as quickly as possible so I can using my powder and range time for steel , etc. How would you go about doing this? Thanks for the help.
