[QUOTE="MNbogboy, post: 942128, member: 18849"] Agreed with Brandon on all points. Before you order your turret a thought might be to do some drop tests at longer range...With your rifle shooting as good as it does a drop test should prove the reliability of your Chrony... Using the results of the actual drop test you can back pedal through a ballistics program with your advertised bullet BC, temperature, barometric pressure and scope height.....The velocity the program shows that gives your measured drop should be very close to actual....(advertised bullet BC will now become the biggest variable)....All this information is necessary for the turret maker anyway......(I have had two Chrony's over the years and have seen them both very consistent and very erroneous depending on how you handle the ambient light conditions)....But a drop test at 500 or 600 yards has proved a good way to confirm the chronograph. Good luck, Randy [/QUOTE]
