I was cruising around the Vortex USA website and noticed that they now have an on line Long Range Ballistic Calculator (LRBC). You need to create an accout with them, but that is easy and then you can customize rifle info, load info, environmental conditions, pressure, incline etc. You can then print out a calculated drop chart, take it to the range and validate it, make any required corrections, and then go back to the LRBC and input the corrections, it will then print a perfect drop chart for you, AND you can order custom made Trajectory Matched Turrets! Of course the turrets are only made for Vortex scopes, and they only work on the Razor and Viper PST. But is a great tool for any long range shooter, you can even put in wind speed and direction and it will give you the inputs for making corrections for wind conditions. Amazing tool and all free, except for the turrets, you have to pay for them!
Great new tool on Vortex USA web site!
