[QUOTE="BrentM, post: 2627972, member: 61747"] Terminal ballistics is an interesting topic. Temp and elevation play a large factor in drop. Additionally, you will need to understand slope angle affects. Now, having a custom turret is fine if you fully understand the limits of it. I think you want to simply range, dial, and shoot. Ok, that works fine to a degree within a set of parameters and it is not ideal with slope angle. In the case of shooting at 1500 ft and 60f vs 8500 at 35f is 2.5” for my prc at 600. Nothing to worry about. If you introduce 15 degree slope you’re another 2”. Again, not a lot to worry about but you are now around 4” of error. If you have a moa rifle/shooter, you have 6 plus 4 or 10” of error. That’s too much for me to be comfortable. My suggestion is to get an app or go on line and dial in the ballistics. You could also ask for help here and one of us could run the numbers. [/QUOTE]
