[QUOTE="7mmTikkaShooter, post: 2591392, member: 92915"] This is important as well.👆B.C.’s are not always as published and are rarely what you’ll get after bullet deformation after being pushed through you barrel. Typically they’re close enough but to match as shot data, I like to tweak this number first in my calculator rather velocity for this very reason. I am meticulous in getting as much environmental data as possible before I do though. You can be spot on B.C. and velocity but if your calculator is off by 20 degrees the air density will be different and you will end up with a different result than the program kicked out. As stated before I think your target speed and wind values are what’s giving you fits in this scenario. Try zeroing those and input your environmental data as close as possible. I bet you’ll be surprised by the changes. [/QUOTE]
