The new Kestrel 4500 has Horus balistics program integrated. The cool part is that once the basic info is loaded, you can get an instant firing solution based on the exact conditions of THAT moment every time you touch the compute button.
The Horus program also allows you to "FLEX" the computer generated trajectory with what you bullet is REALLY doing.
The balastician from Horus we spoke to at SHOT explained it far better than I have, but the theory seems sound.
Now if only we get some decent shooting weather to go out and try it in the field.....
