I've noticed that some bullet manufactures (Sierra) list different BC's for different speeds. Are there any free calculators out there that take these changes into account?
I am not sure if any "free on line" calculators do. But I know with Both Applied Ballistics and Shooter you can add multiple BC's and velocity limits as you want. But for most general long range use to 1000 yards 1 is usually sufficient.
