Can I use the calculator for any projectile type?

The tool accepts standard bullet parameters including weight, diameter, sectional density, and form factor, but accuracy depends on how well the form factor matches the actual projectile shape.

Do I need to know the ballistic coefficient to use the trajectory calculator?

No, the BC calculator estimates the coefficient from velocity measurements, which you can then enter into the site’s main trajectory calculator.

Is the calculator free to use without creating an account?

Yes, the tool is available online for free without a mandatory paid plan or registration.

What if my downrange velocity is measured in different units than muzzle velocity?

The calculator requires consistent velocity inputs; check that both values use the same unit system before submitting.
