How To Use

Please Note: this ballistic calculator can only process supersonic velocities, transonic and subsonic velocities will cause errors.

The ballistic calculator will provide all the variables of your shot at a provided range. To use the calculator, simply fill in the input values (blank white boxes) in the large black box. By default, we only need four values to give you a good idea of how your shot will behave: target range, bullet weight, muzzle velocity, and ballistic coefficient. If you want more accurate readings, we recommend you fill in all the remaining values but they aren't required. By default, we populate those values with the U.S. averages across the nation.

The second black box is if you want to populate a table from one range to another by a given increment. We also populate these values by default with our most common competition requests, but you're free to customize them to build the table you need by changing those values as well. Click the yellow button once you're finished making sure to leave all your ballistic information in the top black box, and the calculator will provide a table for you to use. Keep in mind the first black box holds all of the data used to build the tables, so it needs to remain filled out if you want to build tables.

Clicking the question marks will display help text just above the yellow buttons. They provide explanations and helpful tips about required inputs and, when applicable, will give you the U.S average in case you delete one of the values and need it again. In the event you generate an error, the error text telling you what went wrong will also be displayed here.

We don't have a great way to export the table quite yet, so we recommend you copy and paste it into another document or take a screenshot to print for later use.

Thank you for using the Caldwell Ballistic Calculator to help you eliminate the variables that make you miss!
