Ballistics & Density Altitude

You have purchased a set of Kriterium Long Range Data Cards and want to complete the Ballistics Module with your elevation & windage data to match your rifle and ammunition. The Ballistics Module works around the concept of density altitude, which combines air temperature, pressure and humidity into one single value. This makes it faster and much more efficient for shooters to adjust to changing atmospheric conditions. When in the field, just determine actual density altitude and select the corresponding color-coded range card.

Generating Ballistic Data

For the Ballistics Module to work correctly you need to generate ballistic data in advance for ten color-coded density altitude range cards. There are two ways to generate this ballistic data and if you are new to precision rifle shooting, we recommend the easy way.

The Easy Way

Download the Excel-file below and fill in all required weapon and ammunition data along with your e-mail address and the product support code found inside the product packaging. Send us the completed Excel-file at ballistics@kriteriumgear.com. We will run all calculations in our custom built G1/G7 ballistic calculator and send back a PDF. Transferring the data from PDF to your cards will take only a couple of minutes.

Note: Generating ballistic data is a free service and the terms of this service may change at our discretion at any time. Usually we are able to send you the PDF-output file within 48 hours after receiving your Excel-input file, but in some cases it may take longer.

The Hard Way

Advanced users who favor full control over their data can also use their preferred ballistic software to generate the data for completing the Ballistics Module. This requires one (1) calculation for your zero (ZER), one (1) calculation for determining the elevation adjustments due to muzzle velocity temperature change (TEM) and ten (10) calculations for each predefined density altitude range card (-1000 to 3500). For calculating those ten range cards, use the corresponding atmospheric input values you find on the International Standard Atmosphere (ISA) card.

Safety Warning: Safe gun handling is your personal responsibility at all times. Always verify your actual point of impact before using any of the provided ballistic data in any hunting or tactical application. If you are uncertain about any of the provided data, seek qualified instructions.
