What is the purpose of a "Dope Card" in marksmanship?

The purpose of a "Dope Card" in marksmanship is to record ballistic data and elevation changes. This card serves as a quick reference tool for shooters to note and track critical data that influences their shot accuracy. It often includes information such as windage, elevation adjustments for different distances, atmospheric conditions, and bullet performance characteristics. This data is essential for making precise adjustments during shooting sessions, especially when engaging targets at varying distances or under changing environmental conditions. By utilizing a Dope Card, shooters can optimize their performance and consistency on the range or in the field.
