Use this calculator to generate ballistic drop charts and compare various loads and environmental conditions, such as temperature and incline (slope). Once you set up a personal account to use the Vortex Long Range Ballistics Calculator (LRBC), you'll be able to store your favorite rifle/loads as well as multiple range or hunting conditions. The Vortex LRBC is an invaluable tool for the serious long range shooter!
