7mm Backcountry Trajectory Calculator
The 7mm Backcountry represents the modern evolution of the venerable 7mm family of cartridges. These default settings showcase its impressive ballistics: a 170-grain bullet with a .645 ballistic coefficient traveling at 3,000 fps. When zeroed at 100 yards, this combination delivers the kind of flat trajectory and retained energy that makes it an excellent choice for long-range hunting situations.
While these baseline numbers highlight the cartridge's capabilities, actual field conditions can vary significantly. Our calculator allows you to account for every variable that matters in the field. Whether you're hunting at elevation where the air is thin, compensating for crosswinds on an open ridge, or taking angled shots in steep terrain, you can input your specific environmental conditions to generate precise firing solutions.
Examine the trajectory chart and table below for a detailed look at this round's performance in 25-yard increments out to 500 yards. Want to see how your specific load performs under your hunting conditions? Just click the Modify Calculation button and input your data. From atmospheric conditions to wind speed and shooting angle, you can fine-tune every variable to match your exact scenario.
