ballistic programs will get you in the ballpark but you need other info, muzzle velocity, barometric pressure if ya wanna hit past 600, and your actual bullet BC, not what the manufacturers say but your actual BC. there are countless good programs, all they are is a calculator geared toward ballistics, download one on your phone. I run exbal (the same one jeep has only earlier, see I taught him well!)
