Hornady Ballistics

With the correct environmental conditions input and load ballistics the adjustments recommended by the 4DOF are usually spot on from 600 yds in. 538 is the farthest I’ve taken a muledeer with it, but that was a -13 degree decline with a 24 mph crosswind (175 grain Fusion Tipped in 7PRC). The shot was a little high but it dropped him in his tracks. The previous year I took one at 505 yd with an old 30-06 using the 4DOF calculations. When I first started using it, I’d compare its output to my own calculations and it was usually pretty darn close. Outside of 350, I trust the app. more than my own math and use it all the time now. A free way to get environmental conditions if you don’t have a Kestrel or similar instrument to pair with the 4DOF app is to download the Burris Connect app, set up a rifle profile and then press “request environmental data” in the “ballistics” tab. Then type that info. into the 4DOF app. Works for me anyways.

It crashed every time you try to select ammunition. I’ve deleted and reloaded the app 3 times and it never fixes the problem. Don’t waste your time on this app.
