Just wondering if anyone here has read or seen the new ballistic program that Hornady recently released. (4 Degrees of Freedom).... I just read an article in G & A about it. It uses a drag model as apposed to a BC model. Supposedly it's more accurate for firing solutions past 600 yards. I just ran a theoretical solution thru my Strelok app and the 4DOF. At 1000 yards, I had a difference of 2 clicks more on the Strelok than the 4DOF. It is all theoretical for me, as I still haven't trued my drops on my Strelok app.

Anybody have any thoughts on the "new" ballistic program? Has anyone actually used it yet in real world, that can validate it's accuracy?
