I’ve been playing with the Element Ballistic Apps lately and noticed something not matching to my other ballistic app. I inputted the same parameters as I have on StrelokPro and the result on the Element Ballistic app is showing POI 0.45 inch to the right on a target of 100 yards even though both app has the wind speed set to zero. This is based on a right rifling twist rate of 1:19 and if I change the twist rate to left then the POI shifted to 0.45 inch to the left. If I set the app to smooth twist rate then the POI has not shifting. Do I have a bug on this app or there is something more to this. Any ballistics gurus can input on this subject.
