What is the name of the app?
I carry a ballistic card for my home loads. I have one for each rifle/bullet pair.
I’ve not found wind to be much of an issue...4-5 inches over 500 yards is the worst correction I’ve seen.
Angle is BIG.
I have the advanced version of this. Think it is only $14.99 now but worth many times more than that. I have been using it for many years and have upgraded along the way.
