Lapua hunting app

I never quiet got the hang of these things, always get the moering and chuck it after a few hours.
My brother in Aus loves the Strelock App, his rifle is so intune with the app that he shoots deer at 1140 m from his porch. I was truly amazed at his dial in a distance a its a given, every time.

The apps that I have tried never had my model scope on them, just something I recall when I think of apps.
