For those LR/PRS shooters out there who use a ballistic app, How do you go about truing your app? I've always gone about it by truing the MV, but I find that the app doesn't match my real world drops. I trued my app at 450 yards first, then I moved out to 800 yards and trued again. But I find that it doesn't match up if I move to a different location.

I use Strelok Pro, but I'm wondering what others are using and how you go about your truing procedure.

I want to have it correct, so that when I go up in Altitude that the app will be able to correct for the difference in altitude, pressure, and drop. I don't want to have to true my drops everywhere I go.

Just read a post on another site that says I should true my MV out to 500 yards and the true the BC at 700-800 yards. The statement implied that if I do it that way, then my drops will be correct no matter where I shoot.

What do you all do? And does your app match up to your yardages between 100 and 1000 yards?

Thanks,
