Strelok. I use it for two different rifles with two different types of scope adjustments. A 6.5X284 with .25 MOA adjustments and a .300WinMag with .1 Mil-Dot adjustments.
Once you get your rifle/scope information and weather conditions loaded it's just a matter of lazer ranging your target, inputting that number in and hitting "calculate" and make necessary scope adjustments. In a hunting situation it takes less than 10 seconds. Used it this year on a buck at 480yds in the last minute of legal shooting light.
But, I didn't get the buck. It wasn't the app, scope or rifles fault. All mine, as usual! Had been working crazy for prior two weeks and had not checked my scopes zero. For some weird reason it was shooting 14" to the left, with no help from the wind. Live and learn. JohnnyK.
