Q. I have a (Nightforce, Leupold, Bushnell, etc) scope with MilDot Recticle
Is that in your library of recticles? If yes which one would I have to choose and if no is there a chance you could include it in one of your next updates?
A. MilDot - this is standard reticle and it already listed in my program, so you can select from the list reticle with name "MilDot (USMC)" and use it.
Q. I purchased Strelok Pro and it did not install over Strelok (free). How do I transfer all my data from the Strelok to Strelok Pro?
A. Start Strelok and make "Backup rifles".
Locate folder Strelok in internal memory or external sd-card. The file rifles.srl must be in this folder.
Locate folder StrelokPro in internal memory or external sd-card.
Copy file rifles.srl to Google Drive root folder.
Start Strelok Pro, open Settings screen, tap Google Drive button and make Import rifles from Google drive
Q. What is your definition of "scope height"?
A. Distance between center line of scope and center line of bore. Like here.
Q. Could you try to explain how to use "truing" feature?
A. Suppose, you input muzzle speed as 2648 f/s
Shoot at distance bigger than zero distance. Suppose this is 800 yards. Calculated elevation for this distance is 26 MOA
Find out REAL elevation is needed to hit the target. Suppose this is 27 MOA.
On the trajectory validation screen input Distance as 800 yards and Elevation as 27 MOA
Tap button "Calculate" and speed at which elevation will be equal 27 MOA will be calculated. It this case, it will be 2609 f/s
Tap button "Use this velocity" and this calculated speed will replace your current cartridge speed (2648->2609) and screen will be closed.
On the main screen tap "Calculate" button and you will get calculated elevation which equals REAL elevation and equals 27 MOA
Now you can input any distance and hit the target.
