If you want to zero for 50-200 meters at 10 meters and save some walking just use this ballistic calculator to get bullet drop at 10 meters with your bullet and location data (provide that zero is at 50m).
Then put two dots on target, one on the middle, another below at distance you have calculated for bullet drop for 10 meters.
From 10 meters aim at the upper point and adjust optics so it would hit at lower. Done.
For my location and bullet, I get 3.46 cm bullet drop for 10 meters distance.
