I'd love to see a tracking text for this scope that includes shooting. I've always used a standard sight in target that has a diamond in the middle and 4 on the outside. I'll zero the gun on a rifle that I know shoots well then shoot a group in the middle. Then make the 6MOA adjustment up and right shoot a 3 shot group while still aiming at the middle target (bubble level important) adjust 12 moa down, shoot another group, rinse and repeat until the all 5 diamonds have a 3 shot group put into them. I find cheap scopes might track well until they are under recoil. I've done this with a few VX5HDs that do well for a scope at a $900 price point so I assume the Mark 5 will do similar or better.
