Tested my Mark 4 today how good it track and below was the result. Shooting two sighter at the center target to established zero I'm suppose to dial 3 MOA up and 3 MOA right to shoot at the upper right hand target but got totally confused on the windage. Does the Mark 4 has .25 MOA/click or .5 MOA/clicks. So I dialed 6 clicks right and discovered my mistake as you can see in the target. Continuing with my test I dialed 6 MOA down to shoot at the next target at the lower right hand corner and then 6 MOA left to the lower left hand target then 6 MOA up to the upper left hand target and then 3 MOA right and 3 MOA down to arrive at the center target. As you can see further testing is neccessary but I think this scope tracks well. what do you think guys?
