Great scope - Leupold Mark 4 6.5-20x50mm ER/T M5 Front Focal Rifle Scope

I mounted two of these scopes on Ruger Precision Rifles using Leupold extra high rings(extra high is required, and Wheeler scope mounting tools. I did not have to change the windage on either rifle more than 4 clicks to shoot center at 200 yards. After adjusting the vertical to center at 200 yards due to the 20 moa rail on top of the rifle), the scopes fired .75" groups at 200 yards at both 6.5 and 20 power magnification from a shooting bench and a bipod. The focus was bright and clear at both magnifications and the adjustments back and forth due to wind velocity changes returned the bullet impact to zero each time. Moved back to 400 yards and left the scopes at the 200 yard zero setting and used the mil lines on the TMR reticle to shoot 1" groups repeatedly. I am a precision reloader shooting 140 gr. ELD Match bullets. Great scopes as expected. One quarter mil click means excactly that, and returns to zero at both ends of the magnification scale. I was sighting one of the rifles for a new target shooting enthusiast, and he is able to hit the quarter sized center consistently at 200 yards. The slight open area in the center of the crosshairs is perfect for seeing such a small bulls eye at 400 yards without being hidden by an intersection of crosshairs.
