Don't know if anyone else saw this, but in the Sept. 2011 issue of Shooting Illustrated, they offer a fairly simple but interesting drill that will test your ability to dial your scope correctly (under time constrants) and the by product is that it is a tracking drill for the scope itself. It's shot at 100 meters or yards and has the come ups and windage in Mils and MOA. You only need 6 rounds. Go to www.ShootingIllustrated.com "Tips" section, then click on "Drills" which allows you to print the target. A little tip. If you shoot the drill with MOA turrets, you WILL NOT end up back at your zero like the writer implies. Good luck and have fun.
