Just got my 06 sighted in at 100 yards a week ago and I've watched several others do it the same way. Start with a large enough target on the hundred yard range to see where it's hitting and then start making the scope adjustments till your getting real close to the bull. At that point, fine tune where it's hitting with a click or two in whatever direction you need to move the point of impact to get it on dead center. Then move to the 200 yard range and find out how much holdover you need to hit the bulls eye there. I shoot three shot strings so the barrel doesn't get too hot and shoot the .204 while the 06 cools down--------
