HA!
I was using a 6.5x55 with the 140 Partition (BC .496) at 2700 fps. The scope was a 2-7x Leupold. When sighted-in 2" high at 100 yards and set on 7x, it puts the bullet right at the tip of the bottom post at 400. Old-fashioned, but effective...
Oh, and I had the scope cranked up all the way up 7x, and was still able to see the deer! That's because the field of view is about 5-1/2 feet wide at 30 yards....
