I always grab a few labels when I'm in the P.O,and just draw a black ring about an inch in diameter on it. I line mine up at 100 yards,because most of my scopes have the paralax fixed for that distance.I don't line mine up a little high like some folks.My Dad always liked his lined up a little to the left because he claimed right handed shooters pull a little to the right. The way I look at it is if you line one up dead center then a slight tilt of your gun while hunting won't amount to anything..
