I was returning a scoipe that didn't work well for my intended purposes. It only seemed right to recenter it. Over the years when changing a scope from one rifle to another it hasn't been a big deal for me to just sight in again, but with an easy method like this to recenter a scope, why not? ....... Maybe the confusion for you is something else though. On modern scopes the cross hairs always look centered, but the guts are not centered in the ... well in the middle of the scope. Recentering the cross hairs gives you a good starting point on a new or different rifle. Also when you have a rifle with adjustable bases quite a few shooters like to take advantage of the superior optice available in the very center of the lenses, they like to adjust the base for windage rather than using the cross hairs. Centering gives you the very best optical portion of the glass.
NativeCraft - I did the bright light thing, but also wondered if that was necessary so I tried different lighting conditions. I believe the light used is actually the light comming through the back end of the scope. Light goes in, bounces off the mirror back at you showing the cross hair in the scope. You see the reflected image and the true inage. When the two meet the scop0e is centered. Once you get the hang of it this always works reguardless of lighting conditions. My initial problems was caused by using the wrong side of the hand held mirror. The mirror had a standard glass and a magnifying glass. The magnifying side didn't work well at all. /ubbthreads/images/graemlins/smile.gif
