3. Power Scopes Leupold variable power scopes allow you to select from a range of magnifications to suit your particular rifle cartridge and shooting needs WARNING Do not lubricate the power selector ring doing so is unnecessary All variable power scopes have a power selector ring in front of the eyepiece assembly Turn the ring to align the number indicating the desired magnification with the indicator on the body of the scope UNDERSTANDING PARALLAX Parallax is the apparent movement of the target relative to the reticle when you move your eye away from the center point of the eyepiece It occurs when the image of the target does not fall on the same optical plane as the reticle This can cause a small shift in the point of aim Maximum parallax occurs when your eye is at the very edge of the exit pupil Even in this unlikely event our 4x hunting scope focused for 150 yards has a maximum error of only 8 10ths of an inch at 500 yards At short distances effects of parallax do not affect accuracy using the same 4x scope at 100 yards the maximum error is less than 2 10ths of an inch It is also good to remember that as long as you are sighting straight through the middle of the scope or close to it parallax will have very little effect on accuracy INSTALLING A LENS ATTACHMENT Many Leupold scopes offer threaded objective and eyepiece rings to allow for the attachment of lens covers and a variety of Alu mina a
