Telescopic sights for firearms, and related methods

A method of adjusting a telescopic sight having a main housing having a length extending along a lengthwise axis between a first end and a second end, an objective lens assembly positioned within the main housing proximate the first end thereof and configured to create an image of a distant object, an ocular lens assembly positioned within the main housing proximate the second end thereof and configured to present the image to a viewer, an optical element assembly positioned within the main housing and between the objective lens assembly and the ocular lens assembly, the optical element assembly including a reticle piece containing a reticle viewable by a user when the user views the image presented by the ocular lens assembly, a first adjuster positioned external of the main housing and operatively coupled with the objective lens assembly such that movement of the first adjuster causes axial movement along the lengthwise axis of a component of the objective lens assembly for removing parallax between the image and the reticle, and a second adjuster positioned external of the main housing and operatively coupled with the optical element assembly such that movement of the second adjuster causes axial movement along the lengthwise axis of a component of the optical element assembly for removing parallax between the image and the reticle, the method comprising:

• aiming the telescopic sight at a first distant object at a location farther away than an intended shooting range,
• moving one of the first adjuster and the second adjuster to remove the parallax between an image of the first distant object and the reticle,
• noting an index point for the other of the first adjuster and the second adjuster,
• aiming the telescopic sight at a second distant object at a known distance within the intended shooting range,
• moving the other of the first adjuster and the second adjuster to remove the parallax between an image of the second distant object and the reticle, and
• noting a first range point for the other of the first adjuster and the second adjuster corresponding with the known distance to the second distant object.

A method of determining a distance to an object using a telescopic sight having a main housing having a length extending along a lengthwise axis between a first end and a second end, an objective lens assembly positioned within the main housing proximate the first end thereof and configured to create an image of a distant object, an ocular lens assembly positioned within the main housing proximate the second end thereof and configured to present the image to a viewer, an optical element assembly positioned within the main housing and between the objective lens assembly and the ocular lens assembly, the optical element assembly including a reticle piece containing a reticle viewable by a user when the user views the image presented by the ocular lens assembly, a first adjuster positioned external of the main housing and operatively coupled with the objective lens assembly such that movement of the first adjuster causes axial movement along the lengthwise axis of a component of the objective lens assembly for removing parallax between the image and the reticle, and a second adjuster positioned external of the main housing and operatively coupled with the optical element assembly such that movement of the second adjuster causes axial movement along the lengthwise axis of a component of the optical element assembly for removing parallax between the image and the reticle, the method comprising:

• aiming the telescopic sight at the object,
• moving one of the first adjuster and the second adjuster to remove the parallax between an image of the object and the reticle,
• determining the distance to the object based on a position of the one of the first adjuster and the second adjuster.

• aiming the telescopic sight at a first nearby object within an intended shooting range,
• moving one of the first adjuster and the second adjuster to remove the parallax between an image of the first nearby object and the reticle,
• aiming the telescopic sight at a second nearby object within the intended shooting range, and
• moving the other of the first adjuster and the second adjuster to remove the parallax between an image of the second nearby object and the reticle.
