1. A method of correcting the cant of a firearm, said firearm having barrel, a receiver section, a mounted scope reticle with a viewport containing vertical and horizontal cross hairs, and a bubble level located posterior to the receiver section having a central axis that is perpendicular to the central axis of the barrel and a centerline that is parallel to the central axis of the barrel, comprising the steps of:
placing a view target, such as a plumb line or other vertically straight element, some distance away from the location of the firearm where such view target has a clearly visible vertical element as seen through the scope reticle; placing the firearm in a securing means with the barrel pointing toward the view target such that the firearm may freely rotate about the central axis of the barrel and then be secured in a fixed position for firing at the view target; loosening the scope clamping means of the reticle such that the scope and vertical and horizontal cross hairs within the viewport may be rotatable about the center axis of the reticle; orientating the firearm so that bubble is in the center of the bubble level and secure the firearm so as to prevent rotational movement of the firearm; and rotating the scope and cross hairs of the reticle such that the vertical cross hair aligns with the vertically-straight element in the view target then tighten the scope clamping means to prevent any rotation of the reticle, |
