Claim Text:
1. A method of increasing rifle accuracy by converging bullet velocity to a given distance, comprising the steps of: providing a rifle having a stock having a butt section and a forearm section with a stock recess, an action with a front face and a rear face, a vertically depending recoil lug attached to the front face of the action and a one piece barrel having a barrel shoulder at one end which extends outwardly from the recoil lug and which has a distal, muzzle end; mounting the barrel in free-floating fashion within the stock recess so that the barrel extends from the recoil lug and rifle action and so that nothing is touching between the stock and the barrel forward of the recoil lug, the barrel being cut to a specific length and muzzle weighted to tune the barrel to the longest expected shooting distance, the barrel having a solid bull muzzle end with a recessed crown, and wherein the barrel weight which exists in front of the recessed crown is in tune for one specific distance only, the barrel being provided with a narrowed mid-section which produces an intentionally wider barrel upswing and an increased whippy vertical bending action and a thus a wider tune spectrum on the vertical upswing of the barrel under recoil; extending the rifle action with a tensioning bar which is welded to the recoil lug, the tensioning bar extending in a generally horizontal plane outwardly from the recoil lug in the direction of the barrel; providing an adjustment knob which extends vertically downward from the rifle forearm at one extent and which contacts the tensioning bar at an opposite extent, thereby restricting the tendency of the action to lift up out of the stock recess under recoil; using the tensioning bar and adjustment knob to control the vertical bending and upswing of the rifle barrel under recoil so as to converge velocity to a given fixed distance, whereby ammunition with varying velocities will hit the same spot on a target at the given fixed distance.
