Be especially careful not to spring the action when applying force with the action wrench. Applying a few drops of Kroil penetrating oil ($14 from Brownells) the night before you attempt to remove the barrel makes the job a lot easier. Most factory barrels are screwed on pretty tight, so a hefty barrel vise and action wrench are needed-Brownells or MidwayUSA are a good source for both.
When everything is apart, it's a good idea to degrease the components and inspect them for defects.įor barrel removal, the Farrell Industries Barrel Vice (left) and Surgeon Rifle Remington 700 Action Wrench are solid choices. A Kleinendorst Remington Bolt Disassembly Tool ($36 from Brownells) eases the task of removing the bolt shroud, firing pin and firing pin spring from the bolt body. The first step in accurizing any bolt-action is to fully disassemble the action and bolt. We'll be discussing Remington actions here because they are most often preferred by custom riflemakers however, the basic accurizing steps can be applied to any turnbolt action. There's not any special magic to blueprinting a stock factory action-just careful attention to certain basic accurizing steps, which is what this article is all about. Blueprinting reduces the shot-to-shot variation in the motion and vibration of the barreled action and thus enhances accuracy.
Misaligned barrel threads, bolt lugs that seat only on one side, a barrel shoulder that is not square to the receiver face and so on will cause unpredictable stresses and vibrations, preventing the consistency in bullet exit needed for one-hole accuracy. For maximum accuracy, the bullet should exit the barrel at the same point in the vibration pattern. The purpose of all this is to increase the consistency and repeatability of the movement and vibration that occur when a modern high-intensity cartridge is fired.
The axis of this hole becomes the reference axis with which the chamber, bore and barrel threads are perfectly aligned and to which the barrel shoulder, receiver face, locking lug seats, bolt lugs and breechface should be exactly perpendicular.Īfter disassembly of the rifle action and bolt and removal of the barrel, the bolt body can be placed in the fixture (left), and the rear breech face and bolt nose can be trued, as well as the rear faces of the locking lugs (right). Later that winter, the gun fired a 0.149-inch group in a sanctioned benchrest match.īlueprinting (also called trueing) can also be a cost-effective way to begin competing at precision long-range matches with a rifle you probably already have in your gun safe.įor maximum accuracy, a barreled action should have a receiver with a bolt hole that is dead straight and centered in the receiver body. The first group fired through the gun-on a cold January day-was a disappointing 0.403-inch, but I guess I just hadn't gotten my shooting technique down yet, for my next four groups measured 0.275-, 0.254-, 0.201- and 0.226-inch. Hart trigger and an all-aluminum stock from Australia made by God knows who. To finish the project, I used cut-rifled barrel, a 2-oz. Many years ago, I cobbled together an entry-level benchrest rifle in 6mm PPC based on a blueprinted Remington XP-100 action. Such actions are capable of delivering impressive accuracy.
