I am not a professional gunsmith, just personal work. I have used four standard shank Savage 110's for a number of calibers (22-250, 243, 270, 30-06, 300WM, 300RUM, and 338 EDGE) from light barrels to 30" bull barrels, changing bolt faces as needed to suit. I made two very strong wood blocks to use with rough paper in my bench vice to hold the barrels for changing, have not needed an action wrench. Based on that I have now used barrels nuts on two Remington 700 actions turned down (I have an old Craftsman Atlas 12x36" lathe) to use 1 1/16" x16 barrel nuts from PTG, all good just as with the Savages. I have a Ruger American (1" x 16) with a barrel nut as well, works perfectly. I am building a 416-300RUM just for fun for the Remington 700 LA. My experience with all good barrels (Shilin) but one (Ruger) leads me to believe that the quality of the barrel is the foundation of an accurate rifle, with a high quality reamer used for the chamber and correct headspace, the gun will shoot fine. Of course it is enhanced by a good fitting stock, fine trigger and good optics. The Ruger American is the simplest of actions but it is SOLID: a beautiful design that evidently allows manufacturing with only a lathe and milling machine, apparently no need of a broach: no long slots. My two cents on this sunny Sunday morning.
