I have been considering buying a new rifle. I want one in .204 Ruger. In the future I intend to buy another barrel for this rifle in .223 Rem. I was looking at the one of the new Model 11 Trophy Hunters in a local shop today and noticed that they have changed the barrel nut to a smooth surface instead of the slotted nut that I am accustomed to seeing on Savage rifles. I am wondering how you can change out the barrels with this type of smooth nut. Do they have another wrench for this type of nut. I couldn't take off the stock to see if there was any slots on the underside of the barrel nut. I want to be able to use this action for .223 in the future if I want to, so I need to know if it is possible or not. Thanks.
