I have a very nice Savage model 11 in 22-250. I want to change it out to something else. I have been looking around at barrels and first wanted to do a 260. But that barrel is a little more than I wanted to spend. I am wanting something none of my hunting buddies have so I looked a little more. I found the 358 WIN Adams & Benett barrel for a good price. I researched the 358 and I like it. So I know I am going to need a barrel and I plan on buying another barrel nut just in case the smith messes up the on there. My question is would I need a new bolt face and would I have to modify the magazine in any way? Thanks
