I have built several rifles now on savage actions. All the barrel nuts came off relatively easily. Today I removed the barrel on my 10FP, which I had bought new a number of years ago. I have never seen anything like it! I literally beat the snot out of the barrel nut wrench, and bent the screw in the action wrench which goes thru the wrench into the action. I have never seen anything like it - I literally forged flats on the nut wrench I was hitting it so hard! It finally came loose and I was able to rebarrel. Why does the factory snug them up so tight? Damn.....
