I'm doing my first build using a Savage action. I ordered and received a new barrel from a supplier I don't want to name at the moment. I don't want to bash them until I'm sure the problem is the barrel and I give them a chance to make it right. But I also want to make sure I didn't make a mistake before contacting them. Since the donor rifle had a smooth barrel nut and I had to use a pipe wrench to remove it, also ordered a new knurled barrel nut as well. I started to assemble the pieces this weekend. The first problem I ran into is that the barrel nut does not want to go on the new barrel. I greased the barrel threads and can't get the nut to turn without applying what I estimate to be between 20 and 30 ftlbs. When I tried to thread the action onto the barrel I run into the same problem but I didn't try to put as much pressure on it as I did the barrel nut. If I do, I'm pretty sure I'll put some scratches on the action. The new barrel nut goes on the old barrel with minimal effort. I measured the threads of the new barrel at 1.061". I checked the old barrel and they are 1.053". From my research, the threads on the shank should be 1.055". Am I missing anything? Is this the normal level of effort required to thread the barrel nut? Does this sound like a manufacturing defect? I know Savage makes an action for magnums that is bigger, but are there other size variations in Savage actions? I just want to make sure my expectations aren't wrong. Thanks for your input.
