I'm not sure I understand the thread.
Yes, there is a thread in the gunsmith forum about 8 pages long with everyone commenting on the performance of nut barrels (and how they can't be as good as a shoulder pretty much). When I asked if anyone had ever made a nut barrel, there was total silence. I've made about 400 of them, I've tested dozens of them and the barrel doesn't know if it's a nut or shouldered (of course).
Then, one of the members that is a well known high level shooter and gunsmith tested a barrel with both types on the same barrel. The nut actually agged smaller if there was any difference at all.
No more replies after that.
Honestly, I can't believe at this point after decades and decades of use, how people can say the things they say about nut barrels. I get the "looks" part. Whatever that means. But other than that, the rest of the nonsense is just silly and total baseless.
The nut has MANY advantages. So, does the shoulder too. You can make a nut barrel into a shouldered barrel with some loctite. So, it can really have the same advantages as a shoulder.
A Savage will have to be fitted. It will not be a "prefit" because Savages don't hold headspace.
Some of my best shooters shoot the nut even though they could order the shouldered prefit. I shoot the nut pretty much every barrel I test, as does my family and shooting friends.
