No but I went to gun smith school .How much truing is needed.
Is it automatic that the threads are not concentric to the bolt way?
Are you a gunsmith with this as a potential jobs. Sorry, I didn't mean to take food out of your mouth.
While in school I learned most Remington actions the thread weren't true .
I had got the lathe and the tooling .
Decided it wasn't something I Wanted to do
