wear or bad cleaning habit’s

Shooting

Also occurring when you lead the match and someone kindly re crown your brl with a screwdriver or an Allen wrench. Well known in France.
On my own I had a bumped scope during a National in 2016.

when a barrel is recrowned on a lathe, does the barrel need to be removed from the action?

Not if your lathe head stock is short enough or bore big enough to accept the action.

Yea, people bump your stuff. One weekend shooting front and rear bag. Just enough to be a PITA. That couple is gone.
I think, they also moved my powder measure. That was the first time, they were shooting with us. Learned to mark both with a sharpie....

I have done the re crown thing a few times. It did not help the barrel. And was a waste of money. 30X magnifier or Teslong bore camera can tell you a lot.

If you're unlucky like I am when you you push a tight patch through the bore, the mismatched combo of rod end thread direction and barrel twist direction can cause the jag and or adapter to unscrew.. Be sure to tighten it back up before pulling the rod back through. Dragging that little gap back over the crown can damage it and the rifling or so I've read. A good reason to consider counterboring your muzzle end.

Zippy, Dwight Scott re-crowns after every weekend.

It is the last thing the bullet sees. I keep in mind its the last of the parts I can control.

What about the weekends he is Skeet shooting or fishing??????? And he has his own lathe. Well, maybe not any more. He closed shop.

A good reason to run a tuner, makes it a bit tougher to do any crown damage!
