Make sure you clean it well first because copper fouling can hurt accuracy , the foaming copper cleaner works, Clean from the breech always and clean until the patch comes out white(not blue).
Shoot it until the accuracy degrades to the point that it unacceptable to you, I have seen barrels go 20,000 rounds and heard of someone shooting 50K before a bullet keyholed.
They can not be rebored, just have a new barrel installed.
