Generaly about how many rounds do barrels last, and how can i checkt to see how worn out it is?  This is in reference to a a ban gun with a 20' Barrel.  O I almost forgot, how do i tell what kind of barrel it is, Chrome mollly, Chrome lined, etc.?  Thanks

The general response for the life of a barrel is 10,000 rounds.  I've never shot out a barrel, so I don't know.  Chrome lined barrels will have a C on top of the barrel toward the front sight base.  Chrommoly won't have that.  Also you should be able to see the shine off of the chrome is the chamber and barrel.  You haven't asked but I would go with either a chrome-lined barrel or stainless steel for easier cleaning and longer life.
