I have had good luck with factory barrels, never having a problem getting one to shoot. Others have. In my case the main reason to get a custom barrel is to get something not available in a factory barrel such as a chambering unavailable from the factory, or a twist rate etc. that meets your needs. Other folks wouldn't consider factory barrels acceptable and would not consider using them at all. True custom barrels are going to cost more. The only barrels that I know of that are cheaper are the Bergara barrels made in Spain to fit Encore's. Early experience with them seems to be fine, but there aren't all that many out yet.
