The Kreiger uses cut rifling and the Douglas uses button rifling. Cut is more expensive than button and will usually last longer. As for accuracy, they can be just as accurate as the Kreiger but will usually not last as long. Then again the Douglas is cheaper than the Kreiger. Both can be excellent barrels. In fact, I have one of each. Both will shoot just as well as the other. However, that being said, it is very, very important that the chambering job be done correctly. You can have the best barrel in the world, but if the chambering job is bad it will be a POS. To do a good job the smith will need your bolt to set headspace correctly or you can buy a bolt with the barrel. John Holliger of White Oak Precision or Frank White of Compass Lake Engineering will do right by you. Do a web search for their addresses.
