Cut rifles are very good. However, of the 'buttoned' variety there are two: The standard button-rifled barrel, where a mandrel is simply pulled through the barrel, and the cold-hammered variety - with those, the barrel is hammered into the mandrel, thus forming the rifling in a way that is far superior to the old pull-mandrel method. Some, like Steyr, also twist the entire barrel during that process, adding rigidity. Those barrels are as accurate as cut rifle barrels.
