There are actually many Match Grade Cut-Rifle barrel makers out there. Many are only know in benchrest circles. They are considered Boutique makers because unlike Krieger they have less capacity and longer wait times. I have Cut Rifled barrels from Brux, Krieger, and Bartlein barrels. All are great, can't say I like one over the other. It is believed (by Cut Riflers) that Cut lasts longer than Button. Also, they say because the button presses the rifling into the steel any inconsistencies in the steel will show were the button ran over (high and low spots). This is why Shilen and Douglas offer different grades based on air-guage results. Cut rifling cuts the steel and inconsistencies are not noticed, because the cut is the same each time increasing in depth.
