Krieger stainless steel competition rifle barrels usually appear on the top finisher's equipment lists in benchrest, high power, long range, and Palma competitions. Many top gunsmiths are recommending Krieger barrels because of their consistent quality and performance. This consistent performance is due to a combination of the processes Krieger employs - from 416 stainless steel made to their own specifications, the singe-point cut - rifling method used to rifle the barrels and the cryogenic treatment each barrel relieves before it is machined. 6mm Heavy Varmint Benchrest; .237 inch bore diameter, 269 inch blank 1:14 twist 1.25 inch breach diameter tapering to a muzzle diameter of .900 inch.
