Krieger, Lilja, Pac-Nor, HS-Precision, Border, Lothar Walter and so on make good barrels. Good receivers can be had by the likes of Kelbly, BAT and so on. If you're on a budget, however, do not get obsessed with the barrel, as there are 'weaker' parts of the gun set-up that have priority: Get a good trigger, like a Jewel or Timney and have a good stock, like a McMillan or Lone Wolf, custom-bedded. The money spent on this will get better results then a cut-rifling barrel with a bad stock and trigger. Something often also overlooked is the scope. The vast majority of scopes will not allow you to shot 1/4 inch or better groups as they are not precise enough. In a German gun magazine, there was a big test to that effect. Only The Schmidt & Bender 'P' series, Swarovski and Nightforce came out perfect in that respect. My personal experience confirms that.
