We all have different ideas and experience with different barrels. As for comp. barrels I've had best luck with Shilen, Krieger, Obermyer, and 1 Rock Creek. I've used Broughton barrels when Harold was making them, Turbo barrels when Flash Ebert made then, Bartlien, Douglas, and I think that John Holliger used a Wilson on my AR that he built. All of my hunting rifles are minute of animal. Lothar Walther has a LW50 stainless that I think is a PH steel. They ain't the easiest to chamber, but more feed and speed make a difference. I haven't had a very good one.
