Shilen,Hart,Broughton,Lilja,K&P,Chanyln,Pac-Nor,(the old black star barrels)are some of the barrels that I have on rifles. Krieger,Spencer, and Schneider are afew more that are pretty good. I've always gotten SS select match grade barrels except one Douglas and Wise-McMillian which are CM. I wouldn't buy a barrel just because it winning somewhere I kind of look at the company and product. Shilen makes a pretty good barrel. You might want to look at the Broughton 5c barrel you will gain alittle more velocity you can pull up there web site and my next project will be a 300wby with their 5c barrel. I gave up on trying to get a Obermeyer barrel. Well good luck
