George Mitchell passed away last year (shooter with the 100# rifle) so he's out of the mix. I like to use equipment made by shooters who use what they make successfuly. Neil Eddington is my current go to guy. He makes Legacy barrels and shoots them as well, check the record books at Friendship. He's not cheap and the wait my be fairly long, depending on what he is cutting, but it would be worth the time and money. Second choice is Ed Rayl in Gasway, West Virginia. Second only because his wait is even longer than Neil's.
