Acceptable accuracy, but for me the contours are a bit heavy. I had a 6.5x55 made up on a Mark X action using an A&B barrel, had to have the barrel turned down as the rifle came in at 8lbs even before I put a scope on it. After turning, the rifle would group approx 1" no matter what factory load I put through it. I ended up selling the rifle because it was the least accurate 6.5x55 I had!
