Before, long bullets would reach over the extension and touch the vertical portion of the breech face, just below the chamfer. If I seated the bullets deeper, the shoulder of the case would contact the extension and lift the tip of the bullet, and it would feed fine. The alteration was pretty easy, and I just cut two wider angles on the existing chamfer(going no deeper), and blended them. My gun never had issues with the factory creed barrel. This barrel is a 6.5x47, and showed the issue immediately. I’ll see if I can take an after pic.
