When I first headspaced my new 22-250 barrel, I apparently set it a bit too close. Although factory ammo would fit fine, my RCBS FL die would bottom out on the shell holder and not bump the shoulder back once my brass hit that stiff bolt closure max dimension. So after pondering my options, I loosened the barrel nut and backed the barrel off a few thou. Problem solved, everything fits and works like it should and I can get a good .0015 to .002 bump.
