Since no one touched on the point of your chambering a round problem, I will put my two cents in here. With my 223 I can only neck size 5 or6 times before the cases are hard to chamber, so I full sized every 5. Now I neck and body size with 2k shoulder bump. Hope it helps, by the way, 1/2 inchers are pretty outstanding from a hunting rig, sounds like a keeper!
