Try a 30-06 case seperation on a huge ten point, squeesed off a round, sounded funny, didnt think to much about it at the time, autoloader, buc stood there, went to squeese off second round, nothing happened, buc just standing there. Slowly I pulled the bolt back to chamber another round, bolt went part way and stopped, tried a little presure, wouldnt budge, looked at it and found part of the case was still in the chamber, big time jammed. I had to watch one of those once in a lifetime bucs feed for about ten minutes and slowly walk off!. That happens when you try to get too much use out of your brass.
