Hey guys I can't seem to find it answers with the search. I have a AR10 that i have been reloading rounds for they won't fully load in the action the bolt stops about 3/4 of the way then it's a pain to try and eject the unspent round. They are full length sized and twice fired brass. I can usually get one out of every 5 or 6 to fully load and fire off but that's not good odds at all, am I doing something wrong. Any help would be great thank you for your time.
