The problem I'm having is the the bolt begins to feed the round, but doesn't quite seat all the way to full battery. When you cycle the action to remove the failed round and feed a new one, the round is bent with scrape marks on one side, and no indent on the primer. I also have two HK mags, and only had a couple problems with feeding on these mags.
ps. on the second range trip i did clean and re-lube around 100 rounds.
