Is it common for the extractor to not retract when chambering a round, stopping the bolt from closing? I think I'm having a problem with that. Once in maybe 5 to 10 rounds, the bolt will not close. I've tried 5 rounds, cycled through the chamber continuously. sometimes it closes on all the rounds and sometimes it will hang up on one of them. It's random and it doesn't isolate itself to a single round.

Never hangs up with an empty chamber. Headspace is good to go. I checked with a PTG GO gauge.
