I'm very confused as to the behavior you're describing. Are you having trouble extracting _unfired_ rounds without mortaring, or are your fired rounds not extracting without mortaring?
The first problem is a chamber issue - rough or maybe dimensional. The second problem is a gas system issue - probably a loose gas block.
I'm having a problem fireing unfired rounds, BUT.. only AFTER firing a round. IE.. if i take said live rounds, lock the BCG back, and feed a round it'll extract fine. If i fire that round (or another one) it'll cycle (eject and feed another round). THis is where the problem starts though. Once it feeds a round after a previous one having been fired.. i have to mortar it.
This is behaving VERY much like a 223 wylde chamber that was head-spaced wrong from manufacture and blew up on me back in december... i dont want that w/ a 458 (or anything.. ever.. again)
