I only tried 2mags with multiple rounds in them and both times the bolt didnt lock back...I did adjust the gas to the full open position(20) between the two mags. The condition/ overpressure sign on the shells seemed to be reduced to mild flattening of the primers on the Lapua ammo and mild cratering of the M118 with one popped primer. No ejector swipe to speak of.
Sorry about the delay in response - the forum didn't show your post as new to me.

In my experience: Getting too much gas into the system can sometimes cause failure to lock back on a mag with a single round. Exacerbating the issue, some AGBs have steps that are too big, and you can step from undergassed to overgassed very quickly. I've found that using a continuous infinitely adjustable gas block is better than a detent-based system in large frame ARs, because they're much more gas-sensitive than small frames.
