The loads it short stroked on were admittedly handloads that are a little on the lighter side but they are also by no means squibs either. The first three didn't cycle/feed then the rest of the mag fed fine. I made sure with with some follow-up mags of Prvi M193 and they also cycled fine.
I think omd posted about an alternate gas regulator in the works that has two "S" settings, a high and low, so maybe this is something that is being addressed. I like being able to limit the flow of gas while suppressed so the rifle doesn't beat itself up so we'll see what shakes loose.
