I understand a slow twist not making heavy stable enough but not the other way around....

My experience is that over-spun light bullets tend to shoot inaccurately, especial if low quality. I guess it's a bit like a badly balanced turbo...

I am sure 55 gr will still work fine at normal combat distances but you want the extra weight of the 62-77 gr at longer distances anyway.

I remember that the steyr had plenty of problems when new including breaking firing mechanisms.
