I can’t imagine that keyholing like that would be even be slightly tolerated and it’s not too difficult to get stable flight unless there are serious issues with the firearms.
If a bullet is tumbling out of the barrels, those barrels are seriously fucked. They are shot out, are using bullets that are too small or there are serious defects with the bullets.
A bad twist rate or extremely poor load generally won’t cause tumbling until much later. If the bullets start at slightly at supersonic and slow to subsonic quickly, that might do it.
I would like to see those videos of the keyholing you described, which is why my brain seems to have vomited all over this comment. (This has got me super curious, is all.)
That is a photoshopped picture, btw.
