I saw a video a couple of weeks ago released by the Chinese military where their soldiers were shooting at targets. Looked like a standard military drill video until someone pointed out that all the shot placements on the targets had "keyhole" shapes where the placement was a slit instead of a round hole Which means, the bullet wasn't travelling in a straight line and tumbled through the air which makes it more likely to miss it's mark and leads to malfunctions in action.
Between Japan and China when it comes to technology, Japan is whooping China all day every day. Their manufacturing capabilities are renowned for quality while the Chinese are out here putting out guns that can't even shoot straight
Not surprising when you remember China routinely manufactures cheap crap, have people who fall through elevators, have people eaten by escalators, have shyt they launch into space fall back to earth uncontrolled, etc..
I'll have to find that video.
Edit : here it is. Also notice it's doing this while they are right on the target. They are doing that because they would fukking miss if they were any further
