The standard “ball” bullet used by the Russian military, at least, in the 5.45x39mm is designed to easily tumble once it is inside the target. It is more of an effect of the bullet’s construction and fine tuning of the rifling twist rate than the caliber itself. But it is still supposed to remain stable with the nose pointed forward when traveling to the target. Otherwise it becomes extremely inaccurate and loses its velocity very rapidly, which causes it to fall short.

It is keyholing. It happens when as you can see the bullet loses stability and tumbles in the air before hitting the paper sideways. It can be caused by many things. Insufficient rifling twist for the length of the bullet being used is one of them. The bullet hitting the ground or something else before hitting the target is another possibility.

Either way, it isn’t a desirable thing and indicates that something is wrong. The fact that the PLA members are proudly posting pictures of a bunch of keyholes randomly splattered all over a target like that suggests that they think this is normal and that therefore they don’t know what they’re doing.

The term “keyholing” is also sometimes erroneously used to refer to when two bullet holes are touching on paper.

If they are to drive an armored vehicle on public roads during peace time, even the military necessitates a vehicle commander standing out of his hatch with direct communications with the driver so he can have an overview of what’s around the vehicle and compensate for the driver’s blind spots. It is a basic safety rule.

9Gag is pretty bad with them as well. They used to push anti-vax and anti-mask disinformation with obvious bad faith arguments there during the COVID period. Then when the “special military operation” started in Ukraine they immediately switched to posting pro-Russia bullshit.

Until then I was only thinking this sort of nonsense was there as a result of the website being more open to diverse political views, for better or worse. But that sudden switch made me realize that it was actually a team of people trying to sow the seeds of disarray in any way they could for the Western world by pushing disinformation like this on websites mostly frequented by young adult males, who can be vulnerable to radicalization. To think back to it, it was obvious that they were using a bot farm to upvote their content as well. I haven’t set foot on that echo chamber or propaganda and conspiracy nonsense since then. I can only assume this sort of thing is still going on there.

I laughed at the APFSDS one.
