Regardless of their shape, the issue is that bullets are being used to perpetuate white genocide in South Africa, along with depleted uranium, crossbows, deepfakes, hot sauce, and anything else that can be used to murder or humiliate white people. By debating the shape lf the bullets, not only are you putting the spotlight on only one of these weapons, but you are ignoring their use in white genocide. This will not stand.
I'm not from the 'states so I don't know that much about guns, but wouldn't this cause the powder detonation to stress the casing in uneven ways, and thus be much harder to manufacture safely? As opposed to a cylindrical design where the force would be distributed evenly on the cross section?
Now I'm just a simple country physics 101 student, but this here mathematical hypothesis seems plausible to me.
they don't know bout my hex ammo
THE SQUARE BULLET HOLE MURDERS
ACKSHUALLY
It's the casing that's square, the bullet itself is still round..
I've heard of triangular ammo used in a mag fed revolver.
Basically the cons of weird ammo shapes are cost of manufacturing vs very little advantages.
Only advantage I can see here is it would pack up a little neater in a box/ammo can.
Isn't the ideal packing shape a cylinder? Specifically for rigidity and use of space.
I'm not a Geometrist but I think hexagons beat cylinders space-wise by just a bit, but again you hit the cost effectiveness curve and cylinders win.
hexagons leave less empty space between objects because they have extra material sticking out, but that extra material also means they have to sit further away from the sides of the container
circles already pack in a hexagonal pattern anyway so you're not gaining any stability either
Rigidity is the big thing anyways, anything with corners has failure points. Plus the small amount of space around cylinders can be used for packing material.
I assume that this could work but has literally no advantages over just making it round and therefore there is no reason to do it
You can put round ammo in at any angle, these would need to be square on and if they deformed during ejection you'd have a nasty jam.
Also much easier to turn a round punch than mill a square one.
Not as much. Rifles have spiral grooves on the inside of the barrel, which impart a spin to the fired bullet to improve its stability and accuracy. Without a spin a fired bullet would not be nearly as accurate.
That has nothing to do with the shape of the casing, which never travels through the barrel. The bullet itself is still round in this picture.
Also, you could totally rifle a barrel to impart a spin on a square (or any polygon) prism bullet, just needs slightly more precise helical indents. Possibly you might be able to impart spin on the bullet more effectively than a round one.
It might spin more but it would bleed velocity much faster
That's interesting. I don't have any kind of engineering background and not sure what to Google. Are there examples of this?
I probably should have looked at the picture more closely huh 
Well sure but the bullet isn't square just the shell. The shell stays in the chamber
During the age of sail some navies experimented with square shot because they thought it might be easier to manage them on a rolling ship. But it turned out that making the bore for the cannon square was way harder than just stacking round shot carefully the way they had always done
Cartridge alignment is one less concern when you're stuffing the cylinder into the round hole?
