Author’s note: So if anybody wants to know why this shit took so long, it’s because I could not, for the life of me, find real world cases of uses of 5.7x28mm on shit that actually BREATHES. I had to hunt high and low for that information.
And I got it all together on September 9th, 2025.
And then the next day shit went down. Charlie Kirk was fucking murdered, and I……Really wasn’t in the mood to write graphic descriptions of what bullets do to meat and bone after seeing somebody I really respected getting killed that way. It just….I dunno, I couldn’t. Every time I sat down to do this, those images were in my brain and I felt like was gonna throw the fuck up.
So I needed some time off. But we’re back, and we’re mulching Fluffies with high velocity pistol rounds this time! Gotta say, it wasn’t easy finding the data I use to make these, but it was fun as shit once I did and once I was in the right headspace. For anybody who’s not heard of this little pocket-rocket of a bullet, it’s a hell of a little round, basically a .22 magnum rifle in pistol format, with better reliability and moderately more wounding.
That’s enough of my prattling. Do enjoy!
Part 3:
5.7x28mm
Firearm used: Ruger 5.7.
Barrel Length: 4.94 inches.
Bullet used: SS197SR “Blue Tip” V-Max bullets
Bullet Weight: 40 Grains.
Test group composition: 1 Adult Mare, Pregnant (Immobile). 1 Adult Stallion. 3 Chirpies sourced from other fluffy group. (Adults were summarily euthanized for uncooperative behavior.)
Results:
Researcher Carlisle enters the room, and racks the slide, before discharging the pistol into the stallion at a range of 10 feet. The male immediately collapses with an exit wound roughly the size of a penny just to the right of his spinal column, and coughs out blood. The stallion is immediately killed, see necropsy for cause of death.
Researcher Carlisle swears and checks to make sure his hearing protection is in.
It is.
Thus having ensured his safety, Carlisle turns his attention to the mare.
“Speshul Fwiend? Why Spushul Fwiend faww ova? Woud Scawiest noisies, am bad for tummeh babbehs! Need Speshul Fwiend to push soon-mummah!”
Researcher Carlisle shoots the first of the chirpies, who are crying, defecating, and clutching at their ears from the same distance. The chirpie pops like a water balloon, spraying the mare, and it’s siblings, with blood, feces, bone fragments, and other assorted viscera.
“SCREEEE!!! BABBEH GO BOOM-BOOM!? SCAWY NOISIES MAKE BABBEH GO BOOM!? NO WISTEN TUMMEH BABBEHS, NO WISTEN TO SCAWIEST NOISIES!!!”
Apparently desiring to test something, Carlisle approaches one of the chirpies, places the muzzle next to it’s ear, and fires a shot into the floor.
“SQUEEEEEEEEEEEEEEEEEEE!!! SQUEEESQUEEEEEEEEE!”
The chripie urinates on itself, and clutches at it’s ears, blood can be seen discharged from the ear closest to the muzzle, and from the nose as well. Carlisle stands up, walks back, and headshots the other chirpie.
It’s head explodes immediately upon impact, spraying brain matter, underdeveloped eyeballs, teeth, and the bones of the skull on it’s now deafened sibling, and the pregnant female.
Researcher Simmons speaks over the intercome. “Hold up. Shoot her in the belly. See if the Hydrostatic shock kills the foals.”
Researcher Carlisle nods, and rolls the mare onto her back.
“Pwease! No Huwt tummeh babbehs! Nuuuu! Pwease, No make soon mummah into mummah no-mowe wif….Hi….dwo….sta…ick?”
Carlisle pauses for a moment, apparently surprised she managed to pronouce a word with that many syllables.
He shoots her in the stomach.
Upon impact a ripple can be seen in her belly, and the dam immediately vomits, defecates, and urinates. “WOWSTEST TUMMEH HUWTIES!!!”
The bullet expands, partially fragments, and yaws, coming to rest under the skin on the mare’s back, just behind the pelvic girdle.
“B-Babbehs? Tummeh babbehs!? Pwease….Pwease mobe tummeh babbehs…..Why soon-mummah no feew tummeh babbehs no mowe!? BABBEHS PWEASE MOBE FOW MUMMAH!!!”
The dam spasms.
“BIGGEST POOPIES!!!”
Researcher Carlisle takes several steps back.
The mare violently miscarries, spewing a mixture of blood, amniotic fluid, foal parts, and intact, severely bruised foal corpses.
“Holy shit….”
“You may now euthanize the female.”
Researcher Carlisle shoots the Mare through the bottom jaw, up into her skull. Her jaw breaks, and teeth are sprayed out, the top plate of her skull is violently broken, and a mixture of blood, brain matter, and cerebral fluid spray onto the wall behind her.
“I’m leaving the deaf one alive for an examination, then we can put it down, okay Simmons?”
“Good idea, bring it out here and we’ll get looking.”
Necropsy results:
The stallion’s wound is consistent with that of a .22 magnum hollow point, leaving a deep, wide wound channel relative to the bullet’s size. The bullet entered just to the right of the sternum, above the 4th rib. The round immediately began to expand and fragment, tearing the heart in two, ripping the paracardium, and causing a wound tract about 7.5mm in diameter to form as it went. Upon exiting, the bullet passed betwen the 5th and 6th rib, tearing a chunk of tissue about the diameter of an American penny, and leaving the body.
Bullet was recovered in an expanded state, and retained 94% of it’s pre-firing weight.
Noted is the level of remote wounding in the subject, with severe bruising in the surrounding tissue, including blood pooling and clotting in the lungs, ruptures in the muscle, and even burst blood vessels in the eyes of the subject. This is consistent with Hydrostatic Shock, where fluid is displaced so rapidly inside of a living thing that it causes ruptures in delicate tissue. This was fully expected with the testing of 5.7x28.
Mare’s cranial wound was, naturally, lethal, with the bullet passing through the soft palate, causing a hole in the tongue about 7.3mm wide, impacting the hard palate, breaking the bones, and continuing an upward trajectory while fragmenting explosively. The bone fragments, bullet fragments, and seperating jacket of the bullet acted as shrapnel, and created a very large amount of damage, with multiple wound tracts.
The top of the skull was blown apart, and bullet was largely unrevoverable, with only a few small pieces of lead, plastic, and copper being recovered. Weight was neglible.
The unborn foals were examined next. A total of 8 were found. Several of them were torn into pieces, apparently either having been in the direct path of the bullet, and thus mutilated directly by it, and were largely recovered in pieces.
Of note, however, is the fetuses not in the direct path of the round. These fetuses were heavily bruised, many with rupture eyes, organs, and some with blood running from their mouths, or even brain matter liquified and discharged from the nose, in one case.
It is believed that the amniotic fluids of the womb acted as a potent transferral agent for hydrostatic shock, and imparted it onto these unborn foals with extreme force, crushing organs and rupture blood vessels, veins, and arteries.
More research may need to be conducted into this as a method of both aborting foals, and killing the dams, at high speed, range, and low cost.
Foal examination results.
The deafened chirpie was immediately rinsed off with isopropyl alcohol, and examined. It’s eyes were forcibly opened, and it was determined that had been ruptured by the pressure of the muzzle blast. Endoscopes were inserted into the nose and ears.
The sinus cavity of the neonate foal were badly damaged, with multiple bruises, severe tissue inflammation, and broken blood vessels. The ear furthest from the shot was missing an eardrum, having apparently ruptured and torn away from the pressure.
The ear closest to the blast, while outwardly sound, was inwardly “Fucked”, in the words of Researcher Simmons. The drum was completely gone, the bones of the middle ear were embedded into the flesh, and the small hairs in the inner ear were blown away or broken.
Out of an abundance of curiosity, an endoscope was inserted into the foal’s GI tract. No abnormalities were found.
The foal was disposed of along with the rest of the subjects, being tossed into the biowaste incinerator.
Psychological notes:
It appears the high volume and severe damage of these rounds have a profound psychological effect on fluffies. The dam seemed to be unusually intelligent, capable of understanding the association between the sound of the firearm’s discharge, and the death of the other subjects. This should be noted as a point of caution, as she was a feral and thus other feral fluffies will be capable of this as well, on some level.
The abortion of the unborn foals seemed likely to be about to cause a “wan die” loop in the dam. This may be an effective method on the mates of fluffies. Additional research will be conducted at a later date.
Researcher notes:
“Holy shit. Can I keep this thing?”
“No, that was provided for testing and we have to return it.”
“Dammit, I like this gun. I want one. Why aren’t we using these for fluffy extermination?”
“Cost, mostly, the round is expensive.”
“I still want one.”
“Well they’re completely legal in Wyoming, so go buy one, they’re not that expensive relative to our salaries.”
NEXT TIME: 5.7x28 SS198LF, Maybe .32 ACP as well.
