A .32 bullet bottlenecked into a 9mm casing that has a .30 meplat that weighs between 80 grains to 100 grains that travels at 1600fps minimum, preferably at 1800fps if possible from a 4inch barrel.The wide .30 meplat would take advantage of cavitation at high speed. And since its a lightweight bullet little muzzle flip occurs.
>>62777594>cavitation at high speedi also like to repeat cool sounding words without understanding what they mean
meplat this dick
>>62777617What's cavitation? And what's fps?
>>62777662CAVITATIONNO PUMPINGfps is first person shooter, like call of duty or rocket league
>>62777594To have sufficient frontal area for meaningful TSC at those velocities you'd need an expanding design, a flat nose wouldn't cut it. Doable with a solid copper HP, doubletap has some similar projectiles in 9mm for use with 9x25 dillon for example. Also at 1600fps it'd be iffy just how meaningful that'd be, but up at 1800fps it definitely would be. I think your big hurtles would be getting those velocities with reasonable pressures and stresses on the gun(durability concerns), not an internal ballistics guy though. Sooner or later somebody will make something like this, and i've considered it a bit myself, the support is there for it on the terminal ballistics side of things. I imagine even once somebody manages to make such a cartridge it'll end up flopping though. It wont be cheap, itll have a lot of blast, the recoil will be on the top end of whats tolerable for most shooters used to 9mm recoil levels. Agencies wont want it because it'll perform poorly through intermediate barriers and the dunning-kruger types whos knowledge of terminal ballistics begins and ends with a couple cuckygunner videos they've watched will shout it down as snake oil. Doubt it'd catch on.
>>62777594>.32 bulletPhone up Federal and ask them, theyre on a roll with .327 mag and .30 pooper carry
>>62777667So what does 1600 fps mean? Frames per second?
>>62777681fps is first person shooter. i like how the post you replied to said this and you still have to ask again.
>>62777594Congratulations you invented .30 Luger +P 110 years later.

>>62777672>.327 maga quick search, but this looks close to OPs specs. No idea how it actually performs.

>>62777698that would be very hot for magnum tokarev
>>62777705>had to look up .327 mag
ok how about this ammo concept: it's a light gas gun but self contained in a cartridge. the powder charge shoots a piston inside the case which compresses gas until it builds up enough pressure to shoot the bullet out at a billion fps.
>>62777756I was looking for the hottest 327 I could find. Point being somebody might already make something with similar ballistics to ops cartridge from a longer barrel (.327 lever gun etc.). Then we could see if it actually gives any answers to the "cavitation" question.
my asshole cavitates when i eat indian food
>>62777787Henry makes a .327 lever gun idk about any others
>>62777594No I have a better idea a .69 caliber bullet traveling at 4200 FPS with zero recoil
>>62777594I have a better idea just shoot liberty civil defense 9mm out of your 9mm gun that you already have for the same results
I wonder how many "9mm killers" I'll see come and go in one lifetime
I did the math pic related. I averaged the muzzle energy of all sig .357 ammunition from underwood and I got 583ft/lbs as the average. That means that so long as the ammo doesn't go above that it should generally be safe, and I know the ballistic coefficient of 9mm is 1.40 on the g1 scale and I know that flat nose bullets have less ballistic coefficient...I assumed it would have a 1.20 BC because it is shorter, I ignored the fact that since it becomes thinner in diameter jumping from .354/9m to .32 in diameter that it should gain BC. So I only put it into the calculator as the worse BC possible. I think this would be a pretty great bullet design seeing as how fast it is at 10 yards and 25 yards and 40 yards.I know bullet cavitation starts to noticeably occur at 1300fps, so the fact that it can reach nearly 1300fps at 100 yards means it can still induce super cavitation for several inches into ballistic gelatin at 100 yards.I wish I had the money to design the bullet and then make a version which has a flat nose plastic ballistic tip which would obviously be several grains lighter since the polymer ballistic tip replaces some of the lead within the bullet, it would probably weigh 70 grains or 65 grains and go 1850fps instead of 1800, but that type could be used as a varmint bullet or a low penetrating fragmentation bullet
>>62780524Or maybe none of the weight could be lost and instead the flat nose is completely replace by a ballistic tip that isn't flat, just a chemically bonded polymer tip directly on top of the flat nose so it could still maintain a weight of 80 grains therefore maintaining penetration
>>62780531What if they added fish hooks to bullets too? It would catch on so much shit and hurt lmao.
>>62777594There's a lot of problems with your idea due to some incorrect assumptions.>.30 meplat>weighs between 80gr to 100grWhy not just use a 9mm 90gr flat nose FMJ? You don't have to design some weird .312 bullet or even a new case.>1600fps minimumThat's all you'll get. Grizzly loads their 90gr loads hotter than even Buffalo Bore would dare, and they just barely get 1625 out of a 5" barrel. That's without the inherent loss of acceleration you get from bottlenecking a cartridge with a similar weight bullet.>The wide .30 meplat would take advantage of cavitation at high speedFlat nose really doesn't cavitate very well until you get over 2000 fps. From my own testing, 135gr 10mm moving around 1600 fps with a similar meplat still penetrates well over 36" in gel, meaning it's not putting out a lot of radial energy dispersion. With a 115gr flat nose going 2200 fps out of a .350 Legend, I did see 21" of penetration, which indicates a cavitation effect, but the tip mushroomed out to about .40 caliber, so a .30 meplat is right out at lower speeds.Your heart's in the right place, but you're trying to get blood from a stone with those target numbers, and the assumed wounding mechanic won't work well anyway if you could.
>>62777720So a third world mutt land without universal free healthcare? Got it.

stop pretending you know what it'll do and make it. nobody is impressed with talk.
>>62780933You just talked, nobody is impressed. Prove it
>>62780894>Why not just use a 9mm 90gr flat nose FMJ?.32 caliber 80gr bottleneck = less muzzle flip, less malfunctions, more barrel area for more recoil reduction, lighter overall weight, higher ballistic coefficient due to reduced diameter, can be used in a p90 variant due to bottleneck, can be used in a 6 to 7 round 3 inch barrel single stack pocket carry pistol reaching speeds in excess of 1500fps>inherent loss of accelerationIts the opposite>Flat nose really doesn't cavitate very well until you get over 2000 fpsThen why does the us army now use 1330fps flat nose ammo that leaves a cavitation trail? 1300fps clearly cavitates if the us army uses it.You need to study this more.
>>62781496>You need to study this more.>t. appeals to authority.
>>62777594"high speed" only has an effect on terminal performance for very specific fluted projectiles, for most "high speed" only has an impact on terminal performance/lethality as a component of projectile energybraindead 5.56cels keep telling themselves retarded things and make things even more retarded as a resultthis still inferior to 9x25 dillon anyway https://en.wikipedia.org/wiki/9%C3%9725mm_Dillon
>>62783303this is still*
>>62783303I want a 9x25 dillon rifle with 10" barrel
>>62777594why the fuck would you use the most obscure handgun possible to show this
>>62783555hardly, I have one (it's great even though it's in garbage 9mm)
>>62777594Bro that's basically .30 carbine from a 9mm case.A pretty big ask...I wish they'd introduce rifle level pressures into pistols.
This is for Euros who can't use military calibers.
>>62783603What if we just made handguns with cased telescoping cartridges? The Textron NGSW 6.8mm was almost short enough to fit in a handgun grip.
>>62783633>>62783603There's a limited amount of power a handgun can realistically handle due to recoil, weight, etc. Cased telescoped cartridges would be very interesting in a handgun or PDW, however. What's most interesting to me about the idea is being able to easily feed cartridges with spitzer bullets without long bolts or cases. Imagine a CT cartridge with a .308-sized hollow point spitzer bullet with enough powder for ~650-700 foot-lbs of muzzle energy.
>>62783401make one. I don't know why people think it's impossible to do stuff like this. you could probably make just about any 10mm gun into a Dillon without having to modify a magazine. just have a custom barrel made and install it. maybe you have to fudge with the feed ramp, but I doubt it, you are going to a more pointed cartridge. aren't there AR pattern 10mm? get a shop to just ream a 9mm barrel chamber to Dillon, bingo, bango. though I don't know why you wouldn't go to a real cartridge if you are putting a 10" barrel on it. it'd get dunked on by something like 350L>>62783758>Cased telescoped cartridges would be very interesting at reducing handgun capacity, the thing they already struggle with and ruin feeding through even blunter and more rebellious geometry.
>>62783303>>62784095No thanks bro, your take back of Dillon is cool and all but a g19 proportioned dillin can only hold 13 rounds, plus the recoil would be immensely high, plus the Dillon requires 6 inches of barrel length to reach those impressive speeds. No one is going to carry a 10 inch overall length handgun as concealed carry or open carry duebto length. Also the chamber portion of the barrel will now have to become thicker to handle the higher pressures which means for safety reasons the barrel itself increase in diameter slightly, also the Dillon is round nosed by default meaning it can never induce cavitation because for cavitation to occur you need a flat nosed surface.Plus have you ever considered how wide a gun with Dillon would be, it would be as thick as any .40 cal handgun, people don't want that, it would be impossible to reach a true 1 inch wide thickness of a carry gun. That means no more pocket carry and no more shorts short carry if you are under 6ft.I still think my idea is great since it retains compactness and high speed, tye Dillon is great except for the fact it is too wide and you can't carry 1 inch wide handguns chamered in it unless you go the 6 round single stack route with it. But then you have something like the diamondback gen 4 in 9mm and in a single stack magazine it can only carry 6 rounds max, so in a single stack .40 cal with the same dimensions as the diamondback gen 4 it would only carry 5 rounds.
>>62780913>Me me arrows that he's controlled by savage retardsDamn guess you niggers are just soft pussy pushovers or even bigger retards
>>62784482To sum it up>A 6 inch barrel is required to justify its usage>Dillon won't reach highspeeds from a 4 inch barrel>Dillon isn't flat nose, making cavitation impossible>Lower ballistic coefficient>Weighs more over all>10mm casing is too wide>Goodbye 1 inch width guns with DillonThe bullet is so damn heavy and going so fast that a compensator is needed to shoot it accurately in competition according to competition shooters who have used it.My idea of a bottlenecked .32 with .30 meplat in a 9mm casing weighing between 80 to 100 grains is better. It's BC is high, it can be shot from a 4 inch barrel between 1600 to 1800fps. Because of how light it is it has lower recoil. Because of the decrease in diameter the amount of total metal in the barrel is increased because the barrel diameter is smaller if using a default 9mm barrel. It would still travel 1300fps at 100 yards because of its ballistic coefficient. It can reach its high velocity from a 4 inch barrel meaning it can be concealed carry.
>>62784595honestly, your post is stupid and you should be killed
>>62777594Hear me out. A 1 grain bullet that travels at relativistic speeds
>>62784696We're not there yet.
>>62784729>ME1kek based
>>62784692You're stupid. You need a minimum of a 6 inch barrel with a compensator to even compete in competition with Dillon just to manage the muzzle flip. A g19 has a 4 inch barrel and is nearly 7 inches long in overall length. Now let's say it can chambered Dillon, you'd have to make the barrel 6 inches long at minimum. Now its overall length is 9 inches long, then you'd have to add a compensator to it which tend to be 1 inches long, now you have a 10 inch long overall length handgun just to handle muzzle flip. Let's not forget that the 10mm casing is even longer than the 9mm casing, by a quarter inches. Add to that the chamber has to be made longer to compensate for this and the now you definitely have a a 10 inch long handgun for competition use
>>62784791please post proof you have a gun
>>62784696what does the effect on target look like? im going to need some harrel watermelon hog tests
>>62784791It would 3 inches longer than a g19 and significantly heavier. Meaning drawing it from your hip would take slightly longer on average, do you know how front heavy a gun like that would be, imagine have half a second to get your sights on the center of a target with a gun that front heavy. Its crazy, and thats why nobody uses it anymore, plus few use 10mm cases so it has to be expensive, but everybody uses 9mm cases so my idea of a .32 9mm bottle neck is significantly cheaper than dillon
>>62784795Can forget that the breach has to be made thicker in width and length to handle the Dillon, so now you definitely have a handgun that is 10 inches long. Get a ruler and cut down a branch to 10 inches, it would get tiring carrying something like that everyday for patrol
>>62784813tell you what, you don't have any guns whatsoever, but if you want you can make a gun for your fake cartridge and give it to me so i can shoot you with it
>>62777594Holy SHIT anon, nobody has EVER thought of that before. You better get to the patent office right away. Fucking revolutionary.
>>62777594temporary cavity doesn't do shit outside of the liver or brain (so only the liver)you want fragmentation if you want a large wound cavity.
>>62784905None of those rounds reach 1700fps from a FOUR INCH BARREL and none of them have a .30 MEPLAT and none of them are .32 IN DIAMETER. They all have worst ballistic coefficients than a fast flying .32 and none of them reach 1300fps from 100 yards away.
>>62783758>realistically handle due to recoil, weightChamber pressure =/= recoilA pistol that can handle 60k psi doesn't have to be too heavy either
>>62785136>None of those rounds reach 1700fps from a FOUR INCH BARRELLiterally zero advantage over any of the light fast 9mm meme bullets. >none of them have a .30 MEPLATYou don't understand wound ballistics, see >>62784954You know anon, I was like you once. Posting shitty threads about my dumb gun ideas. I can't fault you since the best way of getting good info here is to write nonsense and get corrected. So, keep it up I guess.
>>62785241>Literally zero advantage over any of the light fast 9mm meme bullets.>Literally zero advantage>zero advantage>zeroBruh, how can you say that an increase in nearly 550fps holds no ballistic advantage whatsoever, even the army uses 1320fps flat nose 9mm. https://www.ammunitiontogo.com/750rds-9mm-winchester-active-duty-115gr-fmj-m1152-ammohttps://youtu.be/0vR07Ux6wRk?si=WI-h2NXmjndPfOE9
>>62777594Very interesting. I think that it may duplicate 7.62x25mm Tokarev in a different form and, now, my personal conspiracy theory is that the Soviets in the 1930 have surely chosen this cartridge after _extensive_ testing on "live targets" - so to speak. It's probably very effective (they later replaced it with 9x18 just because they went for a small and light package in their backup weapons)
>>62785367>appeal to authority this isn't an argument, nor is your inability to know that you can just stick a different projectile in almost any caliber to change its terminal performance. post gunand before you make a post ignoring this one, post gun. you have no idea what you are talking about.
>>62785367The Army uses flat nose because they have to. There's no reason not to use a minimally expanding JHP like Critical Duty if you have the option to do so.
>>62785860>The Army uses flat nose because they have to.They don't use flat nose because they have to, they use it because they want to and because its beneficial, in some ballistic gelatin videos you can clearly see it tears apart gelatonin because of it.
