>9mm is too small

What's an actual good pistol cartridge?
Just lol if you defend your home with anything other than Mark II 12 mm rocket
>let's say 2,520 m/s
Internet says .177 pellets weigh between 6.5 and 8 grains, let's assume 8 grains which is equivalent to .0005 kgs.
A .0005 kg object flying at 2,520 m/s carries a force of 1.26 kg/m
For reference a 116 grain 9mm carries a force of 2.63 kg/m going by the same equation.
You probably won't get disintegrated.
This is all assuming I remembered my highschool accelerated physics class correctly.
so basically it would be like getting hit with a smaller caliber round, like a .22 long
something about that seems wrong to me, but I'll be the first to admit ballistics is a fickle bitch that I don't understand even slightly.
Not him, but the assumption that the best choices come from agencies and militaries has always bothered me. In alot of cases, "armchair [occupation]'s" really do make choices that are arguably better for their intended purpose. That is to say, someone who is supplying their own gear for their own reasons is usually going to make the best decision for their given situation. They are concerned with logistics on a large scale, cost comes down to personal preference, etc. You aren't having to worry about trainability, large scale availability, familiarity, and so on because its just for you.
Ultimately agencies and militaries are going to decide on what they feel fits their needs best. That list of needs happens to include quite a bit more things that your average person, so you can't really look at what they are doing and assume it's the best
The massive power difference between .45 and 9mm everyone pretends exist? I get larger variances in my rifle rounds by adjusting the powder charge a few grains.
Those two calibers and everything inbetween can do the same shit. What matters more is the actual bullet design
Women and faggots were complaining about recoil in full sized duty pistols in .40.
At least one major departments choice for duty ammo routinely overpenetrated and under expanded. Their fault, but still.
That's generally a bad thing for self defense ammo to penetrate obstacles because you will have unintended casualties, and you shouldn't be taking pot shots at people through walls or crap like that anyway
The thing about ballistics gel tests is that they don't translate to what a round does in an actual human body, nor does that show how it behaves with many common hinderences of an actual gunfight. This assumes that it's hitting 12" of skin and muscle, it doesn't account for stuff like bones, clothing, internal organs like the stomach, intestines, lungs, etc.
At one second, at the muzzle, the acceleration of a .177 (.0005kg) pellet flying at 2520 m/s would be 2520 m/s^2 and would have a force of 1.26 newtons
A .145 kg baseball being thrown at 105 mph (47 m/s) at one second directly after the pitch would have an acceleration of 47m/s^2 and would carry a force of 6.81 newtons
So according to my slipshod calculations, it's not that big of a deal but will probably penetrate because of it's very small surface area. I don't think you will be disintegrated though. It's just not enough mass.
Like I said, I'm going off old highschool physics. Hell if I actually know what I'm talking about.
I trust your data more than my own at least.
Most people don't have a foot thick torso. Five inches of right angle penetration will reach any organ in the path. The penetration standard does attempt to account for events such as hitting bone, thick clothes, a thin barrier, an arm or weapon before hitting the abdomen.
>not defending your house with one of these on the roof.
I came up with a quick way to get joules from freedom units (grains & f/s).
To compare, a 7.62x39 is 2200, 5.56 is 1700ish, 5.45 is 1300, 9mm is 500ish.
This means it's lethal but penetration is probably low.
>fired my Glock 20
>missed the embankment
>this was the next county over on the news that night
based on a barrel length of 2m and the given velocity of 2520m/s. Plugged those into
which was simplified from
v^2 = iv^2 + 2as
which comes out to
Like I said, been out of school for 8 years so im just spitballing.
You failed so horribly... BTW what you should be looking for is energy.
That little pellet would be pushing 1588J of energy... That is a shit load of energy in a very small place. my guess is that it cause explosive results on whatever is in the way.
That amount of energy is the same as what rifle calibers such as .223 produce. Don't let that fool you into believing that they would react the same on impact. I believe that the .177 would be far more destructive to a smaller area that the .223. In other words low penetration but a big ass crater.
No, enough to perfect your sternum before shredding your thoracic cavity. The energy delivery is on par with a 223/5.56 round.
Nuclear fusion between random atoms need speed like 90% light speed.
I don't know about that but, assuming that you use a regular lead pellet I think it would essentially "explode" and you would only recover sand size particles or lead dust from the pellet.
I'm not talking fusion or fission, though. No atoms are splitting or fusing, just molecules. You know, like in a normal explosion?
Because otherwise it's not going to "crater" you; it's going to have a normal bullet-hole style entry with a potentially messier exit on the other side.
>i've found it
>the perfect assassination caliber
>What's an actual good pistol cartridge?
there literally aren't any, every single pistol cartridge is underpowered and under performs in ballistics test.
They all suck at killing people.
The best defence isn't the caliber you own it's knowing how to use it properly i.e. mag dumping on the center of mass as quickly as humanly possible.
The .177 pellet would be atomized if it went light speed and probably would reach you if your more than 100ft away.
Assuming its made from something that could survive the friction of the air its passing through it would pass through you so fast its retarded, not pink mist you.
welcome to bureaucracy, son. my mom worked in the US army's department of munitions in the 70s; shit was hella stratified, apparently. Definitely operated on a "if it ain't broke, don't fix it" mentality.
anything with mass going the speed of light would instantly turn into a nuclear explosion , since you're basically fusing anything the bullet "passes through" with the bullet. XKCD what if has an article about this , but I wont bother linking since for some reason 4chan dislikes the author , and some will probably call me a faggot just for mentioning him.
I don't agree with this theory, regardless of what the pellet is made out of it will very quickly and violently displace a lot of material. All one has to do is look at how water reacts when getting shot. It doesn't just zip cleanly into the water at high velocity, it violently makes a huge cavity where it strikes.
The higher the velocity, the higher the hydrostatic pressure upon impact and therefore more explosive results.
Okay, going with what I know and understand an 8 grain pellet traveling at 8276 fps will generate 1214 ft lbs of muzzle energy, about equal to hot .44 Magnum from a handgun or 5.56 from a 16" barrel in a much smaller area.
Something that small moving that fast will have to made of something pretty hard, at least brass or maybe steel or it will disintegrate leaving the barrel. It's be a great penetrator, but would likely punch neat holes in flesh unless it hit bone.
Shoot a watermelon with a subsonic .22 then shoot it with a .223. By your theory the ,223 will make a cleaner hole. But we both know that's not true. Go ahead a repeat it with a steel core bullet, and you will still have a mess.
Yeah, but the flesh of the melon is more rigid than human flesh. It'll react differently to the shock wave than animal tissue. By the same point, fmj .223 tends to punch neat holes in flesh as well. Soft tip .223 is a whole other story.
I want 10mm auto Magnum chambered in one of the new aluminum framed Deagles.
>double stacked 15 to 18 round five inch 3 lb Desert Eagle equivalent to .41 Magnum
I know this is a troll reply, but gold has similar weight and malleability to lead. It'd work just fine, but not be "better".
Tungsten, depleted uranium, or sometimes steel with Teflon coating are all great, especially for AP and barrier penetration.
Those are all illegal for civilian use in most states, and maybe some Geneva shit applies too.
.357 Magnum is hands down the best pistol cartridge.
Now if we could make an unrimmed version it would quickly popularize and be used over every current popular (see: subpar) cartridge available.
I love the shit out of .357 and think its amazing, but not even I believe everybody would just adopt a cartridge like that overnight. .357 Sig isn't really going anywhere good either.
I was being facetious about adoption of course. .357 Mag is, in my opinion, ballistically superior to handgun cartridges that people typically carry.
.357 Sig is just too damn expensive. And with so many cops going away from .40 and .357 Sig back to 9mm it doesn't seem like widespread use will ever happen.
I think 9mm is basically entrenched as the standard carry round. It's small enough to have good capacity, still has deep penetration, and is very common to begin with.
Money reasons...less lead and brass, less pennies. 9mm is for Jew budget managers of large federal agencies.
Meanwhile small organizations like the Air Marshals use .357 Sig because it's so expensive to pad their operational budget. The Air Marshall have been known to realize their job is not that important and just view it as traveling across the country and drink hard and party on the tax payers dime.
You'd think a high penetration round would be a bad choice for inside an aircraft...forget depressurization, just over penetrating the perp/terrorist suspect and then going through a few innocents sitting a few rows forward or a stewardess or hitting the pilot.
Since most people on planes don't wear armor, even the non military only 5.7x28 would be a good option for accurate pin point shots in a possible hostage/human shield situation and not damage the plane or kill other crew or passengers.
>The Union had enough industry to have all the fancy rifles and lever actions that they wanted
on paper yes, realistically the production time and logistics prevented a lot of Union soldiers from ever getting their hands on the significantly improved firepower available to them.
You also forget that much of the Confederacy was built and funded on the backs of an aristocratic upper class that could provide themselves technologically superior weapons, if not simply build them.
Your average joe confederate was poor as dirt though
"Properly designed hollow-point ammunition - regardless of caliber - all perform very close to each other when you take expanded diameter and penetration depth into account"
>1500-1900 fps with various loads and barrel lengths, pistol/carbine
>bullet weight similar to 45 acp
>can penetrate body armor at close range and has similar ballistics to 5.56
What more can you ask for? This is my favorite pistol round besides .357 magnum
The five-seven shoots rifle style bullets.
You're both wrong.
1.26N~=punch from grade school kid
pressure cuts holes in shit
1.26N/.02025m^2 = 62kg/cm
This will obviously hurt like fuck and punch a hole approximately .177" in diameter. It won't go through bone, as bone is capable of much better pressure resistance, bit your soft tissue is fucked.
You now know.
>Comparable bullet mass to .45 ACP
Try 60 grains less at minimum, Anon.
7.62x25 is soviet .357 SIG. It goes fast and penetrates like the dickens. Unless you load JHPs because you don't want to shoot through the mugger, the wall behind him and the brainpan of the clerk beyond that... in which case it will sometimes expand to the diameter of .45 ball and sometimes not lose the jacket in the process.
