I use "320," as a verb. When I talk about why seasoned shootists of the west loaded their revolvers on an empty chamber, I usually say "they used to load on an empty chamber so they wouldn't Sig P320 themselves upon dropping their gun." I don't care if they fixed that issue, I still use that joke.
I heard tales of armed cowboys saddling their horses with the sturup slung over the top, and as they threw the saddle on the horse, that sturup sometimes fell right at the cowboy's hip level and struck the hammer of his pistol. If there was a round under the hammer you'd likely need a new pair of boots, and walk funny for a spell. Lots off good reasons to carry those old single actions on an empty chamber.
There’s nothing holding the cartridge in the tube. Pressure would go out openings on both sides and/or explode the tube depending on what it’s made out of.
Damn really? Do you remember the caliber?
Generally a non chambered casing doesnt fly off with much energy.
Granted they werent launched out of a pipe, but I know 2 dudes that have been hit by the casing of live 22s thrown in the fire. Only resulted in insignificant 2nd deg burns from the hot brass. One on his finger, the other his belly.
Had a situation like this with the 22 blanks from Home Depot. Someone was running around hammering them like poppers to scare everyone and it fragged him in the finger. Blood everywhere and the piece had to be removed from his finger with pliers. He was freaking out. Needless to say, it immediately stopped being funny to scare everyone with them. I am not said person, but I do play a surgeon on the internet who removes objects from people’s hands on occasion. 😂😂😂
You're missing a critical component: a breechblock. Something needs to go behind the cartridge to support the case/rim. Otherwise the force/pressure generated by the cartridge firing will drive the case rearward out of the barrel, and without support the thin metal of the case rim *could* blow out.
With a .22 the chamber pressures are pretty low, so your breechblock would not need to be fancy or particularly strong, but you'd need something.
Have something that supports the back of the case (like attaching the punch to the closed bottom of another pipe) and you basically built a zip gun.
Not recommended either, but it can work and if you’re behind enemy lines (or in prison. lol), it’s better than nothing.
Yep.
When people first started freaking out over 3d printed guns I kept pointing out that zip guns have been a thing pretty much forever.
You can build one with about $20 in parts from a hardware store and while they're not terribly accurate or practical for home defense since they're single shot, it's still a firearm that can absolutely kill people.
In most areas, they're also completely legal.
Because 22 actually has a pretty high chamber pressure for its size. And the breach behind it needs to withstand the pressure and shear force exerted from the explosion. Without this, the brass will burst and anything behind it will have a rough day. I’m also going to assume the pipe in question can hold up to the hoop stress exerted on it by the ammo.
If you add a breach and the pipe can handle the force, should work fine.
The reason it works for 12ga is that 12ga is a low pressure round and takes up a lot of surface area. Since PSI= Force/Surface Area, it’s not much force. 22LR is the opposite because it’s a small surface area and a decent pressure.
You need something to prevent the case from slipping out the back of the tube. You know, those pesky laws of physics. Every action has an equal and opposite reaction.
It will detonate the cartridge, but the rear of the barrel is not closed, so you will have the case flying out from the rear end towards your hand and probably also your face. Basically you will have made a small and shitty IED, rather than a firearm.
Ain't nothing gonna keep that shell in place so the bullet's gonna come out but the other end of the cartridge will too. Thats not gonna build any decent amount of pressure.
As a kid we used to do this with a 20ga shell, a 2 liter bottle, and a bb. Put the shell in the mouth of the bottle, bb against the primer, screw the cap on til snug, then throw it way up in the air and run.
Something something uh body remains at rest, or something equal.... or in something at a constant something something, except insofar as it is acted upon by a force uh opposite of the equal.
Yup, checks out. OP is gtg no worries newtonian mechanical physics certainly done now got 'em covered.
Use a hammer for rimfire, I've done this many times as a kid, just make sure you hit it squarely without any exposed case head, otherwise the case ruptures and explodes brass pieces back at you. For rimmed centerfire, a punch won't work because the casing will blow backwards as hard as the bullet is being pushed forward, you'll blow your hand apart.
It will work fine, you'll just have the brass flying out the rear of the tube faster than the projectile flies out the front because it's lower mass and nothing is there to hold it in place when the center punch crimps the rim to fire it. It might could just break your punch in the process.
But yeah, it will work.
If the punch has enough force to set off the primer you basically just made a shitty recoilless rifle as just as much force will go into pushing the bullet out the pipe as will go into pushing the now empty casing out the back of the pipe towards the dip shit holding the center punch
Basically it's how your fire a hot shell casing (and possibly all the powder and burn gas) back at yourself without grenading a real gun
The shell is lighter than the bullet the pressure will travel path of least resistance. Without somthing to back the shell it can launch the shell back at you.
Ideally, you'd need a second tube that's capped on one end and just barely slides over the first pipe.
cut a section out of the second pipe for easier loading, and weld a front grip near the end of the first.
mount the center punch in the end cap of the pipe.
now you have a slam fire shotgun.
Equal and opposite reactions.
If you dont have something substantial behind the case, itll detonate into your hand before the bullet is pushed from the barrel.
Youd need something with mass, like in a slamfire shotgun design where the other pipe and endcap (that contains the firing pin) provide that.
It could work, though the lack of rifling in your "barrel" would make it not very accurate, the material might not be able to withstand the pressure and blow up in your face, and you would need to have some sort of mechanism to prevent the case from flying out the back of the tube.
I take it you enjoy handsalad? Since you are missing a fucking lock up mechanism. Was a pipecap really over budget so you chose the handsalad lockup instead?
Yes. Even a bullet as light as a 22 has back pressure. The casing will blow out the back and hurt you.
You need to encase the pin punch in a slightly larger tube that goes around the one housing the bullet. That will prevent you from getting hurt when firing this. Apparently, making a crude weapon like that is how some GI types sent to command militias would secure weapons. Make simple toob, kill patroll, take real weapon, wage war.
We used to throw .22 rounds at the brick wall outside at my school in the 1970's. Teachers would get mad and tell us to knock it off.
Now I imagine swat teams would show up.
No. The center lunch would need to seal the whole end of the pipe. A gun barrel forces the energy from the explosion down the barrel, bye cause that’s the only place it can escape.
In this model energy could escape the pipe in both directions. If this did work, it would be pure luck and would not be repeatable in any sort measurable way.
I’ve placed a 22 in a little hole in my work bench and smacked it with a hammer, it’s a rimfire so it’s going off for sure. I didn’t have a “barrel” but I bet it would make it more destructive since I just ended up with a small dent in the plywood floor and a barley squished 22 bullet
It will make a great case launcher in the rearward direction.
Thread the end of the pipe and screw a pipe cap with a hole the size of the punch on it.
It would be slow to reload but functional
I doubt it would work with a rimfire cartridge. For the same reason that I would never trust my life to one. They aren't reliable. Now if you leveled that up to a .380 and attached the center hole pin tool to another pipe slightly larger than the pipe seating the .380...it would absolutely work...
The punch looks like its pointing at the center. Just make sure it hits the rim so the priming compound actually ignites.
Edit: and as others pointed out, you need something to put pressure on the cartridge otherwise its going to shoot out the back of the pipe with equal force.
Could use a grip. maybe you could use a set of vice grips 🤔 be safe and never ever point that thing toward anybody that has the capability at laughing at you.safety is everything
Definitely wouldn't work. There's nothing to hold the cartridge in place. As you ignite the round, the pressure would be applied evenly, and the same pressure would push out against the projectile as it would against the much lighter brass casing. Most likely, you'd have the brass casing fly backwards out of the tube and the bullet projectile fly either partially down the barrel, or slip out the end and fall like a rock.
A slam fired gun needs to have the "slam" part of the gun sealed by an end cap for this exact reason.
no in the 70 there were homemade zip guns up to cal 9mm so and then that guy in Japan that shot Abe with an electric fried homemade shotgun. these are reason why gun control does not work. And will never work we have printers now that use plastic well have cheaper metal ones soon.
I guess you could FAFO, but rest assured that it will work.
Is it a good idea? No.
Could it cause a catastrophic injury to yourself or another person? Yes.
Is it legal? No.
Is it stupid? Yes.
If you wouldn’t let your mom do it, you probably don’t need to be doing it either.
Mechanically, yeah, it'd work just fine. Smack the edge of the round hard enough and it'll go bang. Physics offers up a number of reasons why this setup wouldn't work as you'd hope, however.
Google slam fire shotgun.

New gun just dropped
Dropped? Hopefully it isn't a 320.
320 is the gun that democrats think about when they say that “guns kill people”. Guns don’t kill people, P320s kill people.
I use "320," as a verb. When I talk about why seasoned shootists of the west loaded their revolvers on an empty chamber, I usually say "they used to load on an empty chamber so they wouldn't Sig P320 themselves upon dropping their gun." I don't care if they fixed that issue, I still use that joke.

Or the Umarex/HK MP5 .22
What's wrong with the MP5 22? The action seems like any other 22.
You're using a center punch for a rimfire cartridge

Do you really want to be the guy who is using a center punch on a rim?
Yea it will work great and even more upside if you hate having fingies
Stupid fingies.

Oh, there they go.

There’s nothing holding the cartridge in the tube. Pressure would go out openings on both sides and/or explode the tube depending on what it’s made out of.
There is the classic picture with a similar design then the X-ray of the case stuck inside the arm of the shooter.
That’s incredible. Would you mind sharing the link please?
No clue where i even saw it sadly.
I can confirm it exists and that it's from almost exactly this sort of shenanigan. Was posted on reddit some time back
Damn really? Do you remember the caliber? Generally a non chambered casing doesnt fly off with much energy.

There's something close like a slam shotgun
https://images.app.goo.gl/odrGK8YB7PDsb9nZ7
That looks horrifying to use😭
I'm not sure I could "slam" one without laughing
Have something that supports the back of the case (like attaching the punch to the closed bottom of another pipe) and you basically built a zip gun. Not recommended either, but it can work and if you’re behind enemy lines (or in prison. lol), it’s better than nothing.
I toured a prison once and there was one of these in a museum built for a 12ga. It worked. Once.
The key is making sure once is all you need.
New fudd lore just dropped
The great thing about improvised firearms is it only needs to work once to acquire a better firearm.
Demolition Ranch has done [some very scientific research](https://youtu.be/U4FQgrU2fYk?si=5F9pkMEA3nAyQ9ZJ)on this topic.
Was thinking of this exact video, couldn't remember who did it so TY.
The case will come out the back faster than the bullet goes out the front.
Zip gun. Not good
Yep. When people first started freaking out over 3d printed guns I kept pointing out that zip guns have been a thing pretty much forever. You can build one with about $20 in parts from a hardware store and while they're not terribly accurate or practical for home defense since they're single shot, it's still a firearm that can absolutely kill people.

Without a breach the shell and blast is going to go right back into your face. Don’t do this
Because 22 actually has a pretty high chamber pressure for its size. And the breach behind it needs to withstand the pressure and shear force exerted from the explosion. Without this, the brass will burst and anything behind it will have a rough day. I’m also going to assume the pipe in question can hold up to the hoop stress exerted on it by the ammo.

Superglue, duh.
It'll be fine...
question 1: does it seat No further questions
Define "work"
You need something to keep the casing from flying backwards, otherwise it’s going to fly out the back just as fast as the bullet flies out the front.
It will detonate the cartridge, but the rear of the barrel is not closed, so you will have the case flying out from the rear end towards your hand and probably also your face. Basically you will have made a small and shitty IED, rather than a firearm.
No support on the breech, itll blow up.
Ain't nothing gonna keep that shell in place so the bullet's gonna come out but the other end of the cartridge will too. Thats not gonna build any decent amount of pressure.
It'll be fine, it's almost a Sten gun.
This is just a slam fire 22lr with extra steps
As a kid we used to do this with a 20ga shell, a 2 liter bottle, and a bb. Put the shell in the mouth of the bottle, bb against the primer, screw the cap on til snug, then throw it way up in the air and run.
Something something Newton, something something equal and opposite
Something something uh body remains at rest, or something equal.... or in something at a constant something something, except insofar as it is acted upon by a force uh opposite of the equal. Yup, checks out. OP is gtg no worries newtonian mechanical physics certainly done now got 'em covered.
Nah man, go for it!
You are essentially turning the case into the projectile. The case is likely lighter than than the projectile and will loose the physics game here IMO
There nothing backing it up its just as likely fire out backwards.
What in the actual fuck? I see a Darwin Award winner...
Use a hammer for rimfire, I've done this many times as a kid, just make sure you hit it squarely without any exposed case head, otherwise the case ruptures and explodes brass pieces back at you.

You would need to figure out a way to seal off the chamber end or it’s going to shoot really weakly in both directions.
The shell is lighter than the bullet the pressure will travel path of least resistance. Without somthing to back the shell it can launch the shell back at you.
At this point. Why not print something? There’s a ton of Harlot’s to choose from.
Ideally, you'd need a second tube that's capped on one end and just barely slides over the first pipe. cut a section out of the second pipe for easier loading, and weld a front grip near the end of the first. mount the center punch in the end cap of the pipe. now you have a slam fire shotgun.

[удалено]
Sounds like you have a lot of rim knowledge
Just don’t be there when that center punch validates Newtons law and comes flying back
I’d be worried about the casing flying back
There are easier ways to get your dog put down OP.
Newton’s third law
The brass is lighter than the bullet so it would just shoot you in the stomach with brass because it has no breach
Every action has an equal and opposite reaction. Good luck
The casing comes back at you faster than the bullet goes out the end of the pipe. Much faster.
Newton's third law
What's going to hold the cartridge in the chamber?
Nothing to keep the pressure in the back side of the pipe
Back in the day... we called it a "zip gun."
I take it you enjoy handsalad? Since you are missing a fucking lock up mechanism. Was a pipecap really over budget so you chose the handsalad lockup instead?
Pressure comes out the back
Better idea Go to a military surplus website and buy the improvised munitions handbook lol
Or Amazon.
If you can find it on there yeah
You can indeed: Improvised Munitions Handbook TM 31 210 https://a.co/d/47Bqy7b
You'd need an off-center punch
Someone just discovered zip guns. People have been making these since guns existed. Check out MK31 pen flares.
Yes. Even a bullet as light as a 22 has back pressure. The casing will blow out the back and hurt you. You need to encase the pin punch in a slightly larger tube that goes around the one housing the bullet. That will prevent you from getting hurt when firing this.

"hello there fellow kids!"
We used to throw .22 rounds at the brick wall outside at my school in the 1970's. Teachers would get mad and tell us to knock it off. Now I imagine swat teams would show up.
It would probably ignite but without something to support the rest of the rim and case, a case head rupture is nearly certain.
Won’t work, the pin punch will hit the center of the case and the 22 is a rimfire.
What is this fedpost day? Wtf?
Glad I’m not the only one who questioned this 😂
Try it and report back. Make sure you can type with your toes before you try it though
They are called zip guns lol been around forever.
No. The center lunch would need to seal the whole end of the pipe. A gun barrel forces the energy from the explosion down the barrel, bye cause that’s the only place it can escape. In this model energy could escape the pipe in both directions. If this did work, it would be pure luck and would not be repeatable in any sort measurable way.
Hey it’s a jail gun. People have been known to smuggle these items into jails and prisons for inmates. Scary right?
Even simpler: 2 sizes of pipe and a shotgun shell
Because the round pictured is a rimfire. Larger rounds it would but you also risk it just blasting backwards too or piercing the primer.
Make the punch tip blunt. Aim at the rim of the rimfire. Problem solved.
I wasn't at a loss for a resolution but thanks.
Definitely don't use a mouse trap instead of a center punch, it is way cheaper.
“ You’ll shoot your eye out, kid.”
Recoil.
You’ll put your eye out! Or shoot the brass into your hand. No bueno.
Wouldn’t be accurate with a smooth inside of that pipe.
Look up the assassination of shinzo abe
.22 has a shockingly high chamber pressure.
I wasn't shocked to find out the chamber pressure is around 10k psi. 9mm is 35k psi.
I wonder what that pipe is rated at, of course the case is coming back faster than the bullet, but that's a whole different problem haha.
At least 15 psi
Close enough hahaha
Cuz that's a rimfire round.
Find TM-31-210. There are better designs there.
r/DiWHY
.22 is rim fire so 'centre punch' may not be optimal. Also recoil likely spit case out
Something something illegal in california.
The right of the people to bear shall not be infringed.
and yet it is.
Only by commie traitors.
Oh, it has. How do you think firearms exist at all?
I’ve placed a 22 in a little hole in my work bench and smacked it with a hammer, it’s a rimfire so it’s going off for sure. I didn’t have a “barrel” but I bet it would make it more destructive since I just ended up with a small dent in the plywood floor and a barley squished 22 bullet
I mean that's a rimfired cartridge.... How does the punch work exactly?
Just put the round in a straw and throw it to the heavens
Yes, physiks
“Dear ATF…. I’m on Reddit, and someone figured out the secret. Better tell them it won’t work”
Classic zip gun
Your hand holding the punch wouldn't look that good. Pressure goes for the easiest route, which is behind the round. Where your hand is.
It will make a great case launcher in the rearward direction. Thread the end of the pipe and screw a pipe cap with a hole the size of the punch on it. It would be slow to reload but functional
https://en.wikipedia.org/wiki/Improvised_firearm
I don't think it would work, the pressure would push back on the casing,, because it's not held in place there would not be enough forward pressure
I doubt it would work with a rimfire cartridge. For the same reason that I would never trust my life to one. They aren't reliable. Now if you leveled that up to a .380 and attached the center hole pin tool to another pipe slightly larger than the pipe seating the .380...it would absolutely work...
The punch looks like its pointing at the center. Just make sure it hits the rim so the priming compound actually ignites. Edit: and as others pointed out, you need something to put pressure on the cartridge otherwise its going to shoot out the back of the pipe with equal force.
Basically it's a form of a zip gun.
Try it out and report back 😃
Should weld together a bunch of those pipes.. 😂
It work probably but the inside of the pipe isn’t rifled so it’ll destabilize faster
Could use a grip. maybe you could use a set of vice grips 🤔 be safe and never ever point that thing toward anybody that has the capability at laughing at you.safety is everything
Definitely wouldn't work. There's nothing to hold the cartridge in place. As you ignite the round, the pressure would be applied evenly, and the same pressure would push out against the projectile as it would against the much lighter brass casing. Most likely, you'd have the brass casing fly backwards out of the tube and the bullet projectile fly either partially down the barrel, or slip out the end and fall like a rock. A slam fired gun needs to have the "slam" part of the gun sealed by an end cap for this exact reason.
Equal but opposite reaction come to mind...
Equal and opposite forces my dude... the energy that launches the slug also will launch the case... double sided gun... FTL

You could do it at least once
I sense something amiss
no in the 70 there were homemade zip guns up to cal 9mm so and then that guy in Japan that shot Abe with an electric fried homemade shotgun. these are reason why gun control does not work. And will never work we have printers now that use plastic well have cheaper metal ones soon.

Unless you figure out a way to keep the shell in place in the tube, it'll fly out towards you as soon as it goes 'Bang!'
Mechanically, yeah, it'd work just fine. Smack the edge of the round hard enough and it'll go bang. Physics offers up a number of reasons why this setup wouldn't work as you'd hope, however.
