I've always wondered, is the mussel velocity less for a auto than a revolver.
Don't know how it's "interactive" but it's a nice informatic
+straw walker It's hard to compare the two, I don't recall offhand of any semi-auto that shoots a magnum round. So to compare the velocity of a magnum to an ACP is kind of a poor place to start. Given how the guns function though, all the gas in the revolver is propelling the projectile where in the semi-auto some of the gas is moving the action while the rest is propelling the projectile. So if they both had the same round the revolver would probably have a higher velocity. 
I think the desert eagle fires a 44 mag
+Mike Heminger It does. The review I found said it was less powerful than a revolver firing the same round.

Nice Infographic
The Desert Eagle has two models that fire magnums, 44 mag and 357 mag. Muzzle velocity means little by itself. The strongest loading of a 44 mag is about 1600 feet per second using a bullet that weighs 240 grains. A round of 22 long Rifle that has the same velocity might use a bullet that weighs 30 grains. The difference between the two is the amount of foot/lbs. of power. The 22 LR might have 80 foot/lbs. Where the 44 mag might have almost 500 foot/lbs. of power.

Such an infantile obsession 
+Ben Beath people built and manufactured this stuff without computers. gun manufacturers industrialized the world when they made inter changeable parts! did you know THAT?
GUN MANUFACTERERS developed the ASSEMBLY LINE, no joke. we owe a lot to SHOOTERS!
Tim Mc
Awesome graphic, but I think the very first item is incorrect. What's called out as the "cartridge" is the "casing". The "cartridge" is the entire assembly.
+Steven Walker Actually, in most revolvers there's a pretty good gap between the cylinder and the frame. In some cases, you get some pretty good flash between them. Dunno if it's more or less than the amount lost in cycling the action of an automatic, though. Personally, I'd expect barrel length to be a bigger consideration in muzzle velocity - longer usually equals faster (and more accurate).
+Patrick Ryan The length of the barrel on a pistol is much less important than it is on a rifle, with longer barrels only having a small advantage. The main reason for installing a longer barrel on pistols is to increase the sight radius. Even the difference between muzzle velocity between revolvers and semis is negligible. I would be more concerned with the caliber I'm using (I use a 44).
+Babu AndCoffee I'm aware that barrel length doesn't play a large role in muzzle velocity - I simply said I suspect it's a larger role than revolver versus auto (but don't know for sure). And I dunno about you, but a longer sight radius makes me more accurate! I have four autos, two carbines, and a revolver, so I can sling various calibres of pistol round downrange any number of ways... :)
+Sean C Breasts are an infantile obsession, for good reason they give life, and are warm and soft.
+Patrick Ryan I wouldn't be too concerned with it, because if I'm using a revolver, you can bet I'm not using some lousy mouse round. As for sight radius, I've never noticed any difference between my ported 4" 44vh barrel and my 6" slab barrel outside of recoil (damn 1 1/2lb of metal does the trick rather well). I don't tend to shoot past 25 yards with pistols, and anything beyond that I pull out a scoped rifle for. I like shooting 400 yards with my .308 700. Real fun.
+Babu AndCoffee The only time I shoot light rounds in general is when I cheap out and shoot .38 in my .357. :)
+Matthew Barby while this is very cool animated infographic and borderline "Gun Pr0n", it's not "Interactive. ;)
+Christian Quiles

You did a super job at wrapping things up, and I'm not just saying that because I have to! 
Also the definition of the caliber is incomplete. While the pre-fired diameter of the bullet could be called the caliber, it is more informative to use the distance between opposite lands in the barrel as the definition of caliber.

I've been seeing more and more interactive infographics from this company Animagraffs. His work is really great! The last one I saw was how the engine works. Really great stuff Animagraffs!
if the round is PLACED correctly the one CATCHIN' ain't really going to debate anything! " SHOT PLACEMENT" is EVERYTHING.......
+Patrick Ryan My grandpa raised me on high caliber revolvers and bolt guns. If it doesn't start with a 3 or a 4 and rocks your world when fired, it's not worth a damn. 
Having the bullets come off the magazine faster than they go out the barrel is called a jam.
+david hartzog, if you can't understand the reason a free people needs the right to keep and bear arms, then you should educate yourself.
+John Miller He's not saying there aren't brains here...there are just more guns than brains. Regardless of the debate just wanted to clarify that. ;)
+Warren Tarbat Huh? Almost all product is the past 200 years? That is the most craziest comment I have heard all day. Since this is a Gun post. First automatic gun was created by a Mexican general  manufactured in Switzerland. Who was the first to invent gun powder? hint hint not a American..
+straw walker Depends on barrel length, and the ammunition p +p. 110 grain vs 120 grain. Caliber and hollow point or ball. Actually the barrels are about the same in length, unless you go snub nose, the bullet will exit quicker but slow down quicker because it is exposed to friction 1 billionth of second sooner.
On some pistols, the barrel and therefore the chamber do slide back a bit on recoil. This is used, for example, to disengage the barrel from the slide on the 1911.
+Lee Gillaspie Yes I understand that but we have learned from the Chinese how to make gunpowder. First known American case was in the 1800s. Which is pretty close to 200 years.   
+Lee Gillaspie Part of the reason America invents so many things is because we're a melting pot. Brilliant minds from all around the world. To say America invented pretty much everything is the past 200 years is a complete false statement.

I like it. I love my guns!!!!!!  WE must stick together as gun owners.
Owning weapons only gives an illusion of safety and freedom. If it were otherwise, the Germans would have overthrown Hitler. He instituted American-style gun laws, much more lax than before of after him. Further notes of interest; while a defector in Russia, Lee Harvey Oswald maintained the marksmanship he learned in the Marines by joining the local shooters' club. When the Berlin Wall went up, the East German "Peoples' Militia" again didn't take the opportunity to revolt, despite being issued assault rifles and live ammunition. Finally, the amount of weapons crimes being committed locally seems less dependent on how many firearms people own than in whether or not it's associated with "manhood," the way it is in the Deep South, the Latin Countries and many Muslim countries. Canada and the US have similar weapons ownership levels, but Canada has far less gun crime.

As far as I can tell, dictatorships fear their people finding out the truth much more than owning guns. Cuba has "peoples' militias" but has never used them in a war with the US or had one revolt. However in the 80's Congress funded a high power radio station to broadcast to Cuba. The Castro government promptly retaliated with its own high power transmitter, which blanked out radios all over the US. Reagan stopped the transmissions from the American station (such a 'brave' cold warrior he was). To this day, the Cubans jam American broadcasts aimed at Cuba, and at lower powers, jam Miami commercial broadcasts so that Cubans can't receive them. Similarly, in Nazi Germany listening to foreign broadcasts could get you serious jail time, as it could in Russia and China during the Cold War. The Russians still pull stuff to prevent their people from getting good news (as we know from the coverage of the Crimean crisis) and the Chinese have all kinds of active censorship. It's worse in North Korea, Iran and Saudi Arabia.

In the US, propaganda outlets like Fox News rely on confirmation bias. In other words, if you listen to Fox news, you'll get so used to thinking it's news that you won't trust the truth when you hear it. I'm sure we've all met people in that category. I recommend explaining confirmation bias to them. Soviet propagandists were big believers in it. I sometimes wonder if Fox didn't hire some after the Cold War.

And oh yes, popular slogans about "guns protecting freedom" are wonderful examples of confirmation bias.

+George Wolf I was taught to shoot by my dad and uncles....  I was only a little kid and I was hunting and tracking. I was taught not to waste ammo.  If it is injured u kill it with your hands.  They were poor and hunted for food. My uncle was in WW2 and my other uncle in Korea and Nam.  I was taught well.
if you want to know how powerful a lie is then talk about Hitler.
+Jeff Williams: That's why I said "some pistols". I'm not aware of any 1911 derivative with a rotating barrel or locking bolt, but I could be wrong.
It reminds me of Turtles laying eggs in a hole
dug in the sand during the season.
Journalists and people who write for movies and TV shows should be forced to look this over.
old news to me, but great refresher!! glock 21 will stacks bodies high
I thought this was all common knowledge. 
Guns is guns.

(This is really an info graphic on how bullets work though)
I'd like to see a nice transparent animation of a bullpup style auto firing. In real time and slow motion.

Anyone operating a firearm, should know this. :-)
From the graphics of this I'm going to guess theres some subliminal sex shit in it to help secure the socialist job security, and pass on learning it from the world wide eye.
+Steven Walker True, but .357 Sig is comparable in stopping power to the .45. That has been proven, dependent on brand, load, HP +P, and all that good stuff. Then again, proper target placement, you can take anyone down with bullets for .22 to .51 
Does a longer barrel cause the gasses to propel the bullet faster /further or does a heap of other factors affect this
Bill K
2 Damono Conti ~ a longer barrel [IE] more rifling can cause the projectile to have more spin. It is a balancing act between amount of Powder, [IE] casing size, projectile [IE] bullet size shape. Rifling the twist. Barrel length. As well as primer to ignite the powder.
Take Care, Bill Kearney. :-)
(One of) the best infographics I've seen - very clear for the user indeed.
its been quite a time i m mad on gun i jst love gun not to kill anyone but to learn
AND it explains the difference between a Magazine and a Clip for those who are still uninitiated to firearms and the appropriate terminology.

+ George Wolf. As to guns creating an illusion of freedom. Elementary History, The American Revolution. The minute men!

Guns are typically owned for several reasons : Primarily for Sport, Target Shooting, Competition Shooting, Hunting. Also to put food on the table & thin the herd of certain animals.
Also to defend your family homestead etc.. from intruders wishing to do harm.
collecting purposes, like a piece of history or as a investment. Last I would say as a way to insure freedom.

Look at any state that has a liberal Cary Permit. Crime is far lower.
Take Care, Bill Kearney :-)
I guess it's true....guns do pull their own triggers...silly me

4 a U.S.Marine..that the Monistat looking anime of a mag & a lipstick dildo gets more likes & shares than any military pic showing our sacrifice for this great country is just sad & shameful
Aapke phone par MOBILE INTERNET uplabdh hain!Aapko INTERNET SETTINGS ke 2 SMS ayenge.Ab OPTIONS se SAVE select kare aur MOBILE INTERNET use kare!.Pin is 1111
Guns are cool. Too bad it's so hard to get one in Poland... Od maybe it's better...? ;-)
Its really amazing hw it wrks...
Don't forget the targets they are going to. Mainly humans
Very informative. Every family should have this knowledge for safety n survival it's also our 2nd Amendment Rights to carry.
well,all I know is it that it works
Tom most of the targets are probably made of paper or cardboard ,not humans.
Ahhh man. Now all the gum grabbing politicians who write gun laws have a diagram to show them how things work now.


I'm not big on guns but I love the animated infographic.
+Douglas Bujum that makes no sense. I know that you liberal's think that guns just jump up on their own and shoot themselves. 
Mechanically speaking, most guns are incredible feats of engineering and design.

Man just needed a more efficient and accurate rock throwing device and came up with the evolution of devices to get the modern guns of today. Note: Not all guns are firearms like the one demonstrated here. 
+Mahdi Ahnaf Hasan the gun, in this example, has a firing pin (a straight metal rod similar to a thin nail which functions as an energy transfer device) that when struck on the back end with strong force by either the "hammer" (a spring activated metal actuator that hits the firing pin when released by a pull of the trigger) or a "striker" (a type of internal hammer) is pushed by a strong spring in the longitudinal direction (length wise) the opposite end of the firing pin moves through a small hole in the "bolt" (which is the component that locks the cartridge into place within the firing chamber from the back flat face of the cartridge) area and strikes the primer at the back of the cartridge casing.

When the cartridge primer is struck hard enough by the firing pin, a small chemically reactive explosive charge is set off inside the cartridge casing which in turn sets off the propellant (main explosive powder charge) inside the casing.

The expansion of the resulting explosion of the propellant instantly creates enormous gas pressure inside of cartridge casing, which forces the projectile (bullet) rapidly away from the casing and (hopefully) into the "breach" (the back end opening of the barrel where the projectile and the propellant for the projectile are made ready to fire through the barrel) of the gun barrel.

The explosive gas always takes the path of least expansion resistance as in continues to push the projectile further down the barrel until the projectile has exited the muzzle (the opening at the front end of the barrel) of the gun barrel. The remainder of the exploded gas now has an unrestricted way to expand and eventually dissipate through the now unobstructed barrel and muzzle, into the open air.

The projectile is sent on its way to the target by leveraging the kinetic energy of the explosion plus the mass of the projectile and was guided by the barrel to improve the accuracy of the
trajectory. It is all physics and chemistry.

I hope that this helps your understanding of how the firing "action" of a typical firearm works.

The cycling "action" (making the gun ready to fire again) is well illustrated in the diagram. it 
are you aware of an un-automatic weapon system? Maybe their 105s that would leave a mark.
+Lee Gillaspie I an quite aware that the chamber doesn't "move" as a part of the action of the handgun. However, the chamber is expanded and opened then subsequently closed (by the movement of the slide) as a part of the cycle of the action, when there is another round being chambered from the magazine. The diagram is accurate for the cyclic action of today's simi-auto handguns.

What is not shown here is the case extractor that is attached to the slide that pulls the expended cartridge out of the chamber, and the case ejector that ejects the spent casing from the gun through the election port of now open chamber.

As is the case will all of the simi-auto, including 1911s (a beautifully mechanical gun) that I train with and shoot. 
+Lee Gillaspie, rack the slide on that 1911 slowly and watch. For the first 1/4 inch or so, the barrel (and, therefore, chamber) moves back with the slide, while the swinging link pulls the back of the barrel down to disengage the locking lugs. When they're fully disengaged, the slide continues backward, and the barrel stays put.

I just did this on my Para-Ordnance P15-40.

Granted, John Moses Browning's original 1911 design may not do this. I've never had one apart, or looked specifically at this. I'd be a bit surprised if it didn't, though.
I almost got a new 1911 recently, but I didn't have a tazer on me, when the dude I know from experience was packing ask me questions about some sneaky, now I gotz a new gun around hear somewheres do you read-over.
+Lee Gillaspie, I just examined an honest-to-Browning 1911. It has the same swinging link (the little gizmo that the slide lock/takedown lever slips through), and the same locking lugs at the top of the rear of the barrel, and the same action as the P15-40. The barrel moves backward with the slide for the first quarter-inch or so, then disengages and stops as the slide continues its rearward travel.

The graphic is exactly right.
+gerald miller  Tell that to Tamerlan and Ibragim and those in the grave that took one for Justice. Just saying.
