Is this as ridiculous as it sounds?

[BobOfTheFuture]

Ok, so the video game "Call of Duty- Modern Warfare 2" Is soon coming out.

In it, I have heard, they give you the option to suppress shotguns.

I always thought this was not possible, but want to make sure I am right before I make a donkey of myself.

Anyone have any info on this?

Obviously this is just a game, but these games tend to strive for realisim, And, honestly, these types of games introduce more new people to shooting then the NRA can dream of, and in states they consider "lost" like my home state here. (NY)

That is far less dangerous then the reverse. When people tend to treat real life like a video game.

That's an interesting statement. Games no more introduce people to shooting than dime novels, movies or television have. They may pique an interest, but it certainly isn't an "introduction" to shooting.

As to suppressed shotguns, yes, there have been attempts, but, no, they've not been practical or very successful. What you're seeing is another example of misrepresentation of firearms, firearms technology and/or firearms use.

 

[BobOfTheFuture]

Or a television show, or a movie, or a radio program, or what they heard on the telegraph machine or what they read about in a newspaper...


I could keep going till when ogg told grok about how he killed a squirrel during the caveman days.

Don't make this an argument about how wrong games tend to be, please. They are no different then any form of entertainment or media.

There have been several interesting threads on this in the Shotgun forum:

Semantics, Mod.

In that vein, then the NRA doesn't introduce anyone to firearms, unless they hold range sessions....

Ah, thanks rbernie! just what I was looking for.

Honestly, didn't search for it because I thought it was too unrealistic of a thought to have been posed as a question.

 

[scndactive]

I seem to remember reading some thing about a guy that made ridiculously long barrels for shotguns (40+ inches) in order to suppress the report down to that of a .22 short. Supposedly so they could hunt behind rural neighborhoods without disturbing the locals. The trade off was having to hunt birds with a 5 ft shotgun.

 

[BobOfTheFuture]

Heh heh heh.


Heck, with a bullpup design it will only be as long as an old muzzleloader

Actually, I think the vidja games do aid in interesting people in firearms. I have taken a few people shooting because they mention some pistol/rifle in a video game, and I happen to have that pistol/rifle or a close variant. Once I mention that "hey would you like to shoot a real one of those?", they are generally pretty interested.

Yes, there are suppressors for shotguns. they are more common in Europe, but very rare in the U.S. I only know of one company in the U.S. producing suppressors for shotguns, and they will only sell to gov't agencies as a matter of policy, not law, there was an article in SWAT magazine in 2000 about it. The August, 2008 issue of Small Arms Review has an article on suppressed shotguns, and the author also describes making his own shotgun supressor in it. See links for more info.

I dont know if it is possible or not . The way a supressor works is by slowing down the expansion of the gasses escaping from the end of your barrel and cooling them at the same time . The inside of a supressor is a series of spacers and baffles stacked on top of each other . The baffles have holes the same size as the bullet and they are line honed to keep them straight with the path of the bullet . Subsonic ammo has to be used to keep the bullet from breaking the sound barrier ie super sonic . A gun that has a closed chamber (automatic or bolt , break style) must be used to keep the gasses from escaping anywhere but through the silencer . So the old movies you see where a supressor on the end of a revolver and it is silencing the discharge is purely fiction . A shotgun supressor could be done for slugs only I would imagine . I just cant see how a charge of shot could travel through all of the baffles and come out with any kind of accuracy at all . Even a conventional style of supressor on a rifle or pistol will kill accuracy . Another thing that movies and game dont portray accurately is the sound of the discharge of a supressed gun . They "usually" sound about as loud or maybe a little louder than the sound created when you clap your hands together really hard and I mean really hard . Inside a room this would sound pretty loud .

ive read about this a few times and from what i gather it works best when the shot sin in a capsul not a standard wad

Bruno2, one could actually silence a 1895 Russian Nagant revolver.

Also the OTs-38 silent revolver is silenced revolver, although the silencer is part of the weapon's design and not on the end of the barrel.

P.S. I would love to get my hands on a OTs-38.

The baffles have holes the same size as the bullet and they are line honed to keep them straight with the path of the bullet . Subsonic ammo has to be used to keep the bullet from breaking the sound barrier ie super sonic .

Not true, bore is oversize in a supressor and is usually not honed. Subsonic ammo may be used, but is not necessary. Many suppressors reduce noise to a safe level without using subsonic ammo.

A shotgun supressor could be done for slugs only I would imagine . I just cant see how a charge of shot could travel through all of the baffles and come out with any kind of accuracy at all .

It can be done and is done. See links in #14

Even a conventional style of supressor on a rifle or pistol will kill accuracy .

Completely and Totally FALSE. This seems to be a popular idea among people who have never used suppressors.:banghead:

They "usually" sound about as loud or maybe a little louder than the sound created when you clap your hands together really hard and I mean really hard . Inside a room this would sound pretty loud .

Depends entirely on the gun and suppressor. Some are almost "hollywood quiet" and some you still would want hearing protection.

Sorry for the thread hijack, I just get frustrated my suppressor myths.

Man, it is a really good thing that I did not learn about silencers from certain members on this forum. I might have believed that it is not possible to effectively suppress a revolver (like my 1895 nagant), a high powered rifle (5.56, 308, 338 rum), any semi-auto action or a shotgun. Too many people are willing to believe in or spread fairy tales to try and get their fellow gun owners to limit their options.

Spacers are not required if the right kind of baffle is used. Making the baffles bore the same size of the bullet is a recipe for destruction. Wipes are the only kinds of internals that can touch the bullet without wrecking the silencer, and then they wear out quickly.

The action noise of most firearms is much less than the muzzle blast noise. This is why a suppressed AR-15 can be hearing safe even with the action near the shooter’s ear. When shooting out in the open, the shock wave from the supersonic bullet does not pass the shooter’s ear, so it is of little consequence. While anyone down range will hear it (and it may be loud), the source of the noise can be difficult to locate if the bullet passes any objects along the way to the target. In other words, I do not give a damn about sonic noises. Muzzle noise and action noise are my two greatest concerns.

It is sad to hear of so little imagination when it comes to shotgun silencers. There are at least two solutions to the opening wad “problem”. One is to use a perforated tube inside of the can. This acts just like a ported barrel and traps the gases in the silencer and allows them to expand very well. In the end this design does not work as well as a rifle silencer with baffles from what I have read. I heard the Reflex shotgun cans only reduce noise by 17 decibels which is not so well compared to the 30 decibel performance of other designs. The other way to avoid catching an opening wad inside of the silencer is to make the baffle bore wide enough so that the wad can open as it passes through. This of course lets out more noise and reduces the effectiveness of the silencer.

If I thought that silencers would ruin the accuracy of my firearms, then I would have never bothered to make any. Spending $50 on material plus the $200 tax certainly would be a big waste of money if it made my guns less accurate. My homemade silencers are precisely aligned to the bore to prevent baffle strikes. The only times I have had baffle strikes was when a can came unscrewed and drooped on my 9mm pistol, and the time I tried a new cast load on my 50 caliber rifle that yawed too much and hit the last baffle and end cap. Other than those problems, the only difference is the change in point of impact due to the weight of the silencer on the barrel. This is easily compensated for by adjusting the sights or scope.

Shooting suppressed weapons at long range without hearing protection is kick ass. Too bad people here are trying to talk themselves out of a nice experience.

From post #15 http://www.saddleryandgunroom.co.uk/..._Hushpower.htm




Note that the design does not use separated baffles that the shot wad has to "jump" over, but a continuous fenestrated tube. Using that design it would appear entirely possible to "silence" any shotgun with any type shot/projectile.

Rand, I agree. Here is a silencer for a 50 BMG

Here is some of my work. All of the silencers are homemade on ATF form 1's.

I've seen Hushpower shotgun moderators used. Very quiet. Some attach to the end of the barrel so increase length and ruin balance, but others are integral and so don't increase overall length. However, they're bloody heavy! The moderator itself weighs the same as an AR15!

 

[Bruno2]

A really good friend of mine just purchased one for his p22 and I cannot think of the brand , but , it has a picture of the statue of liberty on the box . The shots are just about everywhere when the can is on . The shots vary so much that adjusting the POA is useless . By using subsonic ammo is the only way I have ever seen one perform anywhere close to Hollywood standards of supressed discharge . Ranb I am sorry that I was not considering your personal preferance of supersonic noise downrange b/c once again the comparison was about hollywood and being realistic . I would like to apologize to RANB for not having the knowledge about the nagant revolver and the capability of being supressed . I hate to keep repeating myself , but , it was comparison of hollywood and reality again .

 

[WinchesterAA]

Ranb, the questions I'm about to ask could no doubt be answered by many people, however you've just proven that you're quite knowledgeable of the subject, therefore I feel fairly confident that any answers you provide would be of great value to me.

I would appreciate if you could elaborate on certain aspects of your designs -

Why conical baffles? It's an obvious question, with an obvious answer, but the details in which I am interested in. What are the factors influencing your decision to use a conical baffle, and what is the proportion regarding spacer length, and the size of the baffle?

What is the ID of the smallest end of the conical baffle, and why did you choose to make it that size? (A somewhat educated guess from myself is that it's approximately .02" wider than the bullet going through it.)

What type of metal do you prefer for your silencers?

A question regarding the basic fundamentals of threading-

What do the numbers in 1/2-28, and 13/16-20 pertain to?
I'm inclined to believe that 1/2 is indicative of a rate of twist, but what specifically does that mean, and what mathematical formulas, if any, would be used to elaborate on this subject?

The 28 may pertain to the amount of threads per inch, but I am unsure of this.

Also, some personal history would be much appreciated, as I hope to one day have my own machine shop in my garage or basement if I ever have one, just because that's what makes me happy. I love making things, and I love even more the idea that I can make things really well.

What tools do you use, and how did you go about acquiring them?

Additionally, my questions can most definitely be viewed more as a general machining question, as opposed to anything specific, such as the manufacture of silencers. Though I do love shooting when it's not so loud, I don't really care about the noise that much since earmuffs are something I carry around all the time, because most of what I do is loud - not just shooting)

Thank you for your time, sir, and I hope you'll fill in the details I'm obviously not quite grasping at this moment.


Bonus question - What are the names for the branches of math that you utilize most often? (trigonometry, algebra, etc)
