    Are they as silent as in the movies or is that just for show? I have never fired one and was curious. In addition what is the general life span of a quality silencer? Im trying to figure out if its worth purchasing so I stop pissing off the neighbors.

    is a silencer caliber specific? can i shoot a .223 thru a 9mm can and get the same sound reduction as a dedicated .223 can?
    thanks

    Yes, no, kinda, sorta.

    In theory a dedicated can to one caliber should be the most efficient. That is assuming ALL variables are the same.

    First thing you need to know is what pressures a can is rated for. While a .223 bullet will easily pass though a 9 mm can I am only aware of one that can handle the pressure.

    Now many people have .30 caliber cans that you can easily use on any caliber with less pressure then what the .30 cal can is rated for. Some are rated for .300 WM and some just for .308.

    Now is a dedicated .223 can quieter then a .308 can on a .223? In theory the .308 can should not be as quiet because of the larger exit hole and the smaller bullet. Problem is that most .308 cans are larger then .223 cans so the extra space will be able to suppress better negating the hole size.

    Then when it comes to how loud cans are there is the db test meters and ears. For the most part people dont say "wow that one can was quieter/louder then the other". You will usually here them talk about tone. One with more db reduction could have a tone that is not as pleasant as one with less db reduction.

    To cover your bases best and get the most sssshhhh (bang does not fit here) for you buck a person should own 3 cans.

    .22 that can be taken apart. .22 is very dirt and will plug up a regular can fast. Most larger can are not able to be taken apart for cleaning. Also most .22 cans are very small and light.

    A .30 cal can. You can shot anything .30 or under with it.

    You could easily get away with just the top 2 but a 9mm can is nice. It is very quiet on a pistol or carbine. Still cheep to shoot and just plain fun.

    Does that help at all?


    EDIT:

    I trust you know that you can't "silence" any round that exceeds the sound barrier. (1100 FPS at sea level) Ergo, a 223 will not be silenced by a 9mm can...suppressed a little but only a LITTLE.


    That is mostly true. There are 2 noises a gun makes, the muzzle blast and the sound of the bullet breaking the speed of sound if the round is supersonic. Silencers reduce the sound of the muzzle blast.

    Depending on a few factors shooting supersonic ammo with a silencer can still make quiet a difference. This is not to say it will be quiet like shooting SS ammo. Just saying that on many guns using a silencer even with supersonic ammo will be greatly reduce the sound to the point that it is pleasant to shoot without hearing protection. This may still not be totally hearing safe from a true db standpoint.

    Simple answer you can shoot any smaller caliber thru the larger can, but your noise reduction will suffer!
    I have a TAC 65 can for 22 pistols and a AWC 223 can for M16 rifles. Both are threaded 1/2" x 28. The TAC 65 has aluminum baffles and the AWC has stainless. The TAC 65 will not handle the 223 pressures.
    There is a noticable noise increase when using the AWC can on a 22 pistol compared to the TAC 65 can.

    Nwcid,

    It is my understanding that in order to hear a supersonic projectile, it has to pass by you. In otherwords, the sound waves have to be able to strike your ear drum, and standing behind the weapon you do not hear the crack from the sound barrier.

    What is your take on this? I have shot suppressed weapons with supersonic ammunition, but I couldn't hear the crack...my hearing is about shot anyway.

    I can hear the supersonic crack all the time.

    I use 22 cans on 22LR firearms
    I use 223 cans on my 223s
    I use 30 cans on 6mm, 7mm and 30 cals.
    I use 338 can on my 338 Lapua
    I use 40 cans on 9mm and 10mm
    I use 45 cans on 45s

    I am still waiting on the 50 can for my Windrunner.

    You can hear the sonic crack from behind the gun if there is something for the sound to rebound from when shooting a regular unsurpressed gun. When I shoot long rang here in hilly woods the sound of the bullet makes more noise then the shot itself from my POV. I hear the crack half a second after the shot itself has faded.

    though if there is nothing for the sound to bounce back from, you dont hear the sound of the crack, just the shot itself.

    yes, and thanks to all who replied. that's why i love this place![:)]
    i picked up a 9mm can for my colt sporter and figured anything smaller caliber would work. i didn't think about the pressure differences. saved me from ruining a perfectly good can!
    with that in mind if i get a 45 can, can i shoot 44mag thru it?
    and, one more, what would be the outcome if i put a can on my 8" PORTED anaconda?
    thanks again

    btw, this is my first silencer, hence all the dumb questions![:I]

    On the .44 in a .45 you have 2 options. Ask if the .45 can is rated for full power .44. If not download your .44 to a lower pressure, you are probably going to want to load it subsonic any how. I have heard very impressive things about suppressed SS .44 carbines. For example I do shoot a .30 caliber rifle round thought my 9mm can all the time, it is my .300 Whisper. I am loading subsonic ONLY for use in this set up.

    Silencers and revolvers dont get along well since you have the cylinder gap for lots of noise to come out of. This will be worse with the increased pressure from the silencer. There is one Russian revolver that the cylinder actually moves up tight to the barrel so this would be the exception.

    Same for shooting anything ported. Your noise is going to come out of the ports. The exception is some silencer designs that use ported barrels internally.

    Now I cant speak to the science that you listed above. What I can say is you will hear it.

    Silenced sounds are hard to describe and they can vary depending on what kind of area you are shooting in.

    Most of the places I shoot are fairly open areas. Shooting supersonic suppressed can roughly be compared to someone shooting a .22 50-100 yards away. While you do hear it the sound is very displaced. On all my guns the you are still able to hear the noise of the round hitting the target (if it is a hard target).

    TSR1965,

    You can hear the crack and travel of the bullet going downrange Using a silencer on a .223/5.56mm. It is not as loud standing behind the bullet as it is going past you. I've heard this many times. Ak's have a pretty healthy 'snap' as well. FWIW, if you listen you can hear a .22LR bullet going downrange as well. It really makes noise when shot crosswise to the wind.

    I'll qualify the use of the silencer with the fact it was back in the mid 80's with I believe late 60's or early 70's technology. We've found better ways to suppress sound since then.
