 Barrel longer make a .22 rifle more quiet?

From what I understand, the longer the barrel, the more quiet it is and vice-versa, so wouldn't a longer barrel or a barrel extension for a .22 possibly make it as quiet as having a suppressor, except this time it's perfectly legal?

Well, not really. The cz lux is proly the longest bbl made on a stock 22, and it is 28 inches long , I believe. Even this does not cut the crack of a bullet, if it is still leaving the muzzle supersonic. Which is the whole key.

along the same lines (hope this is not a hijack)
why do the CB's crack out of a pistol but a rifle (18in barrel) no crack?

But then a silencer won't cut the sonic crack either.

it may just seem like a longer barrel is quieter from a shooter perspective because the shot noise is further from you with the longer barrel.

sorry but not true, the cb makes no noise in the rifle but a big crack out of the pistol, now other rounds I don't know about that
why is that? experts?

Hmmmm...maybe the longer barrel actually slows the bullet? I seem to remember an old article in a gun rag about AMT. I remember they said that they found (IIRC) that the optimal barrel length for velocity/accuracy was something like 12", so they made their barrels with an actual bore of 12" but with a "bloop tube" to make them a legal 16".

The decrease in the noise is not due to a slowing bullet, but rather the pressure being less when it is released.

Blow up a ballon and when it pops you get a loud bang. Put the same amount of air in a bigger ballon and the noise is less due to less pressure.

First of all, it is perfectly legal to have a suppressor.


It has been my experience that the longer the barrel, on a .22 rifle, the quieter it is. I own two .22 rifles with extremly long barrels and IMO they come very close to sounding the same as a similar rifle, suppressed, The two rifles were both purchased from the CMP and were military training rifles, so they are pretty big in size. I believe they both have 26" barrels. One is a Remington 541X and the other is a Mossberg M44. Both of mine have been threaded. IMO, the suppressor doesn't really do a whole lot. They are both very quiet anyway. One of my buddies also has a Mossberg M44 and I frequently shoot with him off a bench where he is shooting right next to me. His rifle is so quiet that I have felt stupid for buying a suppressor. Point is that it isn't just from the shooter's perspective.
This whole thing with the supersonic crack of a bullet is WAY over blown on the internet. Yeah, it is there. But, that doesn't mean it is a waste of time to shoot supersonic ammo through a suppressor or to shoot supersonic ammo out of a long barrel .22 rifle. Both will be quieter than a non-suppressed gun or a shorter barreled gun. In addition, there is no reason at all why you can't shoot subsonic ammo, CB caps, or what have you out of the long barreled gun or the suppressed gun. Or, you can be like me and do all of the above: shoot a suppressed, long barreled .22, with subsonic ammo.

Here is the Mossberg M44 with a Tactical Innovations TAC65 can.

IIRC .22LR optimal barrel length is around 16".. After that the bullets start to actually lose velocity.. Shooting subsonic ammo through my Remington 513T with the 26" barrel is VERY quiet.. my air powered BB gun is louder.

It's what I use in my back yard for target shooting.. As suppressors are a no-no in my state.

No, because a silencer gives gas a place to go, and move about, and stall, and switch directions, and turn left , and turn right , etc., etc., so you don't get all the gas, still expanding, popping out right at the end of a muzzle. this is also the same reason you get a crack, out of a 2 inch snubby bbl, with cb bullets; that expanding gas is still balling up , in one direction, and is trying to leave the muzzle supersonic. So a longer bbl, helps to slow down the expansion of the gases, and also slow down the speed of the bullet, and if all this happens internally, then you get less of everything as it leaves the muzzle; as far as a surpressor goes, it works a bit diff, by giving the gasses a diff place to expand, and go , and turn, and cool, etc., but it is still the same principle mentioned above; let everything get less of everything, as it leaves the surpressor.

I would just go with subsonic rounds. If you haven't tried them, its pretty fun being able to actually see your rounds in flight.

How long of an extended barrel can you get for a 10/22?

I saw a 28" barrel for the 10/22 over on RFC, but I can't remember who made it.

semi auto will let noise out the action as the bolt cycles

Yeah, shooting those aguila super colibri (powderless 500fps 20gr rounds) out of my 5.5" ruger MKIII is alot louder than the same round out of my 18" Mossberg 702. With the rifle they're so quiet all you hear is the hammer drop and the bullet hit. With the pistol you definetly still hear a loud pop. Although... you aren't technically supposed to fire that ammo out of a rifle length barrel (or so it says on the box). The bullet supposedly could drag enough to get stuck in the long barrel. I never had that happen. In fact, they still have enough velocity to hit ALOT harder than my 1000FPS .22 pellet gun does. They punch through both sides of a steel fire extiguisher, the airgun only barely manages one side.

Shooting my Walther P22 next to my Marlin 60, there is a noticeable difference in the report. The P22 is a little screamer when shooting hypervelocity ammo.
