Suppressed 22lr
Alright I'm brand new to the suppressor world. So I just got my approved form 1 and solvent trap. Made a suppressor for 22lr.
When I use it in my 15-22 it reduces db to bearable without ear protection. But when I use it with my 22lr pistol it's almost movie like quiet.
Are rifles just gonna be louder even though it's same caliber?
Thanks for any help/feedback

I suspect the crack you are hearing from the rifle is the bullet exceeding the speed of sound - it's going faster than from a handgun. No suppressor can muffle the sonic crack of the bullet.
The velocity of the bullet from the handgun is not exceeding the speed of sound, so the suppressor is just doing its job of muffling the sound of the discharge. And it's quieter than the rifle.

Agree ^^^^^^^ with the above.
If your are shooting HV ammo then what PALADIN said is probably what's happening. Try some standard velocity ammo and see if you can tell a difference in the sound from the rifle.

Ok so I just shot some cci standard velocity 1070 fps couldn't really tell a difference. I have some cci quiet 740fps now that was quiet. What is subsonic for 22lr?

Standard velocity .22LR is usually subsonic (less than 1125 fps). So if you are still getting the "crack" with the std velocity ammo, then I have no more answers.

Std. velocity doesn't necessarily mean subsonic. It just means not high velocity.

1070 fps is close enough to speed of sound (1125 fps) that the bullet might be leaving the muzzle of the gun at supersonic speeds. Depending on how the manufacturer rated the ammo, you could be well above 1125 fps with your rifle.
Even with bigger calibers, which are presumably made with closer quality control, there can be more than 5% variance to the specified velocity (see some of Paul Harrell's videos on youtube).
If you can tell the difference with the 740 fps ammo, then your suppressor is doing its job.

Run sub-sonic ammo out of your 15-22 with the suppressor and all you will hear is the bolt operating when you pull the trigger..

I shoot sub-sonic or suppressor specific ammo exclusively in my Ruger 10/22 LITE with suppressor. About all I can hear is the bolt slapping inside the receiver and the bullet striking the target. The ammo still operates the action just fine.
CCI Quiet ammo is too under powered to operate semi-auto pistols or rifles.

CCI Standard Velocity tends to be consistently sub-sonic in my 10/22's and in my Colt/Umirex AR-22 with 20 inch barrel.I tried Remington's Sub-sonic branded ammo and about every 2nd or 3rd shot out of the AR-22 would be super sonic. Speed of sound will vary depending on elevation, air pressure and the ammo speed will vary with the above and temperature.

Years ago Hogue and Ruger worked on a project the called the "Alligator" it had a 1" barrel that was integrally suppressed, had the full rubber stock. They used the bolt action Ruger .22, with subsonic ammo it was the closest thing to the "pffft" you hear in the movies. We shot it into wet phone books in the gun shop, people in the next room did not notice. Bolt actions or single shots are the quietest, with a semi auto you have the noise of the action itself to deal with, kind of a "clack, clack, clack." I've been messing around with suppressors for years, mostly .40 and .45, the .40 is difficult to make quiet without using 180grn bullets, the .45 is fairly easy. The .45 sounds like you stomped your foot on concrete. You can make them real quiet by squirting white lithium grease into the inlet of the can, mounting it on your pistol and shooting, very messy but quiet...you can also stick it into a bucket of water, take it out and shoot, also very quiet but messy. If you needed to make one shot as quiet as possible using grease would be the way to go, each successive shot get louder, by three your back to normal suppressed.

I shoot CCI .22 Short SV in rifles, the noise level is slightly more than from a BB gun. No suppressor needed. In my Remington 550-1 it even functions the semiauto action.

What solvent trap did you use and how long did it take for the stamp to get approved?

Got the quietbore 22lr aluminum. Took a month for both form 1 and trap. Perfect timing as the form 1 was approved before I got the trap.

While I was shooting a 25 rounds mag there were a few subsonic but not all. Looks like the fps listed is a suggestion per se

Most manufacturers are going to list rifle velocities because they are higher.
Buy subsonic ammo. End of story.

Standard velocity .22LR will usually be supersonic out of
rifle barrel, and subsonic out of handgun.

Hmm you've given me a project. It won't cycle my Tac-Sol w/o the can, but just might with that added backpressure...

I shoot my 15-22 suppressed with an GSL Woodland suppressor.
The ammo I use is CCI Suppressor ammo. It works very well and is what I prefer. The CCI ammo is 45 grain weight and has a velocity of 970 FPS.
Try it, if you can find it now, and see what you think.

Maybe.
Don't recall if I've tried mine without the can. I know CCI CB
Short and Long wouldn't cycle the 10-22, before I got the can.

Been there, done that, with several friends' rifles. If you shoot from a cement floor like at ranges then you'll hear the brass tinkling when it hits the ground. But that's about all you'll hear.
But sure, high velocity rounds will crack the sound barrier and you'll hear them coming out of a rifle but not from a suppressed handgun.

Not a "ported at 1", ala MP5SD?
I believe the quietness claim--unlike most of the "all I hear is the
bullet hitting the backstop" allegations. Only downside would be
velocity would be...rather tepid!

The velocity or speed of sound is 748 feet per second. Super sonic is 1150 feet per second.

Actually, the speed of sound varies with temperature*. You'd
be pretty hard pressed to get cold enough to slow it down to
748 f/s. Any speed that's faster than the speed of sound,
is supersonic (e.g. 1272 f/s at 99*, or 1800 f/s, 2750 f/s,
etc---all are 'supersonic').

*and altitude and probably humidity, too.

I use Winchester Super X subsonic and Remington subsonic. Both cycle well, both are quiet, both are accurate.
Not "movie quiet" but then my pistol isn't either. Quiet enough that I've used it for pest control in an urban setting.

I run CCI subsonic with a Gemtech G5-22 can and you just hear bolt cycle noise and bullet hitting steel.

Here's a link to an experiment I did, some years back.
My suppressor is usually mounted on my PS90, loaded with subsonic ammunition. While louder than .22 caliber, at least I won't suffer hearing damage if I have to use it.

CCI CB 22 Longs when fired from a rifle are so quiet that the bullet striking the target is louder than the report.
From a revolver it is about as loud as a hand clap.
No tax stamp needed.

Anybody claiming "movie quiet" needs a consult with an
audiologist.

True, and only a small step up from a pellet gun, in
power & range.

I'm gonna have to call BS on this one. CCI Quiet might cycle a bolt on occasion, but experience shows it does not work "just fine" in most semi autos.

CCI quiet will not reliably cycle any of my semi-auto .22s
In my experience, CCI standard velocity remains subsonic out of my semis (pistol and rifle), and reliably functions in them. It's just as quiet as any of the fancy 'suppressor' ammo I've experimented with.
One difference with a rifle as opposed to a pistol: the action on the rifle is a lot closer to your ears when firing it, so the gun will seem louder to the shooter. The real test is to listen 10-15 feet away away from the shooter to remove those variables.
