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. :confused:

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.
 
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?
 
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.
 
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.
