What do you guys think of Ruger's Silent-SR ISB for the

Also, according to their website, Reduces sound pressure levels of .22 LR to an average of 113.2 dB with standard velocity ammunition.

Would that be a decent reduction in noise level?

>>34472828
not really.
Would not be near movie quiet.
but would not need ear pro.
but it is a cool idea and a more compact package.

>>34472928
nigga it's .22, you basically don't need earpro to shoot it normally, im sure this would be fine.

>>34472928
Nothing gets near movie quiet
I remember reading somewhere that mics have a max dB level they can pick up and everything above that gets cut down to that max level.
Any Audio/Videofags on here that can verify?

>>34472961
it's true, but it really depends on what kind of mic because each mic has it's own set of characteristics. there can also be limiting in the recording software

Get a manual action and a can you can swap out if you want to bother with paper work.
Shoot that primer only stuff if you want a quiet 22 with out paper work.
If the HPA passes I'd be all over a take down, silenced 10/22 if it can cycle subs.

>>34472961
If you're talking relative to the volume of conversational voices you can get that with the right baffle design, or get close enough by using rubber gaskets.

>>34472828
109db is about as quiet as subsonic .22lr gets when measured at the muzzle. So yes that's a very good sound rating.

I'm assuming that the barrel is internally ported so that standard velocity ammo is subsonic.

>>34472961
>nothing gets near movie quiet
CCI Quiet or Aguila SSS through a 22"+ boltgun with a good screw-on can get pretty fucking close. Some of the testing I've seen is showing between 76 and 83dBa 3' from the muzzle, which is slightly louder than a good dish-washing machine or what most people have their TV's set to.

>>34473047
when i had a can on a 22 handgun it was pretty much movie quiet.
all you could hear was the action cycling, and the impact of the bullet
but that is still pretty loud.

>>34473007
I've worked over my 10/22 to where it reliably cycles any subsonic round other than CCI Quiet.

If the HPA passes I'm building a 10/22 dedicated around the Aguila 60gr SSS and using one of the Green Mountain 1:9 barrels. Due to the extra bullet mass those will actually cycle pretty much everything in stock configuration and some companies recommend using a recoil buffer with them.

>>34473120
60 grn subsonics.
that might actually make suppressed 22lr worth the hassle for something other than fun.

What is the difference between 10/22 and .22lr? Am I retarded?

>>34473181
10/22 is a gun made by ruger that shoots the 22lr bullet.

>>34473162
I use them a lot for silhouette shooting because they carry enough energy to knock the steel plates down past 150 yards.

Just be aware that a LOOOOOT of rifles don't shoot them for shit, they don't stabilize them properly. There's a reason a couple companies are offering 1:9 or 1:10 barrels for things like the CZ452 and 10/22 specifically for them.

With the right barrel they're pretty fucking accurate too. Will run neck and neck with Eley Club.

>>34473181
10/22 is a rifle. Specifically Ruger's model 10/22 semi-automatic rimfire rifle.

.22lr is a caliber. Specifically .22 long rifle. It is named as such to differentiate it from the several other .22cal rimfire rounds, the .22 short, .22 winchester rim fire, and .22 long.

Potentially depending on whether you bothered to look it up before asking and couldn't figure it out or not.

I have an integrally suppressed 10/22 nontakedown.

Happy to see Ruger offering factory options and would like to see it in a non takedown as well. I like that it is all stainless suppressor parts as well; .22 is filthy as you know.

>>34472942
don't listen to this guy
but with this rifle you should be fine without earpro

>>34473120
How did you do that? The only two I have right now, is the one that my dad gave to me and
the one my dad owed that I got after he passed. I have zero interest in modifying either...but since Im a sucker for stupid guns the model 21165 looks like something I could get behind...

>>34473181
10/22 is a rifle made by ruger. The ten comes from the 10 round rotary magazine. The twenty two is a caliber and comes from the, well, the caliber. LR stands for long rifle, there are 22 shorts, 22 longs and 22 long rifles and 22 win mags...just please dont ask how many different rounds can be fired out of a 357 mag revolver.

>>34473276
1. Ramped the back of the bolt for less effort in cocking and to lower the bolt mass slightly
2. Trimmed 1.5 coils off the guide rod spring for less effort in cocking
3. Scrubbed all the old paint and shit out of the inside of the receiver for less friction while cycling
Those promote the cycling of weak ammo and are things you can do to pretty much any model of semi-auto .22 rifle.

Other things I did:
>drill hole in rear of receiver so I can clean breech to muzzle
Lowers risk of crown damage and makes cleaning easier over-all
>installed recoil buffer
I also shoot high velocity rounds and the Aguila 60gr shit through it so I put one in to keep it from beating itself to death with them.

Total work took about an hour, but I have a bench grinder so if you're trying to ramp the bolt with a file it'll take a lot longer.

>>34473327
Welp, looks like I got another project on my hands.Thanks!

>>34473388
It's a pretty cool project and if you've never detail stripped one before you'll learn a lot about how and why your rifle works. Highly recommend doing it.

The recoil buffers cost $2.50 through any number of different sites, or you can make your own out of a chunk of delrin from Lowe's/Home Depot/Menard's for like 30 cents.

anything below about 122 is comfortable IMO. No ringing, ears don't feel weird, no negative effects whatsoever.

you're the retard in this case, actually

A friend of mine was shooting CCI Quiet through a lever action with a 20 inch barrel. It was movie-quiet. I've literally heard BB guns louder than that thing was.

That is quieter than an ar15 action closing (without firing)

>>34473750
Yeah it's not about comfort buddy. You're damaging your hearing long before it gets uncomfortable.

>>34474752
Good job proving yourself wrong? I'm going to assume that chart continues as it does and 115db is going to be about 10 minutes of exposure. Unless you have a belt fed .22 and you fire it for ten minutes straight you are not going to have a problem. Duration is nearly as important as the db level.

>>34473120

I wouldn't. IIRC they stopped making the SSS, along with the Colibri/Super Colibri.

I'm hoarding as much Colibri as I can get. But if HPA or SHUSH or whatever the fuck ever passes, I plan on getting a suppressor for my old bolt action single shot Stevens and use the no primer colibris in it. Be quieter than a silent fart I betcha

you wear ear pro when shooting .22? It's hardly any louder than my pellet gun. If you have hear issues cause .22, you're hearing issues lie deeper then that.

People itt are fucking literally retarded. Any impulse sound under 120 db is definitely safe. Stop being a fucking retard.

>If the variations in noise level involve maxima at intervals of 1 second or less, it is to be considered continuous.
According to OSHA, if you're shooting more than one round per second, you shouldn't shoot the Silent-SR ISB for more than half an hour a day without earpro.

>>34473007
I don't think the HPA will pass. I actually don't want it to pass. Suppressors need to be regulated in order to stop people from having an easy way to quietly murder people.

>>34472808
It's cool but costs more than the gun so it's too expensive for my tastes

>>34485524
If you're worried about criminals getting them, why not just require a form 4473 to buy one? It's not like there aren't other quiet, lethal weapons out there. That Kuklinski guy, the one with >200 kills, used shit like cyanide and a handheld crossbow. A weapon is only as deadly as the person using it.

Transients over ~110dB(spl) will damage your hearing permanently. The threshold for pain with transients is ~120dB(spl). That 10dB range is super dangerous because you don't feel pain but you are being damaged.

So how much more quiet is a bolt action .22 rifle with a can compared to a .22 semi auto with the same can?

>>34491552
Definitely at lesat a little, since there's no noise from the action cycling or gas escaping the ejection port.

>>34474752
this sort of chart is for CONSTANT exposure, not intermittent exposure.

>>34474752
The effects of impulsive noise exposure (gunshots) are different than steady noise exposure (machinery, aircraft, etc), so if anything you'd want even less time than this chart would suggest.

The reason being that your ears will adjust if continuously exposed, but impulsive noise can occur without warning. Even sounds in the ~100db range can cause hearing loss if they occur in an otherwise quiet environment.

so yeah wear earpro even for .22lr

>>34494261
If you know anything about over all volume and how two sound sources combine you would know that isn't true.

This happens every time k talks about sound.

>>34494853
I'm all ears, professional audiologist.
Enlighten us.

>>34495032
Audiologists know about ears, acousticians, and to some extend audio engineers know about how sound works.

So basically you would measure the two sound sources in dB(spl) which is a logarithmic scale, and convert to a linear scale before adding. This means that in order to make an appreciable change in the perceived noise level you would have to have another sound almost as loud or louder.

A better explanation with a calculator app here:
https://www.noisemeters.com/apps/db-calculator.asp

>>34495032
Also good pun.

>>34497731
There's a difference between the perceived noise level and the actual noise level, isn't there?
Surely from a hearing protection standpoint, not having an additional source of noise right next to your ear must help at least a little.

>>34500180
Nope, perceived is how it affects your ears mechanically.

Does the 10/22 takedown actually feel solid? I never held one, but I never gave it much thought because I assumed that a gun so easily separated from its action would probably feel cheap and bendy in use.

Bunch of slack-jawed faggots in this thread whining about .22lr. From age 8, I have been to the range almost weekly firing .223 and x39 from 16" barrels with no ear-pro. Been to many rock concerts standing next to the 8 foot speakers blaring in my ears and I'm 40 now with no EEEEE or hearing loss.

>>34502282
I have a takedown. It feels solid. Once the barrel is locked in, it's locked. It has it's own set of locking lugs, as well as a detent holding it in.

It comes with a bag to carry it in, as well as a Weaver rail if you want to mount optics. Overall, it's a good package for a take down .22 rifle. I'm really happy with mine.

>>34504805
Fuck man you got lucky. I have done factory work and construction (concrete cutting) since I was 13 with minimal hearing protection if any. Not to mention basement punks shows and guns. 21 now. I got the eeeeee and I'm hard hearing.
