You'll get the sonic crack from high velocity ammo TS. For Hollywood quiet nothing beats a suppressed bolt action ,22 rimfire with standard velocity ammo. Depending on where you're located high altitude/low temperature can make even some supposedly standard velocity cartridges go sonic.

Have fun with it when you get it. Cans are a hoot 🤠

I think one thing with supposed "Suppressor" ammo is the idea that it won't foul the innerds of the can quite as much. Some rimfire ammo generates a giant amount of residue. Hopefully you have a unit that's easy to disassemble and clean.

Subsonic ammo is really fun in a can, but the normal HV stuff still makes only a fraction of the normal racket.

 

If your host is a pistol most 22lr ammo stays subsonic through the short barrels. I like CCI SV in my suppressed rifles and pistols. Good luck with yours, they are a blast.

 

HK MP5 22 pistol & M&P15-22 rifle will be what I'm running

 

The level of "quiet" is related to the actual velocity, the suppressor, and the barrel it is shot from. I have a couple different ammos that are very quiet thru my T1x, but still have a little noise thru my MTR with its noticeably tighter chamber. Any ammo that is real close to 1100 fps will be borderline. Quiet in the Tikka and a little "pop" out of the CZ. That's part of the fun factor - finding the ammo with low noise and great results. Makes shooting that much more fun. Subtle changes in the weapon (action screw torque, support, hold, and more) as well as the shooter's technique will make a very noticeable difference. Grab several different ammos and have fun.

 

CCI makes Subsonic Polymer Coated .22LR. They also make SV polymer coated twice a year. For Independence Day they make Red, White and Blue. For Christmas they make Green and Red.

Doesn't matter. All of them will reduce leading on your baffles in my experience. You still have the carbon build up to maintain, but nor more picking out chunks of lead.

 

More info on CCI Clean-22 with a polymer coated bullet (as mentioned above).

CCI Clean-22 .22 LR Ammo - Shooting Times

The CCI Clean-22 .22 LR ammunition features an exclusive polymer bullet coating that is similar to the coating used on sister company Federal's Syntech centerfire ammunition.

CCI also has "CCI Suppressor" 45gr .22LR designed for suppressor use.

 

Rotatory tumbler with dawn dish liquid and stainless steel pins beat shooting crap ammo just because it's poly coated, ymmv, six hours of tumbling check and see where you're at.

 

Except that tumbling my aluminum baffles will destroy them.

 

More fouling from bulk high-velocity as others have said, but no worries otherwise.

When I really want to make a statement, I shoot CCI Quiets thorough my suppressor - at that point, the only two things I hear are the firing pin strike and the bullet impact downrange.

The other think is that from a 4" barrel Ruger MkII pistol, all high-velocity including 36gr are subsonic, which is a nice option to have - but considerably more fouling than SV of course.

 

That's one thing I like about my Sparrow - it's pretty robust. I usually clean it after about 400-500 rounds and it's not difficult. Went over 1000 once and it took longer, but still not too bad. I've seen quite a few comments about "first round pop" with the Sparrow and, yes it does. Doesn't bother me. It's a high quality, well made can that will last a long time. YMMV.

 

I have an old .22 suppressor that is sealed and all aluminum, bought it before I knew what I was doing...it can be cleaned but nothing like my Dead Air Mask, you learn as you go.

 

Yes Cans/Silencers/Sound moderators are very very addictive, over here UK they're pretty easy to get and are not restricted, some ammo will foul up the can quite fast when using a short barrel experiment to see what works best, I had a 12 inch barrelled 10/22 that would sound like someone had poured sand into the mod after a few hundred rounds, Eley was particularly bad for this,
But any standard velocity ammo will be very quiet indeed,


I've had a .223 bolt action with a Reflex over the barrel suppressor that was great fun, it made a noise like a scaffold pole being pinged with a hammer!

If only I could afford it I would love to get a Delsie Carbine in .45ACP

 

With my 22 pistols I have been shooting a ton of federal auto match. Stays subsonic in the pistol and to my ears the quietest out of the bulk stuff. And my local Walmart seem to have plenty of it a little over six cents a round so I don't have to dip into my stash.
For the 22 rifles been shooting Norma Tac and CCI standards.
But if I want to impress someone who has never heard a silencer I'll load up the CCI or AE 45g suppressor ammo or Aquila subs

 

Any .22 suppressor is going to get dirty...same for your firearm as blowback gasses don't escape as quickly. A good thing is that there is an increase in blowback energy. The bad thing is increased debris. I have not found anything better than dropping my Sparrow parts in CLR. Yes it damages the finish a bit but I don't care. The lead and powder just melt off. I have not seen any damage to any of the metal and the finish dulling is minimal. I also spray the guts with welding anti spatter prior to . Want to eliminate that first round pop just use a little water down the tube....won't hurt anything. Mine has O rings in it also so you might stock up on a box of them and change them out when cleaning time rolls around. Yeah, suppressors are very nice. Too bad there are so many hurtles to jump. 1917

 

I shoot the CCI 45 grain suppressor round in my rifles. All you hear is the click of the firing pin and a plop down range. The 45 grain suppressor rounds are hard to come by but I see that Target Sports has the Federal version in 45 grains for sale.

Here's a tip to making the cleanup on your suppressor baffles easier. Give them the silicone oil treatment.

The baffles in the attached photos are on their third cleaning now since I have treated them. I didn't keep an accurate count but I think I put about 500 rounds through this suppressor on my Savage rifle before this latest cleaning.

For the cleanup, I just used paper towels, scraps of cloth cut into patches and an awl to force the material into the tight spaces of the baffles. Basically, I just wiped everything clean.

I know it's hard to believe but it really is that easy cleaning this suppressor.

After cleaning, I put a very liberal amount of CLP on everything and a little RIG grease on the threads of the end caps. Some people may disagree with how much oil I put on the baffles and inside the tube after cleaning, but I believe that this helps to keep the fouling soft. This makes the cleanup easier.

Again, the suppressor is dripping wet with oil on the inside when it's reattached to the rifle.

Here is the link to the video on treating the baffles with silicone oil. You can fast forward to 3:50 where he starts to explain the process, which isn't difficult. At about 9:00 is where he gets down to actually doing it.

Basically bake the parts at 300 degrees for 20 minutes then put in the oil overnight. In the morning, remove the baffles and reassemble the suppressor.

How to Keep Suppressor/Silencer Clean w/Silicone Coating

I decided to get the pure silicone oil instead of the DOT 5 brake fluid.

I almost forgot; I shoot the CCI 45 grain rounds in two bolt action rifles that are quieter than a mouse fart. In the S&W M&P 15-22 all you hear is the clickety-clack of the action cycling.

 

OP asked about ammo. I much prefer standard velocity rounds for both pistol and rifle. People are correct that HV stays subsonic out of short barrels, but SV is still quieter. I'm a very high volume shooter, so I avoid specialty (expensive) ammo. I've found that Aguila and Armscor SV are both supersonic from my rifle, so are relegated to pistols. As a dedicated plinker, I really like Geco Rifle, Gecko Match, CCI SV, and lately Norma TAC-22 for suppressed shooting. I don't find shooting little holes in paper to be very interesting.

 

I like the sound of suppressed bolt actions with ammo like CCI SV or Norma, but both my own experience and objective measures showing sound levels typically in the 118 to 120 db range suppressed (very rarely 115 db and often as high as the higher 120s) convince me that they're still not quiet enough to run without some ear pro. I too have a can in prison but I no longer believe people who say no hearing protection is needed with subsonic ammo and a good can. I've heard several rifles with well-known cans both in outdoor and indoor conditions, and though they were much quieter than other guns, none of them seemed hearing safe to me.

 

100%. I always wear ear pro when shooting suppressed .22LR. Any ammo. Cans do let you get by with lighter ear pro. My fave:

 

It does make a difference in sound suppression when you match the length of the barrel with the length of the suppressor.

Those of you that have a suppressors that are one length will find they work better,with the same ammo, with the right length barrel.



For the first round crack with HV ammo, Dip your can in a glass of water before the first shot.

Dip it, let it drain, then shoot it. I shoot hyper velocitys 50 and 100 yds at exploding targets. It has to hit the target at over 1200 to set it off.

For an example, My can breaks down into three configurations. Here are the test results they did with the different lengths and weapons.

Sound Pressure Level ***
Full length 6.75"Configuration (best for short barrel applications and velocities over 1500FPS)

• 6" Buckmark Pistol
  • Standard Velocity 22LR: 121dB

• 16" Ruger 10/22
  • Standard Velocity 22LR: 120dB
  • Subsonic 22LR: 116dB
• 18" Ruger RPR 17HMR
  • Standard Velocity (2400FPS) 17HMR: 126dB

2/3 Mid length 4.5"Configuration (best for barrel lengths over 10" and velocities under 1500FPS)

• 6" Buckmark Pistol
  • Subsonic 22LR: 124dB
• 16" Ruger 10/22
  • Subsonic 22LR: 113dB

1/3 Covert length 2.25"Configuration (optimized for use with water or gel, velocities under 1500FPS on the shortest barrel possible)

For a real smile, shoot CCI Quiet out of a bolt action suppressed gun. The regular load is 710fps and won’t cycle a semi auto. There is supposedly a version of CCI Quiet running 835fps that will cycle a semi auto but I’ve never shot it.
Anyway, all I hear when I shoot the Quiet suppressed is the click of the firing pin and a hit somewhere down range. Everyone always thinks it’s a misfire!

 

I have a 22 suppressor in jail and am wondering if I'll be fine shooting the usual high velocity or standard velocity 22LR ammo.
CCI, Thunderbolt, Federal bulk pack, Winchester bulk pack, etc

I have had some success with Gemtech Silencer Subsonic 42gr rated at 1,020fps (box). It claims to be cleaner than most ammo.

I have tested boxes of 50 through each of my three non-suppressor CZ455's. Each rifle reflected 60~70fps Extreme Spread and Standard Deviation of about 16fps, with speeds from 1,006 to 1,060fps. I noted that the ammo is indeed cleaner than most😁.

Gemtech is based in Boise ID, which suggests a relationship with CCI (Cascade Cartridge International) based in Lewiston ID.

 

My cans are still in jail, but just ordered some CCI Quiet 45gr for semi-auto

 

What's the consensus on CCI Clean-22? I switched to CCI because the ammo seems cleaner, though I haven't explored Norma or Eley. Is Clean-22 actually cleaner than Quiet-22 or other subsonic ammo?

 

I think it’s nice stuff and shoots great but I’d just as soon shoot CCI Standard and save the money. CCI Standard is a subsonic load as well. That said, I’d have no issue grabbing any version of the Clean-22 if it was on sale.

When breaking down a suppressor to clean it, any load will foul the baffles if you shooters enough. There are definitely dirtier options but CCI is always decent for me.

 

I only run CCI standard for canned guns

 

i shoot suppressed often and I will shoot ammo that has a velocity of 1070 which is below the speed of sound. Such as CCI Target.

 

Depending on the rifle; CCI SV, CCI 45 grain suppressor, Norma TAC-22, Lapua Midas +

Depending on the pistol; CCI SV, Federal 36 Grain, Federal Auto-Match

 

About the only .22 ammo I've bought the last few years has been sub sonic specifically for use in suppressors. One "dark horse" load that I've really liked is Eley Contact, 42 grain...very consistent and quiet.

I bought mine about 2 years ago? It was under $5/50...Higher now unfortunately....
