Is all .22LR subsonic in pistol?

[Arizona_Mike]

I played with my new 22 Sparrow SS for the second time comparing different loads by alternating in the magazine of my Ruger 22/45. I shot both semi-automatic and single shot (using my thumb on the back of the bolt). Aguila SuperExtra Subsonic 40gr was the quietest of the bunch, had less recoil, and did not functiom reliably for the first few rounds in the mag.

For Remington 22subsonic 38gr (powder coated bullets), CCI MaxiMag 36gr, and CCI Subsonic 40gr there was no difference in sound at all and all functioned well

The Remington stuff smelled great. The Aquila reaked of ammonia, the CCI Subsonic had a little ammonia smell, and very slight for the CCC Maxi Mag.

For 4" pistols as far as I can tell all of the "High Velocity" 36-40gr stuff is sub-sonic. But for 5-6" barrels I can hear that most are sub-sonic but some aren't as the cheap stuff isn't all that consistent.

In my 7.5" AR conversion "standard velocity" is sub-sonic while the cheap HV stuff seems to always "crack".

I'd think all the bulk 22 ammo (most of which seems to be around 1,200 fps) would lose enough velocity to be subsonic out of a pistol length barrel.

I shot a magazine thru a Ruger (one o' them lightweight, ray-gun looking things) and a Thunderbeast silencer (all titanium, sealed) the other day - Ammo was Winchester Expert, around 1,200 fps and it was plenty quiet.
Shot one round in the woods and you could hear the round traveling through the trees over what little noise the gun made.

I've got a few silencers currently in NFA jail, including the same unit you have.

I plan on shooting bulk stuff thru my pistols, but it may be borderline thru my 22 rifles, which is going to be the majority of my shooting thru a silencer.
I'm hoping some of the bulk stuff will be subsonic (during the summer?) as I hate to pay the prices they're asking for subsonic ammo!
I do see a couple of companies appear to have bricks of subsonic entering the market (catering to the silencer crowd?), but it's still higher than normal bulk 22.

BTW-have you considered anti-spatter spray to help in cleanup?
The stuff worked great when I pulled my apprentice welding hours (played with it a bit) - I picked up a 16 oz. can of Hobart @ Tractor Supply the other day for $8.99 - I plan on tearing my two 22 silencers apart and coating the guts liberally.

Try as I might, I could find only one person giving actual feedback after using the stuff - plenty of old posts asking about it, but I could find only one person that had followed through. He said his first two baffles (AAC) required a little elbow grease, but the rest of the silencer just wiped clean. He said he was going to coat liberally and let dry (ad before), but may give them another shot just before he used them next time.

Be careful with "anti-stick" compounds and a suppressor, crud breaking free and bouncing around could effectively create a baffle strike.

Safer to let it stick and soak the parts in penetrating oil before cleanup.

Interestingly, I do not notice first round pop but did have new supressor pop for the first 2 rounds (oil ignighting)?

The wet improvement is very small.

I fired a few shots of each at an appogee against my mountain backstop and heard a very slight whistle with one of the CCIs.

I was impressed by the lack of lead on my hands from the polymer covered Remington stuff. Does anyone know how well it shoots? It had the least offensive vapors of the bunch (you bget more blowback to the face with a supressor).

I've heard the complaints about this and the Sparrow, I've never noticed it either.

GemTech recommends a bit of something like Break-free in the can LID initially to make the carbon easier to remove. Not sure it matters with a take apart, non-boosted can like the Sparrow.

Unless you are some kind of CIA assassin I can't really see how a first round pop really matters at all.

I've got some old Remington GI "standard velocity" that is very clean and quiet, OTOH my experience with the current "polymer coated" Thunderbolt has been dismal in terms of barrel leading so I'd stopped buying before I got my first suppressor.

All of the different loads I tested with a chronograph & in Silencerco's lab with a Sparrow on my 22/45 were subsonic.

Seems like it was 8 or 9.

Suspect the CCL Stingers, the Winchester Xpediter and the Remington Yellow Jacket .22LR offerings would be supersonic out of a pistol.

Recent chrono testing I did with a Ruger MKII pistol w/5.5 inch barrel:

Lapua Standard Plus - 820.8 ft/sec

Eley Standard - 948.1 ft/sec

Winchester Dynapoint (WD22LRB) - 1014.3 ft/sec

Winchester M-22 (S22LRT) - 1019.1 ft/sec

I have a Huntertown Arms Guardian .22 suppressor, and have used it on a variety of hosts with a variety of ammunition. Here's what I've found:

Federal Champion Bulk (550 round cartons from Wally World) 1260fps will mostly stay subsonic from a 5" or shorter barrel, but occasional rounds will still go supersonic from my Nelson Custom 1911 .22LR conversion slide, GSG1911, and more frequently with S&W41 7" barrel. Less frequently from my SIG P228 4.5" conversion slide. Stays supersonic out of carbine length AR15 .22 upper and threaded 18" Marlin 795.

Blazer Bulk 1200fps always stays subsonic from a 5" barrel (and the SIG kit). Still goes supersonic in the rifles.

CCI Mini-Mag 1235fps mostly subsonic in my pistol length barrels, occasional supersonic especially in cold weather. Less frequent than the federal Bulk though. I'm guessing it is a little better standard deviation on the velocity. Supersonic from rifles.

CCI SV 1070fps always subsonic from pistols. Only very occasional supersonic from the Marlin 795, and only in cold weather.

CCI-Quiet 710fps always subsonic. Doesn't usually cycle semi-auto.

SK Rifle Match 1050fps haven't shot too much of it, but it has stayed subsonic in everything so far.

Is there a question in there?

Since the Title ends with a question mark, I'd say that's the question of the thread.

 

[Hometeached1]

Yeah the Thunderbolts are sub sonic (but they lead REALLY bad) out of my CRG 1911. Really want to get a can for it, it would be great for picking off tree rats while waiting for deer.

 

[DPris]

Still enough noise to spook deer.

Are you hunting deer with .22LR?

A few mag dumps of 230gr .45 out of my Glock through my AAC TiRant did not frighten away some nearby Coyotes. Think they were howling back at the ricochets

Mike

 

[Hometeached1]

No. Sorry, I should of been more specific. Use a .30-30 for deer, the .22LR is for the squirrels.

 

[DPris]

I may have misunderstood Home's message.
Thought he was referring to shooting the suppressed .22 at squirrels while waiting for deer to meander along, wasn't suggesting hunting deer with a .22 pistol.

I was saying the Sparrow on a 22/45 still makes enough noise to spook deer, it's far from Hollywood quiet.
Denis

 

[Hometeached1]

DPris, I was talking about shoot a squirrel while hunting for deer. Normally would not shoot one while hunting deer, but there are some that just keep taunting me. They get about 5-10yrds from my stand. I know it's me being impatient, but after sitting there for 3 hrs with them playing right in front of me is more than I can take.:banghead: and it's another excuse to pay the $200 "bribe".

 

[DPris]

That's the way I took your comment & why I said the sounds from the .22 would still be loud enough to spook a deer in the vicinity.

subsonic has to do only with velocity, breaking the sound barrier. suppressors
do just that suppress. you may want to try a pump .20/.25 cal pellet rifle.
