Thread: How to make my .22 quieter

Someone asked where to buy Elley? But I deleted the message accidentally. NZ Ammunition are the importers/distributors, but I don't think they sell directly to the public. I understand that they do sell directly so small bore indoor club and clay target club. I don't know about supply agreements with NZDA. If you are a member of a club, talk to your club management. Alternatively, GunCity Wellington has stocked it in the past, but like the tide, supply goes in an out.

That was me mate.

I ordered a second fibrous bush to fit the .22lr, at $18 it was cheaper than buying a second suppressor.

My guess is that CCI Subs HP is designed to cycle in semi-autos. it is therefore loaded close to the edge of sound speed. When you shoot semi you lose a bit of speed. I have shot thousands of CCI subs out of 10/22 and never had a supersonic one. One online report show they average 1020 FPS in 10/22 and less with suppressor. https://rimfirechannel.blogspot.com/...-grain-hp.html

Naturally when you shoot bolt action it will go faster. One online report show tested 10 shots, they all go over 1070 fps, 4 went over 1090 fps, 1 went over speed of sound of 1100 fps. https://squirrelhuntingjournal.com/c...p-ammo-review/

if you were shooting it in cold or high altitude from a bolt gun, it will likely to produce more supersonic shots. it is inherent in its design.

CCI Suppressor on the other hand lowers the speed further (1050 down to 970) so you are guaranteed to be subsonic even with bolt action. To ensure killing power they increase projectile weight from 40 to 45 gr. You pay more for it given that it has more lead and probably more powder.


One last point, my guess is that all subsonic 22LR ammo are more expensive to produce than supersonic ammo due to tighter tolerance required to keep speed within range. Too fast it becomes supersonic and too slow it will not kill game. With supersonic ammo they can be a bit more loose with the amount of powder and the weight of of the projectile. I bought a case of Aguila "superextra", 50% go subsonic and 50% go supersonic. The Aguila "subsonic" is about 20% more expensive, but looks to me to be the same ammo just slower.

I have shot thousands of Eley team, it and Match and Tenex are the fastest sub-sonic ammo I have shot yet i never had a supersonic one. They have tighter tolerance and they cost more.

jeez Hugh...I guess all the people over the last 40 years have been doing it wrong all this time with the likes of a manders suppressor.....
strange how we have had quiet results for thirtyfive of those and only in last few years are problems popping up....
strange how its been since winchester moved production from OZZIE to the states....
some of us have tried suppressors with MORE capacity than the DPT (WHICH ARE PLURRY GOOD SUPPRESSORS) and found the small old suppressors do just as good of job...
I would sooner use a slingshot and stones than darken the doorstep of the establishment you mention in last line...

Gidday Mickey, there is no right and wrong, there is only personal bias. Beauty is in the eye of the beholder. I, just like you, "would sooner use a slingshot and stones than darken the doorstep of the establishment, with the big GREEN buildings." Which illustrates perfectly that there is no right and wrong, only personnal bias. Shoot straight mate! Hugh

my 22 with the $1 bottle screwed on the end is just as quiet as my most expensive ($300) suppressor that fits the same gun

Only thing worse than a couple of young , dumb , full of cum dickheads punching each other is two geriatric dipshits waving their walking sticks at each other menacingly.

You two should give it a rest.....

some may be in a bag but im increasingly finding a lot of entities with it between the ears ala "shit for brains" and that includes on here.
the smartarse commets re the elderly are wearing a trifle thin too - be warned -one fucking day you lot will be in this position too!

Back on post.
Had a moderator that came with my 10/22 back about 94? One of the first stainless ones but just before the target model which made me spew as I would've goon for that.
Anyhoo this moderator which somehow went missing between leaving a bunch of stuff including my firearms was very effective.
I did have a slip on silent kill which some people rate but wasn't as good as others and it definitely wasn't as quiet as the other one I had.
Light alloy body with 3 sliding chamber about an inch or so long and a spring.
I reckon you could hear them shuffle forward when you fired. If you didn't stay on top of it cleaning wise they would get stuck.
Bit of a pain to get out and I had been know to actually fire a shot through it into a bundled up rag if it proved too troublesome.
It was still quite even when it was grubby.
Back in the day it was winchester subs or kilwell hushpower which I believe were the same.
Not a lot to pick from but they were good anyway.
Tried PMC stuff as I was a fan but they were a copper wash and a bit tough.
Suspect the same projectile as the Zappers and hollowpoint was for supersonic.
Didn't mushroom bugger all.
Remember a very brief play with Eley subs. Called scorpion back then?
They seemed to work just as well as the winchesters but no cheaper so didn't carry on with them
Surprisingly the old spring and washer types seemed to work pretty well even if the holes in the baffles were big enough to drive a truck through.
My 10/22 and moderator came through an agent from GC I believe.
If I could buy another suppressor like that one I'd be happy.
I've made a few but a lot of buggerising about and usually heavier than I'd like.
The ones for me have been an over barrel type so they don't stick out so far
Little blast chamber and some volume back over the barrel (sealed, gases only come out the end) with 3 K baffles seemed to work but not a lot quieter than others with flat baffles.
Really need to test them side by side properly.
Last one I did fo kotuku was a monocore but a very rough type.
Thin SS tube with a couple of tig spot welds holding the threaded rear and the monocore from white nylon (from work) with some slotted baffles drilled into it.
The mill shit out so had to finish it with the drill and a die grinder.
Like I said a bit rough.
Hate to say I was a bit too optomistic with the hole through the center and it was getting a baffle strike.
Kotuku ran the drill through it and problem solved.

smiffys wee unit does its job quite happily for me as do my guncity /manders suppressors-In fact ive never has an shot animal complain yet.silencer -removes all sound suppressor reduces level of sound-there is a difference subtle as it is

Another factor not yet touched on - Even if the bullet itself is travelling at just slightly less than the speed of sound, aka transonic, the air pushed aside may be momentarily forced to break the sound barrier. So bullets start to get quite noisey as they approach the sound barrier, its not a strict yes / no super/sub sonic thing.
