I've the same setup as you except with an rcc mod. Extremely accurate and quiet.

Eley subsonic, they are all I use. I've had cci and winchester go loud in the past but never eleys.

Try a different mod maybe. Depending too on your surroundings when shooting for example next to a farm building or a wall etc. an echoing effect can happen which can amplify any sound. It could be a bad box of ammo also?

It could be the batch of Eley subs are coming out supersonic if they are as loud as you are saying.

Hi,

I'd suggest trying a different sub through the same set up - that'll tell you if it's the set up, or ammo.

Assuming that's quiet enough, I'd then try and source a few Eley subs elsewhere, in case you've ended up with a bad batch.

Then I'd be changing the mod.

I'm expecting you to find the it's the batch of Eley that you've got - probably all bought from the same dealer, who may have received a consignment that aren't what they should be.

As an aside, I agree with you - much rather the old dark green box, but ditching them gave Eley the chance to roll out a few new shinny boxes of 22s, which no doubt produce a higher profit margin.

The old Eley subs used to be my 2nd choice, after Winis, for using through an old BRNO, but the Winis have really fallen off, so I'm in search of a new preferred sub myself, now.

Barrel length plays a big factor. My CZ 452 Lux with an Atec Wave is "Hollywood Quiet" A lot of that is down to the 24.8" barrel.

They are stretching the truth to sell you a silencer. But to a point where you only hear CLIK of a hammer drop to a PING! As your round hits a target less than a second later, is not very real. As no matter what there will be hot gases exiting the silence after the bullet which will still make some noise.Which, depending on where shot, maybe, or not louder than the maker's infomercial claims IOW did they do this demo out in an open field, a forest or an indoor range? Now, unless you are planning a hit on someone, it's about as relevant in reality as the noise difference as to whether you use whichever brand of tea bags if you are hunting or target shooting.IOW unless you break out the decibel meter and test it in a lab condition it's not going to be that much of a difference in practical terms for hunting

It probably can be done with an integrally suppressed firearm[Like the WW2 De Lesile carbine] A stubby ported barrel in a VAST expansion chamber and then a baffle set up with a wipe on the muzzle that the bullet must pierce IOW the entire silencer is the barrel. Very rare and expensive and virtually never seen in .22 and even then they need almost custom hand loads to be that quiet

As the load is now 2 grains lighter, yes it will have changed as maybe Eley has upped the powder charge to get it to an advertised FPS. But if it is still subsonic the difference in relevant noise on a decibel meter is probably something, but in practical field use its probably irrelevant. Unless you are getting a supersonic CRACK! once the round leaves the gun and passes an object on the way to the target, no silencer will sort out that crack. You have nothing to worry about. You could try running the silencer "Wet" IE and put some liquid, like gun oil, or even some have tried diesel, on the baffles and internals which works like an extra cooling agent for the gases of the shot. Just so long as you are not obstructing the path of the bullet, which as a liquid it won't do,it might quiet you can a few decibels more

from 3.00 onwards you'll hear what the .22 Eley 38g subs sound like with a moderator.

Just a note on the RCC mods they are extremely small which is grand and handy but the main purpose of a moderator is to slow the expanding gases from your muzzle , imho the RCC are too small to be efficient I have one I also have a sak and an atec 22 mods

My semi auto 22 is quiter on a decibel reader with the sak than the bolt gun with the RCC with the same ammo!

It's a mod problem they're just... Shite

And there I was giving out about winis.. 😉
