Thread: kick arse suppresor ?

Hi guys and girls, I am about to run out of super low velocity 22 ammo ( 770fps) and it looks like any more will be pretty hard to come by. I made the mistake of going into humping and bitching in palmy the other day to see if they had any or were going to get any in. Basically they replied with a No, No, No and given their attitude I decided any more talk would have been wasted so went out the door. I don't mind a trip to Welly but see guncity has almost no cci segmented very low velocity stuff either.

So, seeing as I have a metric shit ton of CCI subsonic 1050fps stuff, has anyone tried a very large suppressor to get the sound down to a similar level as the 770 fps stuff ?. The neighbours know I shoot possums, Starlings etc... but I am keen on them not hearing me actually shooting so like the super quite stuff.

I am shooting mainly out of my model 2 BRNO with a "normal" suppressor on but the cci stuff still makes a bit of a crack ( much to the excitement of the AOS as mentioned by me previously ).

Sorry for the overly long bleat

DPT with extra baffles

End of story

I tried a big long centrefire suppressor and it was good with subs but still cracked with supers....if you getting crack...you going supersonic. NO suppresser will fix that.

Oh I thought 1050 fps was still subsonic ?
When I say "crack" it's probably just noticeably louder than the 770fps stuff which sounds more like a air rifle level of noise

My new 22semi is ultra quiet running cci subs and a gunworks fat 22 suppressor, the bolt cycling is louder than any muzzle report

What would be the diameter of the suppressor Danny ? The one on my brno is maybe twice the thickness of the barrel and about 150ish mm. I have a slip on one for my 10/22 that is maybe twice the diameter so maybe I should try that one. I do like the look of the DPT ones though

Try a 223 supressor but muzzle forward as the effective volume seems greater than over barrel. I am using cci subs in my unique with it's reciprocating baffle system and get the occasional crack which makes me suspect that the stuff is borderline subsonic as a 25 inch barrel should slow it down anyhow.

Yeah, the CCI Quiet ammo is definitely quieter than other subsonic ammo. I have also tried Fiocchi Long Z (I think!), it is quieter than most at 850fps but still louder than the CCI segmented.

Apparently the first shot of a string is louder due to the "pop" of the oxygen inside the suppressor burning off.

This.

I just use my standard centrefire overbarrel DPT that i run on my 223's, i have tried it with a couple of extra 22 cal baffles on it on the 22lr with cci subs and you cannot really hear the shot, but you certainly hear the thud of the projectile hitting its small game target.

Every now and again i find that a random sub does give a crack, so obviously it's one that's just supersonic

Yeah CCI quiet is insane, I used it on my little badger with a DPT can until it got hard to get. All you could here was the click of the trigger and then the impact.

I have had the same issue with CCI subs as everyone above (going super), I honestly believe they are tuned to the american market where everyone is running semiautos, and end up going a little faster on non-semis. So I changed to Aquila subs and I've had a much better run with them (also found them more accurate than the quiets, the quiets used to suck over 25m).

35mm diameter by 150mm length muzzle forward

Aquila subs are definitely slower than cci subs, we chrono tested them can't remember exactly but there was a reasonable difference between them, the Aquila do run very dirty though

I'm currently running Winchester longZ but they are solid tip which gives the odd ricochet which made me thought I might try the cci quiet segmented.
I might have a look at a 223 suppressor with extra baffles, although I'm not rushing into anything yet. I still have 1/2 a box of the Winchester rounds left. I do like the click....thwack that the very low velocity stuff gives.

i use a dpt magnum on my M597 POS 22 as its a left over from another gun. Bloody quiet!!

Normally say yes but not sure if DPT makes a magnum in 22 line. The magnum centrefire is sublime for sound suppression. Friwi will conjure up a can for you.
