Can someone tell me why CCI Quiet (40gn 710FPS) is louder than any other subsonic ammo I am using in my Dead Air Mask?
That’s odd.Can someone tell me why CCI Quiet (40gn 710FPS) is louder than any other subsonic ammo I am using in my Dead Air Mask?
I had same POI shift. But that’s expected with it being such a low velocity.I was shooting it out of a ruger 10/22 with a 16 inch barrel with a bolt locking device.
The POI on the stuff at 25 yards is about 3 inches below my other subsonic stuff like Federal, Gemtec and Aquila through my Dead Air Mask. It really is strange.
In the case of the CCI Quiet, it pops any time I shoot it. As for the Mask, grease does away with the first round pop but, despite all the hype about it, I too thought it was louder than I expected. It is compact though, and I can throw it in a ultrasonic cleaner so it does have its virtues.I’m a fan of Dead Air but the mask did not impress me like some of their other models. There is definitely a first round pop and it’s just not as quiet as expected.
I found this exactly true. CCI Standard Velocity is not huge difference, can be found everywhere and is cheap. I just ordered another couple thousand from BassPro.Love my mask, sounds really good. With light loads or really heavy bullets, you get more residual gas in a semi, more port pop when it cycles. Should be noticeably quieter in a bolt or holding the action closed in a semi. The CCI quiet semi auto(45gr@835fps) are the quietest out of most of my stuff, they cycle, they do have more port pop than SVs in a couple pistols. Standard velocity are my go-to, not much louder, and found everywhere.
The semi-auto quiets have more port pop than other subsonic rounds, but I think it is because it is using a very fast powder to help cycle the action, so the action opens faster than it would with a subsonic round that is using a (typically) slower burning powder. In particular on my Browning buck mark the semi-auto quiets are probably not hearing safe at all. Regular quiets are (but don't cycle the gun). In my 10/22 the semi-auto quiets are probably hearing safe, but are noticeably louder than regular quiets. They are a lot quieter than subsonic/standard velocity stuff.Love my mask, sounds really good.

I keep a welders glove on the bench so I don't start a Mrs. O'Leary's fire.Try the CCI 45gr “suppressor” ammo. Marketed for rifles, but I’ve used it in my SR22 (with the DA mask) and had very little POI shift (and quiet too!) I also use it in my 10/22 TD with a SBX barrel with excellent results! I prefer my switchback when I’m using a 16” barrel (silly quiet with SSS ammo, it’s a 1:9 barrel…with a bolt lock device….) On another note, you’ll love the paladin when you get it (built like a brick $hithouse….. I quickly lit off 60 rounds of 5.45 from a 8.3” barreled AR and it didnt even break a sweat (though I did burn a hole through one of those silencerco “hot pads” shops like to give out when I rested it on the bench….)
Maybe an out of spec batch? Did you chrono it, by any chance, or are the figures as given on the box?Can someone tell me why CCI Quiet (40gn 710FPS) is louder than any other subsonic ammo I am using in my Dead Air Mask?
You hit it right on the nose. I got the chance to run some over the Chrony yesterday and they went from 675 to 825.Maybe an out of spec batch? Did you chrono it, by any chance, or are the figures as given on the box?
