CCI Quiet...

[rugerjunkie]

Anyone have any luck with accuracy with this stuff? Took out the 77/22 and a new 18" barreled American and at 25 yards it shot patterns of 4"-5". Not very impressed.

It was the first time out with the American and it did shoot ragged holes at 25 yards with Mini-Mags and some new Winchester Super-X. The 77/22 has always been a good shooter but got the American as a beat around rifle and its on par with the 77 in accuracy. Neither one though cares for the quiet ammo which I was hoping to use for vermin control around the house.

The CCI Quiet .22 LR's is in the same family as their CB Shorts and Longs. All shoot at 710 fps. The shorts and longs use a 29 gr bullet while the Quiet's use a 40 gr bullet. I've shot the CB longs for about 40 years and love them! 1" at 25 yds in my Rem. 581. The beauty is that Mini Mags shoot to the exact POA as the longs, though the MM's shoot about 3/8" at that range.

I'm down to about 250 of the CB Longs and can't find any anywhere I have a brick of the Quiets waiting for another 581 due in tomorrow. I'm not expecting as good a performance with the heavier bullet. Range is everything! They'll drop like the stock market if Hillary got elected.

My point is that the Quiets seem like a short range affair. Try them at shorter ranges. If you're like me, anything less that great accuracy at 25 yds is dismal.

I'll forget about this thread in about a week when I get a chance to wring them out. In the meantime, try to get the CB Longs. Buy all you want and let me know if there's any left over

Well, I shot some at 50 yards, out of my Savage MkII bolt gun, which with standard velocity match ammo, will shoot under .5 MOA, and it shot a "pattern" at that range. Really had to hold up on my aim as well. I think the quiet is only rated at about 740 FPS. So, in the light of that, I am glad I have only like three or four boxes of the CCI Quiet.

I really don't feel as though CCI really intended it for anything beyond ten or so yards...mainly for quiet dispatch of troublesome animals and such.

 

[Mobuck]

We've used several boxes of CCI Quiet on the trapline. I (and my 22/45) prefer Remington C-Bee for both accuracy and bullet performance. For ranges over 15', I have much more confidence in the CCI Subsonic HP and Aguila Subsonic RN or HP. 1000 FPS is way better than 700-750 FPS and I don't think there's all that much diff between subsonic and HV out of a pistol barrel.

 

[rugerjunkie]

I can see where a 40 grain run that slow isnt going to stabilize. I'll have to try it in some other guns and try a few other types of ammo. Its no big deal...I was just messing around with some things and had to try them out.

 

[ClintV]

My 77-22 don't like em, but my 52c puts them in one ragged hole at 25 yards. The squirrels hate them out of that gun.

 

[Three50seven]

I've tried some through my Marlin 39A with decent results. Groups weren't as tight as with Mini-mags or SuperX, but still plenty accurate enough to dispatch yard pests and for trapline use.

 

[CraigC]

I have yet to bench test these but I've shot a bunch just plinking.

I've always figured a good 50yds out of the CB's.

Stability shouldn't be an issue at all.

I can see where it very well could be. At that low velocity the twist rate of a typical .22lr rifle may not be adequate to stabilize the 40 gr bullet.

 

[CraigC]

No. A 40gr .22 is not an overly long bullet, the SD is very low compared to other calibers using the same twist rate.

 

[22/45 Fan]

No. A 40gr .22 is not an overly long bullet, the SD is very low compared to other calibers using the same twist rate.

Yes but so is the velocity for those "quiet rounds" and the rotation rate may indeed be inadequate.

 

[Cholo]

I took 2 rifles to the range today, both Rem. model 581's. I had the barrel on one cut to 18" and crowned back in '76 or so. I recently bought another that still has the 24" bbl. Both are scoped with that beautiful old 3/4" Redfield. My pest control load is the CCI CB Longs. Out of the shorter bbl. the Longs snap loud enough for my neighbors to hear with their doors closed if everything was quiet, hence the newer one with the longer bbl. They're noticeably quieter with the 24" bbl. They shoot 1"@ 25 yds out of both guns, maybe a hair larger with the new 24" gun. I'd say the difference is because my old one had a trigger job and breaks like a glass rod at 3#'s and the new one about 6#'s measured. I need to have that corrected.

CCI Quiet: Quiet but louder than the 29 gr CB Longs. At 25 yds. they shot about 1"+ with both rifles. Nice! One thing surprised the hell out of me. They shot almost 2" higher at that range :shock:

Out of those 2 examples, the Quiets stabilized and shot as good as the CB Longs at 25 yds. I simply don't have enough Longs to have done more shooting, though I have a brick of the Quiets. I see them as 35 yds. at best when it comes to squirrels. The longs are about 1.5+" low at that range; I didn't test the Quiets.

If anyone sees the CB Longs for sale on the net, let me know. I need a couple of bricks. Love them! :mrgreen:

Prove it.

Otherwise, this is completely unfounded and a non-issue.

I don't have to "prove" anything, it was just a supposition based on several above reports of poor accuracy with these rounds in otherwise accurate rifles. I seemed like a reasonable explanation. What's your explanation?

Well, I have tested them, as noted above, but you failed to read what my experience was yesterday.

BTW: CCI has a bad habit of cranking out .22's that can't hit the sky if fired upwards. Riiight... :roll:

Relax, I wasn't attacking your integrity. Yeah, I read your experience with them but you seem to be the lucky exception based on the results of other posters above. I have no experience with these rounds and was only conjecturing an explanation for the highly variable results.

I've had poor results with low vel ammo in several rimfires. For those who doubt velocity matters here is one (of a bunch) of twist calculators. They don't go down to rimfire size and velocity but you can toggle the velocity number for any bullet and see the effect.

What we REALLY need is for Trump to get the Hearing Protection Act passed so we can shoot fast stuff quietly without having to jump thru all the ATF hoops and costs. If you haven't agitated your congressman and senator yet, you should.

Unless you know something about twist rates.

 

[22/45 Fan]

Unless you know something about twist rates.

OK, then you explain why the poor accuracy so many others have reported.

 

[CraigC]

I have no explanation because I haven't experienced it.

If a bullet is stabilized at 1000fps but not at 700fps, then the twist rate is marginal. We know for damned sure that 1-16" is NOT marginal for a 40gr .22LR.

There might be a problem but twist rate ain't it.

 

[WAYNO]

Often, individual guns are an island to themselves. If there's ammo that you know your gun wont shoot, then ya make other ammo choices. I imagine I'll get stomped on too, but velocity does affect RPM. So one gun, maybe a non-concentric bore/chamber, or really poor rifling, or a poor crown, might shoot okay with an optimum spin, but ya slow down the spin a little bit and that just might be the straw that breaks the camels back.

Other end of this spectrum...I have shot a bunch of the Aguila 60-gr .22 LR in multiple guns. Accuracy has never been an issue, and I've never seen evidence of key holes. Seems other folks really struggle with this ammo. Must be something wrong with my guns since they don't perform like others do.

I'm gonna throw out another thought. CCI ammo ain't always what it used to be. Don't automatically assume that you couldn't have a bad batch.

WAYNO.

 

[CraigC]

It's true that every rimfire is an entity unto itself. Few generalizations can be made about rimfire accuracy, except that better ammo typically shoots better and ammo that shoots poorly is not necessarily bad. Some guns just don't like some loads and there is no obvious reason for it.

.22LR target loads consist of a 40gr bullet at under 1100fps. Which translates to about 900fps out of a pistol. If a 40gr does fine at 900fps out of a pistol, it's not going to suddenly start tumbling at 700fps. If the twist rate was 1-24" or slower, there might be an issue but not at 1-16".

 

[Popakapoff]

My 22/45 shoot the quiet fine for taking out pests.

 

[Mobuck]

"OK, then you explain why the poor accuracy so many others have reported."
I'm not sure what/why there are "reports of poor accuracy". I shoot 2 or 3 brands/types of sub-sonic/reduced velocity ammo through factory barrels with top-notch accuracy.The POI may not coincide with standard/HV ammo but the accuracy is adequate to exceptional.
For use on varmints and small game, the Remington C-Bee is my first choice. It's accurate and has excellent on-target performance. CCI subsonic HP is #2 choice.
For absolute best accuracy(in my guns), Aguila subsonic is the first choice. It is excellent accuracy wise in both 10-22 and 22/45 and has proven quietest in the 1000 fps + category of any ammo I've tested.

 

[RUFFBIRD]

I use those CCI Quiets for shooting grouse out of the trees late in the season after it snows, so the bullet doesn't travel so far when I miss.... Kind of like using a wadcutter in .32 so it will destabilize fairly quickly, at least that my theory on it! 8) They have their place & close up, they are good. The birds don't even hear em comin... :lol:
