cci quiet not going into breach

[ARGH]

wondering if anyone has success with feeding cci quiet ammo in their mp15-22. i got a box but most of them appear to jam in the breach allowing a centimeter of space when bolt closes. gun obviously does not fire at this point.

it seems like the breach is a tad too narrow. the gun is still quite new so maybe the the breach will open up just enough when it breaks in?

i understand that these may not always cycle the bolt but surprised about jamming in the breach. high velocity rounds feed just fine. also, the aquila colibri powderless also enter breach ok, of course those wont cycle the bolt as they are just primer.

Most likely, your 15-22's chamber is dirty. If you have been shooting the Colibri in your rifle, that is the problem ... Unburned powder and powder debris has filled the forward end of the chamber.

Both of the rounds you mentioned are for bolt actions, not semi-autos. Shooting them in a 15-22 is a poor practice, in my opinion.

BTW, if the breach ever opened up, there would be something seriously wrong with the steel in the barrel.

i did not realize that the primer would foul up the breach so quickly, shot about 50 rounds of collibru before trying the quiet. i will clean and see if it works this time.

Quit shooting that stuff in your 15-22. And use a brass brush on the chamber, not just a BoreSnake. The primer residue is probably baked into the chamber by now.

I only use the quiet and colibri in my .22 pump. No way id run that stuff through any of my semi-autos. If u want to shoot it, id advise finding u something else to shoot it from.

 

[ARGH]

you are right. the colibri indeed fouled the chamber. i am quite surprised as only about 50 rounds were fired. i used some hoppes solvent and brass brush and now the rounds seat in the breach much more easily like before.

i'll continue using the cci quiet and do a thorugh brush clean after each event.

i have to add that the cci quiets are so quiet that almost no ear protection is needed, even shooting them in your basement. they went through a 2x4 stud. the colibri did not even come close.

Shooting in your basement without a proper metal bullet trap is a bad idea. I hope you are using one.

i agree

My 15-22 is brand new also. Cleaned & lubed properly before very first use, and after every use since then. From day one, it did not like the CCI QUIET-22 LR ammo. Maybe fire 1 for every 10 attempts, mostly resulting into stove pipes... jus sayin

 

[Majorlk]

Make sure you are not over lubing, especially the BCG. all that is necessary is a drop of CLP or similar on the top and bottom of each bolt rail. No lube is necessary on the bolt body itself except to, at most, wipe it with a CLP-dampened rag.

There should be NO wet lube in the firing pin channel. It should be totally dry with, at most, some DRY graphite.

A single drop of CLP on the bolt latch, the hammer pin and the trigger pin is all the additional lube needed.

Your problem is typical of over lubing, especially the BGC.

Not sure about the OP, but I am not one to over lube. My rifle loves Winchester Super-X the most I believe. The federal bulk isn't bad, but not as good as the WS-X or the CCI Mini Mags. I do tend to have my M-4 a little more on the well lubed side, but not to the point to where liquid is spraying out of it.

I would suggest trying the Winchester Super-X or the CCI mini mags, and post the results later. By chance is your 15-22 a model # 811030 ?

The other major problem SM, is CCI Quiet has a velocity of only 710 fps. This is at least 250 fps too slow to cycle the action of a semi-auto. No wonder you are having constant stovepipes. With the exception of Olympic match guns, semi-autos need at least 950-1,000 fps to cycle.

I believe the manual also states not to use any sub sonic ammo in these rifles, but I have been "told" the manual is outdated, and a lot of the non recommended ammo, would be ok. My buddy has a 15-22 he purchased after I did, and it came with the threaded barrel. He has no problem using the CCI quiets. All I can say is these rifles are individuals. Some can simply shoot what others can't.

Does his rifle reliably cycle (extract empty, reset hammer, feed new round) the quiets?

Very unlikely ...

Odds are stovepipes are a common, if not every time, occurrence unless the bolt's recoil spring has been altered.

That's what I was thinking. Light enough hammer and recoil springs to allow the trigger to reset and avoid stovepipes probably won't have enough power to strip a new round and return to battery. It's a delicate balance that I haven't been able to find, even using a lighter bolt assembly from a 15-22P.
