Thread: Ammo sticking in breech. .22 LR

    Ammo sticking in breech. .22 LR

    Hi Guys

    .22 LR Sako quad second day out new rifle straight out the box

    CCI segmented and eley subs

    new rifle de greased and cleaned before use and cleaned after initial sighting in

    after around 10 rounds, claw didn't retrieve spent shell, when shell removed a sluggish removal felt

    have exact same rifle and used LR and WMR in that one with no effect on anything.

    just removed barrel and scrubbed out, some residue found on initial run through, the two branded rounds have a light covering on but never had any problem.

    anyone know of a LR round that has no outer covering or better case to stop sticking.

    spent cases intact and no hard strikes found

    cleaned and run through barrel re assembled, flushed out the bolt, used spent shells all extracted perfectly Any ideas or experience of the same.

    cheers

    i have the same rifle. mine will always remove spent brass but will generally not remove unfired rounds.

    afaik the match barrel is to blame and if you send it back they open up the tolerance. there is also a fix whereby you shave a bit of metal off the extractor claw.

    My cz455 done this for ages and i just had to keep cleaning it. After around 50 rounds it was ok and never had a prob again that was with winnie subs. think it was just a combo of the new coated barrel and the waxy subs.

    Gmk have replaced the extractor claw for a new upgraded model with a finer claw Hopefully get it back for a test Friday
    Happy days again

    Got to say, praise where it is due. - GMK workshop Paul and Andy have been brilliant, they have been over the gun like a rash to sort it out.

    Hi artschool

    Did tolerance adjustment affect the accuracy ?

    did it effect the accuracy having the barrel opened up ?

    I had a tight chamber on a cz452, i found winchester and rws worked best as they a fraction smaller. But i still had to send it back to be reamed out as it would rarely extract a live round. When it came back it was perfect and would easy shoot 1/4 inch at 50 yards.

    I've had the same issue with a Finnfire, a good clean around the bolt face/extractor claw, plus a good doing with a chamber brush cured it.

    i never bothered as it was only unfired rounds so not worth the hassle.
