peek-at Posted October 6, 2010 Report Share Posted October 6, 2010 (edited) Hi, I dont spend a lot of time cleaning my 22LR as I know a lot dont..... quick wipe down and a pull through with an oily swab now and again is good enough for me. However, I have had a few instances recently where I have taken a shot and the rifle has failed to fire with just the click of the firing pin. Upon inspecting the round it has clearly been struck as you can see the indent of the firing pin. The bolt is clean to look at and always gets a wipe down after a shoot and the extractor/holder gets a bit of a scrub with a toothbrush. (the wifes obviously) Is there an underlying cause to this ? could it be internal muck or is it more likely that the spring needs replacing? Am I overthinking and its just faulty rounds?................ (I use Eley subs) The rifle is probably a couple of years old now so should the spring be replaced anyway? If so, what about the extracor/holder ?........... is it best practice to change these too? I have looked on Youtube at the disassembly guide using a tyre valve so it looks simple enough. Do I need fancy solvents etc etc or can I just use my trusty gun oil and toothbrush? cheers shaun Edited October 6, 2010 by peek-at Quote Link to comment Share on other sites More sharing options...
Harnser Posted October 6, 2010 Report Share Posted October 6, 2010 Miss fires are not uncomman with the .22 rimfire . The primer material is spun into the case at the manufacuring stage and sometimes it dosent coat all of the base of the cartridge and will cause a miss fire if the striker hits a part of the case with no primer material . You may have poor batch of ammo that has this problem . If it happens again take miss fired round out and try it again , I bet it will go off . Dont think you need to replace firing pin unless it is striking on the light side . I have never changed my spring or pin in my rim fire and I have had it for many years .

snowz Posted October 6, 2010 Report Share Posted October 6, 2010 (edited) same as above, also had bad extraction from too much wax on the ammo if you want to clean your bolt for piece of mind i followed this video and cleaned mine Edited October 6, 2010 by snowz Quote Link to comment Share on other sites More sharing options...
Oxon88 Posted October 6, 2010 Report Share Posted October 6, 2010 When you had the mis-fires, did you check the rim of the casing to see if the firing pin had struck? Quote Link to comment Share on other sites More sharing options...

Shropshire_Lad Posted October 6, 2010 Report Share Posted October 6, 2010 Hi Shaun, as said give it a strip and clean, it won't hurt thats for sure. Could well be some duff rounds or a light strike if its gummed up. I've just put a Yodave striker spring in my CZ HMR and I have to say the strike dent is huge compared to the old spring, that said I had my first duff round within 6 shots of fitting it, the previous 1600 never a problem! atvb Paul.

Oxon88 Posted October 7, 2010 Report Share Posted October 7, 2010 Yes it had definitely struck and left an indent shaun I would say its a probably a dodgey round then. It would be worth cleaning the bolt as good practise. You may have a bad batch of ammo though! Quote Link to comment Share on other sites More sharing options...
peek-at Posted October 7, 2010 Author Report Share Posted October 7, 2010 Anyone got advice on products to use? (white sprit, toothbrush and gun oil or does it need more specialised stuff?) cheers Quote Link to comment Share on other sites More sharing options...
arjimlad Posted October 7, 2010 Report Share Posted October 7, 2010 I've sometimes used WD40 to blast out the nooks & crannies once the bolt is stripped, then relubed sparingly with normal mineral gun oil. I've also used a pipe cleaner to clean out the pin channel. Not an operation I perform very often though, but it's always fun to give everything a nice strip & polish in front of the TV of an evening.

Harnser Posted October 7, 2010 Report Share Posted October 7, 2010 If you dont fancy stripping the bolt down ,then soak the bolt overnight in carb cleaner . This will remove all the gunge . Then give a good blast with WD 40 and re oil . Harnser . Quote Link to comment Share on other sites More sharing options...
ollie Posted October 7, 2010 Report Share Posted October 7, 2010 I just dismantled my bolt and reassembled it. Very easy process but to be honest the bolt was very clean, the rifle is about 3 months old so not too much dirt in it. Quote Link to comment Share on other sites More sharing options...
peek-at Posted October 8, 2010 Author Report Share Posted October 8, 2010 I had some spare time this afternoon so I stripped the bolt down to give it a clean. Its a couple of years old and there was a small amount of muck in there which cleaned very easily with just my modified toothbrush, gun oil & pipecleaner to get into the firing pin channel. I read elsewhere that the factory springs can degrade and lose some of their power. I had a new factory spring spare anyway so I replaced it and after re-assemby I definitely noticed a more positive action from the firing pin. You can upgrade the springs to chrome silicon springs which I might do in the future. Thanks for the advice fellas shaun :look: Quote Link to comment Share on other sites More sharing options...
