Cooey 64B jamming

Hi All

I have a Cooey 64B that jams after shots while ejecting shells. I received a Lakefield 64B guide to disassembly and it says not to oil the firearm as it will inhibit operation. So, do I just clean the action really well and leave it dry? Is this ok?

Thanks and I hope this is the right spot for this thread...

Dry graphite film spray works on my 10/22 and keeps it from gumming up like oil would. 22's operate by blowback operation, and that spits a lot of powder residue back into the action. I used to have a 64b and when I cleaned it, I got a lot of dirt out of the action, including what looked like small brass chips. I guess the violent opening of the action tears little bits of brass of the cases.
 
Thanks guys. @Grizzleypeg, that's exactly the crap that I saw in the end of the action tube. I'll clean the oil out and maybe use some brake cleaner to dry it out nicely. Is that acceptable or will it corrode the parts?
 
Brake parts cleaner itself shouldn't cause corrosion. It's just a variety of fast drying solvents that shouldn't interact with metals. Removing all oil from steel parts (like the bolt) could make it more susceptable to moisture induced corrosion though. I haven't seen any problems with my 10/22 bolt rusting, but I haven't had it out in the rain or brought it in after extreme cold. I don't have the 64b anymore, but after cleaning, it shot reliably. It's not uncommon for semi auto 22's to have a favorite ammunition that they function more reliably with. But you can be fooled if the gun is dirty and the bolt moves with a gritty feel.
 
I would remove and clean out the extractor.
I used to use dry graphite lube all the time in my semi auto 22's but read somewhere that is it corrorsive to certain types of metals (aluminum I think...not sure)....so I've stopped using it.

Change your ammo
Try stingers see if it still jams
 
WOOHOO

I adore my 64's...all of 'em (even those I parted company with)

You have a fine semi-.22! Get used to cleaning it regularly (for me, every 500-1000 rds...less if thunderbolts are used)

-(as stated) Don't twist your barrel out. Some of them are very gummed, and may require persuasion. I tap with hardwood (hold barrel vertical, tap receiver with wood), but have used the bolt itself to dislodge (remove barrel retaining clip, pull bolt back and slap the barrel outta there)
- Clean thoroughly with your favourite solvent (I go back n' forth between "real" gun solvents, and brake cleaner...no definitive answer there. Experiment on your own)
-Run it dry!!!! Neat they added THAT to a manual. I have had only grief with lubricants, be they dry, or wet! I do oil for rust prevention, knowing it won't be in use. I also feel silly suggesting metal on metal be used with no lubrication. It works though. (for me about 25 years)
-Try different ammo...this is a tricky thing. Mine won't eat Winchester (where respected CGN'ers will) ammo. Mine loves Fed Champion 525 bulk (where respected CGN'ers won't) CCI (anything not CB) Blasers, minimags etc. Mine will cycle Remington Thunderbolts, and sub-sonics...it's filthy stuff though.
-ENJOY!!!!!

Fun .22's. In production for 50+ years, and still made today. That must mean something!

I do adore my 64's!
 
I would suggest rather than running it dry, use a lubricant which DOESN'T bake itself into carbon, like BreakFree CLP. Yes, clean it now, and shoot it WET, and you will find cleanup to be sooooooo much easier afterwards.

3 posts in a row...some kind of record for me.

I'll have to concur...with minimags/stingers, I n'er suffered a single jam. They were too pricey a soloution for me though. I HAD to use them for the first couple of years I owned mine. An ol'timer put me straight on running it dry. Much nicer to own n' operate knowing this.

You can extend the 500-1000 mark just by flushing action with brake-cleaner and cycling it...good if you're "out", and the thing starts to embarrass you by jamming/light straikes/FTF/FTE.

It's not that it bakes into carbon (lol I've tried to shoot that much). .22 ammo is filthy (some less so) ammo. As previously stated [not by me] blowback operation allows for lots of filth in action/chamber. Filth sticks to anything wet. For me, even dry lubes too...gunky-filthly-mungy mess in 10 shots instead of 500-1000.

I hate suggesting dry metal-on-metal...I change my oil in everything else. My experience suggests this is the best way to treat your 64.
 
I learned through trial and error on my 64Bs that I need to leave it dry after a good cleaning. They would stick horribly if left "normally" lubed. I have yet to try graphite as a friction reducer, but am willing to try.
 
I'm going to try an experiment with dry film graphite on aluminum. I have both anodized and bare aluminum in the garage. I spray some on and set it on a shelf. I'll report back next winter. I suspect graphite may increase corrosion because it may attract moisture, but I am not sure how dramatic this effect is. graphite is a form of carbon, and I suspect powder residue is similar, but even more corrosive. That said, I don't find powder residue to cause rust or oxidation that is noticeable.
 
From the below link in wikipedia:
http://en.wikipedia.org/wiki/Graphite


"The use of graphite is limited by its tendency to facilitate pitting corrosion in some stainless steel,[13][14] and to promote galvanic corrosion between dissimilar metals (due to its electrical conductivity). It is also corrosive to aluminium in the presence of moisture. For this reason, the US Air Force banned its use as a lubricant in aluminium aircraft,[15] and discouraged its use in aluminium-containing automatic weapons.[16] Even graphite pencil marks on aluminium parts may facilitate corrosion"
 
I've also tried several different ways to keep my 64a from jamming, fte'ing etc. What's been the most consistent method has been using the RemDriLube spray. It claims to leave a teflon coating, and it does seem to dry after using it.
 
WD40 is what I use to clean and lube. Works fine for my Winchester 64.

These actions don't like to get dirty. 50 shots and spray the crap out. Then go another 50.

Ha Ha!!! Same with mine there, Camster! My old girl that I asked everbopdy on here how to take apart and clean a few weeks ago on here is now running like a champ!! And she absolutely despises Winchester ammo ! ! ! ! Thats ok, because I found out that she gobbles Blazer and is quite accurate with them to boot!! We really need to get a sticky going on here about 64'sw:h:w:h:w:h::rockOn::rockOn::rockOn:
