    Ladies and gentlemen my father and I have a browning BuckMark that is 10 years old and has had no telling how many thousands of rounds ran through it. Unfortunatley it has developed a nasty habit of not ejecting a spent casing or not properly loading a new round, old casings are getting jammed in the slide and you cant shoot 10 rounds through it without at least 5 jams! I have cleaned the gun several times and lubed all the friction points with remoil and tried several types and brands of ammo. The gun is no longer enjoyable to plink with and is leaving a bad taste in my mouth with Brownings as the gun has always jammed to some degree. Has anyone had similiar experience with the BuckMark? Any suggestions?

    we have two mags...one that came with the gun and one that was purchased later. I have not purchased/tried new mags and do not know anyone who has one that i can borrow. I know that my old man did leave the mags loaded and sitting in the closet so perhaps the springs have just gotten weak? Do you think that a weak mag spring could effect ejection of spent casings? thanks!

    No, once the bullet loads successfully and fires, the magazine shouldn't be a factor. I doubt both magazines would go bad at exactly the same time, so I think you can eliminate that possibility. It was just an initial thought. Good luck...

    with no telling how many rounds feed through it ...

    I would suggest going to your local gunsmith have him polish the feed ramp...(feeding problem)
    and have him replace the spring in, if not the entire ejector .
    the spring in an older mag like that will ware out also if you leave them loaded ...youy may wanna check into new mags or atleast fresh springs for the mags you have .

    numrich is a good online place to look for hard to find parts

    Sounds like the ejector is not getting enough hook on the case. If there is a spring under the ejector replace it. Also new mag springs would be a good idea if they that old. I would not mess with feed ramp until you have the feeding and ejecting sorted out unless it is really rough.

    Try tightening all the screws as tight as they will go, even the grip screws, the gun will not function with any of them loose, This was always the first suggestion for any buckmark ftf issue, I have one about the same age, and have experienced the same thing. But not any more !! they are one of the most reliable 22 semi auto out there. The only other suggestion I have is CCI stingers do not shoot well at all, they are a hair longer and get tangled with the bottom of the ramp. Good luck

    DO NOT POLISH THE FEED RAMP!

    Do a detail strip of the entire gun, which is surprisingly easy. Here is a link to a Rimfire Central article on detail stripping the weapon: Dissecting a Buck Mark - RimfireCentral.com Forums

    Scrub and lubricate everything that could possibly move on the weapon. I would also suggest replacing any spring that you can.

    Re-assemble the gun, and make sure everything is nice and tight. Make sure all the screws are good and snug.

    I wouldn't look at the magazine if it's mangling cases and failing to eject. I'd wager it's more a problem with the extracter. Make sure it's very well cleaned and oiled.

    One more thing: You can't hate on a .22 for jamming. That's something damn near all of them do on occasion.

    +1 on what TheAutomator said. Have you ever tried to remove the barrel & reseat it again. I would try a good cleaning first.

    Need a breakdown drawing on the Buckmark?

    I have a Browning Buckmark I purchased new about twenty years ago and have never has any issues with it. You can go to Welcome to Numrich Gun Parts Corp. and they will probably have the replacement parts you need. I have a breakdown drawing in PDF format if anyone needs one. Just send me an email and I will attach and send back.

    A good cleaning can solve your problem, most of the time. I have problems after just a few rounds of cheap Remingtons. Seams that they have a small layer of some kind of wax coating on them. The wax builds up and can cause ejection and feeding problems. Also fine particles of dirt combined with to much oil will have the same result. I have fired many rounds of CCI and Federal ammo through mine without the slightest problem. As far as the stingers go, they are a little longer, but I have never had a problem with them, myself. I have also heard that some of the higher powered rounds burn the ejector rod over time. Which can cause it to bend slightly and cause feeding problems.

    My gunsmith and I just stripped the gun apart, after I faced similar problems. He said basically I just shoot too much... But seriously, the disconnector can actually wear down strangely. Browning Buck Mark Parts: MGW #5. My gunsmith said do a full spring replacement, firing pin included (even though it probably isn't necessary) before trying to order a new slide.

    You cleaned and lubed it?

    That's your problem right there ;) Last time I cleaned mine or bothered to run a boresnake through it was 7300 or more rounds ago :):

    Feed ramp, maybe. More than likely the extractor or spring has an issue. Wore out, brass shaving, something.

    Another thing to check, pinged chamber edge.
    Buckmarks are kinda soft, buddy got a 5.5 and pinged his up.
    Used a chamber iron and it ran fine (and he quit dry firing it ) ;)

    The extractor spring, plunger and the extractor itself need to be replaced.

    Secondly, check the edge of the chamber adjacent to the slot where the extractor sits when the slide is closed. If there is any damage, peening or the like, you might to clean that up. You can do it yourself if you know what you are doing.

    That and a good cleaning should help with the FTE issues.

    That being said, a 10 year old buckmark probably has a few other wear items you might need to replace. Specifically the recoil buffer pad, the firing pin spring and the ejector all come to mind. Maybe the disconnector spring too.
