    I have a 10/22 with a Green mountain 20" fluted BBL. My gun will only reliably shoot Federal brand .22lr ammunition, and some varieties of federal better than others. The problem is mostly FTFs. The best luck i have had is the Federal Wal Mart hollowpoint bulkpacks (rarely fail). most other brands are not even worth the trouble of loading the mag. Anybody have similar problems? any ideas on what the problem is? i have a very experienced gunsmith in the family, so i am considering taking it to him, but he is usually very busy, so for now i just shoot what works.

    Are you shooting with the factory rotary 10 round magazine? Or are you using "banana mags"? The Green Mountain barrels feature tighter chambers for better accuracy. Even so, I haven't seen a bad barrel from them that produced FTFs.

    i have a green mountain 16.5 in on a 10 22. i have the same problem. they did have a run of barrels in 2009, where they put a little camphor around the mouth of the chamber. it resulted in the rim on the cartridge being slightly recessed, so the firing pin does not fully strike the rim. but it was mostly the heavy taper sporter barrel like mine. not sure if your barrel is one of the bad ones. GM will fix the problem. i still have to call them to send it back. also GM uses a bentz chamber, which is snug. so if you have a ftf and try to pull back on the bolt to eject, it won't eject a live round. i hope all this made sense. this has been discussed on some rimfire sites.

    Is the barrel new? I have installed several GM and Whistle pig barrels on 10/22's over the years,and almost all of them were machined so tight to the ID of the action and I had to take a little time with Emory cloth sanding them down enough to fit the action good.
    If you forced the barrel into the action,it might not be back far enough and the headspace is too much,so the firing pin isn't making enough contact on the case to set off the primer.

    Just a thought! I haven't had any problems out of the guns that I've installed aftermarket barrels on.

    Nice flame! Only 4 posts and you are off and running.

    I'm not the worlds biggest 10/22 fan, but with good triggers and barrels they turn into amazing shooters.

    hahahhaaaa!

    I'll stick to my crappy Ruger. I like a Marlin fine but the one 10-22 and the AMT 10-22 copy I have are the best grouping rim fires I've had so far. And I've had a couple rim fires throughout my short time shooting (somewhere around 36 years);)

    Now back to topic,,,, Have you looked at how the round is seating to see if it's not in the right place? When you infered other ammo where these other bulk packs or some higher end target loads? I have horrible rtesults with most bulk ammo except the Federal bulk stuff. I might see one or two a box. And for the money they run me I really don't care. Higher end ammo is never a problem You're going to run into some duds in bulk stuff more often.
    You look at the rim to see if the pin is getting a good strike all the time?

    Sorry for so many questions. It's pretty hard to say what's up without seeing the rifle but most the time it's in the questions already asked or these. I had heard about some not so good GM barrels a while back. But that had been a good while back. If it's a new purchase I'm not too sure that6 would be the issue. But it's worth looking into.

    Thanks for the replies (most of them). I will take take a look at how the round is seating. I have tried quite a few different types of .22lr, both bulk and higher end stuff. I have tried a few different CCI varieties (standard V, Mini-Mags), Wolf Match, and they shoot no better than Remington golden bullet bulk packs.

    To guncrazy: i probably will eventually own a Model 60, because i am a gun fan in general. Everyone on here argues over which platforms are best, i just like to have them all covered :D There are some threads on here that are started with the question which do you prefer, this is not one. I was asking for help with something i own, which you offered none of.:rolleyes:

    I took the barrel off and inspected the chamber, then compared to some pictures i found of this chamfer problem from rimfire central. It appears this is the problem i have. I am going to contact green mountain about repair/replacement.

    Hope they can help correct your problem:D I have one of those crappy 1022 Rugers that I use for squirrels. Head shots at 60 + yds. Very accurate and never misses a lick. :p

    With mine I'm best with the Federal bulk but 22's being what they are they always like one ammo better than others. I say it all the time when someone gets a new 22. Look at a bunch of ammo and see what works best. It's prett funn really. I xcan group better with that 15 buck a box bulk than I can with match ammo.

    Let us know what you find out You having this problem might help someone else later.;) Have you taken any of the rounds that didn't fire and turn them to where a it can be struck elsewhere on the rim?

    I emailed Green Mountain about my problem. They are going to send me a shipping label so i can send them the barrel, and they will inspect it free of charge for manufacturing defects. If it is found to be a manufacturing defect (which it apparently is), they say they will repair or replace as necessary. Great customer service, pending they come through on what they say
