I've developed a jamming problem in both of my 10/22's at the same time. It's probably something I've caused myself. Two different 10/22's, 1st has about 4,000 round count, the other has about 10,000 rounds through it. What is happening is that it will extract the round, but not eject it fully before the bolt comes back and starts to feed the next round into the chamber. When it jams, the open mouth of the spent brass is always facing the bolt and the rim is facing the chamber. A live round will be half way into the chamber. Modifications to both rifles are the same - Power custom hammer w/ orig. Ruger hammer spring
Radiused tail of bolt stoned & polished hammer& sear Modified orig. Ruger bolt release cut one coil off trigger return spring replaced bolt stop pin with nylon pin 4 different magazines, clean inside, I have experimented with different winding tensions - no change. Any ideas what I screwed up? Hard to believe the extractor is the culprit. Problem did not happen till I made the above changes. Apologies for the crappy 5 year old flip phone photos. Thanks    Got the new extractors and installed them. I've only been able to put 50 rounds apiece through each 10/22's. So far, so good. The one extractor on the older 10/22 was pretty worn. It will be next week sometime before I get time to run through a couple hundred rounds to be sure of reliability.

The mods you list have no effect on extraction or ejection. Usually the symptom you describe is due to the extractor. If the fired case isn't held in position in the bolt face pocket, it will miss the ejector and fail to be kicked out to the side. Your OEM extractors could be dull, or their slots could be so dirty that they aren't closing all the way. Here's an article and vid about removing the cleaning the extractor: https://www.youtube.com/watch?v=vwKt1bCarYs
Also look at this article and check the condition of your extractors -although with such a low round count, they should be fine: https://1022companion.wordpress.com/2015/02/20/extractors/ If yours is dull, either the Volquartsen or the Kidd will be a giant improvement. If your extractor is functioning ok, another possibility is that you are allowing the rifle to move under recoil. In this case,the breech face of the barrel moves rearward and hits the extracted case before the case can be thrown clear. It's the rifle equivalent of limp-wristing a pistol, and I see it several times per year on Appleseed firing lines. It could also be that your bolt is short-stroking, so the fired case doesn't even hit the ejector. Your nylon bolt pin probably isn't the problem. But if you didn't put the hammer strut in properly, it could be impeding the hammer from cocking all the way and also stopping the bolt. Make sure the tip of the hammer strut is properly seated low in the hammer. When you cock the hammer manually, the movement should be smooth and consistent. Another possibility I've seen is that your ejector is not properly seated in its slot in the trigger housing. If it's flipped backward, it wreaks havoc with bolt travel causing short strokes. That's the full list of probable causes of the symptom you describe. |

Ruger bolt release cut one coil off trigger return spring replaced bolt stop pin with nylon pin (snip) Problem did not happen till I made the above changes. OK. The most common cause of the incomplete ejection, IMHO, is that the bolt is not moving to the rear with sufficient velocity to make the ejection happen with adequate energy. It is not uncommon for people to *very* slightly bend the guide rod while working on them (even if imperceptibly), and for that to cause more drag on the bolt. Modifying bolt release, etc., there are various options there for things to have gone wrong. You may want to verify that you have everything together correctly, and that nothing is dragging. While you have the bolt out, test the extractors - put a loaded round under the hook, shake the bolt around, the round should stay put. An easy test is to use hotter ammo (say, mini-mags, velocitors, stingers, etc.) and see if it makes the issue go away. If so, then the ability of the bolt to cycle sufficiently vigorously is likely the culprit. Give that a try, if the hotter ammo makes things start working better, then spend some time looking into why the bolt is undergoing a little more drag at some point. Commonly, people radius the bottom-rear edge of the bolt a bit to help it get started cocking the hammer, but since these started at the same time, I would first see if you could identify what's causing the extra drag. |

I can't believe you don't have a VQ edge extractor. That should be one of the first things everyone should put in their 10/22. I would try that before anything else I have the same problem. I just ordered the "VQ edge extractor" from RimfireSports.com for $11.95 with free shipping. That's a pretty cheap fix if it works. I love this place.

| Thanks for the replies. I checked both extractors, they both seemed to have a weak hold on the base on the case. Plus one charging handle rod seemed to be bowed ever so slightly when laid next to a straight edge ruler. So, I guess I'm ordering a couple of extractors & springs plus a new charging rod assem. Thanks again, I was sure I screwed something up. I did use different types of ammo to try to narrow it down though. CCI sv, Fed. auto-match, Blazer, Winchester hp, & Aguila hyper velocity. |

Didn't happen to leave the ejectors out or somehow install them incorrectly did you? A missing ejector would probably do what you're describing. |

If both rifles started malfunctioning at the same time, wouldn't the first thing that comes to mind be the ammo? Did you start using a new batch of ammo in your rifles?
If you rule out the ammo, and you performed all of those modifications at the exact same time, I would return one to stock configuration, then start adding the mods one by one to see what causes the malfunctions. |
| When this started, my first thought was the ammo or the fact I had torn down and cleaned my mags. But I never had a problem after cleaning my mags before. Even so, I took all 4 apart and re-assembled again just make sure I didn't have some kind of brain fart. So just for grins, I experimented with different tensions on the spring. Made sure mag rotors turned smoothly, no sticking or burrs. Didn't matter. I then tried a bunch of different types of ammo. Everything from CCI sv, mini-mags, Rem. thunderbolt, Fed. auto-match, Blazer, Winchester hp, Aguila rifle match & hyper velocity. FPS and bullet type didn't matter either. The last two mods I did at the same time on both rifles was to radius the tails of the bolts and modify the bolt releases. After I receive my 2 ejectors and charging handle, I'll see what happens. If they still jam, I'll work backwards, undoing my "improvements". At least my range is only 2 miles from the house and usually deserted except for me. Original extractors are correctly installed. |

+1 on the VQ extractor and hot enough ammo to get the bolt far enough back for the ejector to work . +1 again on the Volquartsen Exact Edge extractor. All my 10/22's have then. None of them were 100% reliable until I upgraded the extractor. Same with my MkII's |

I would try that before anything else SOUND ADVICE. i have a couple of them just sitting in my desk drawer and if any of my 10-22's start giving me extraction/ejection problems, the first thing I will do is install the VQ edge extractor. I will use the stock one until it starts to malfunction and then in goes the VQ edge one. Pretty simple to install too and use the spring that VQ sends with it. |
