stovepipe problems

I built my ten year old daughter a 10/22 using a Blackhawk Axiom stock. On it's maiden voyage to the range it was flawless except for a few duds which I blame on the Remington Thunderbolts (had the same issue in my Mark I). Since then I decided to do something about the crappy stock trigger and threw in a VQ hammer w/ the included springs and a PC titanium extractor. We took it to the range Saturday and about every fifth round was a stove pipe! All we ran through it was Winchester 333 as that was all I brought. What gives? The mags were stock Ruger and a BX25.

First off, clean the crud from the chamber and barrel that those Thunderbolts left behind. Then try some Federal Automatch or CCI-SV. Win 333's have given me problems like that from time to time. If that doesn't work, replace the stock parts and replace them one at a time with the aftermarket to see which upgrade is causing your problem. FYI, I used the stock springs with my VQ hammer and have had excellent results. :bthumb:
Every new 10-22 I work on and sell has a problem with poorly fit extractors and firing pins that are too short.

The extractor should cam out of the way of the cartridge case 0.015" when you slide the case under the extractor.

The firing pin should stand proud of the rim cut in the bolt by 0.025", 0.035" is better.

If you need help, send me a PM.

It's a new Power Custom titanium extractor in it. I got it on sale from Midway for like $8 so I bought it when I ordered some other stuff, I also dropped one in my MK I and it did fine. Maybe I'll try the stock extractor in it's place again.
I've bought the aftermarket extractors and all are just as bad as the OEM. It's not a problem with the extractor; it's the fit of the extractor to the bolt. Changing the extractor does nothing to the bolt tolerances and therefore no improvement in the function of the rifle.

The VQ has a hook 0.005" longer than the OEM extractor. Sometimes it's enough to correct the issue, many times not.

I've made this repair on hundreds of 10-22s and it works. ;)
extractor fitting

Keep hearing about fitting the extractor would love to see some pics and or drawings of what material needs to be removed where
thanks
Fitting the extractor to the bolt is easy. The extractor hook has to have enough pre-load on it to hold the cartridge case tight to the face of the bolt as it recoils until the base of the case hits the ejector and gets kicked out of the action. The case rim should push the extractor out of the way by 0.015" as it is slid up under the extractor. This gives the pre-load needed.

To get more pre-load you have to make the hook longer. The extractor is stopped in it's travel towards the cartridge case by it's machined slot in the bolt. To make the slot deeper would make the hook effectively longer, but man what a PITA. It's easier to modify the extractor.

If you look at the extractor you will note the hook at one end and the square lug at the other. Where you need to remove material from is the flat that is between the hook and lug. With the hook and lug facing up, I clamp the extractor in a small vise. I keep the area flat, but remove more material from the hook end. Take about 0.010" off and check the fit.

When you get the 0.015" cam out, break all corners to remove burrs or sharp edges and you're done.

I make it tapered, taking little off of the left end. What you show is the correct area.
Yes, that is how you remove the material. Not to get picky, but the red line should be below the original line of the extractor, but you have the idea down pat. In effect this makes the hook of the extractor longer. This in turn will make the extractor hold the spent case on the bolt face tighter. The width of the extractor is not critical.
I feel your pain

I have run into the issue, which I detail else where in the forum. I think three things are happening leading to the trouble. Each issue on its on wouldn't be enough to cause the trouble with the stovepipe jams, but all three at once, well you're going to have a long day.



My working theory...

1) the ammo. I love the Winchester 333 (22LR333HP), 'cause its cheap, but its also crap. It is, at times, underpowered and doesn't eject with enough force to clear the rifle, before the bolt slams shut, trapping the empty.

2) Its dirty. The Winchester 333 (22LR333HP) is a dirty bullet, and that dirt build up has an effect a number of things in the rifle. In this case, the build up of dirt is hindering the extraction hook, enough to cause trouble in the ejection process. Also I believe there is enough build-up in the chamber to slow the ejection of the spend casing. its working as friction layer between the brass and the chamber wall.

3) Its new. I believe that you'll have more trouble in the begin of the life cycle of the rifle than you will later. The new barrel is still tight and or rough enough to slow the ejection of the spent shell. The spring on the bolt is young and fresh making the bolt at its peak. While I see the magic break-in period for a new rifle to be about 200 rounds, I think it more like 2,000 rounds!

So when these three factors come together you get stovepipes. So how do you fix it?

1) Try a different (more) ammo. There's lots of stuff out there, you'll find one that works well for you.

2) Keep it clean. When my rifle starts with the stove pipes - I take a minute and pull my Bore Snake through it a couple time. At the end of my shooting day, I now clean up the rifle, focusing extra attention on the chamber, and extractor notch. I use to be pretty lazy about this, but no longer.

3) Shoot it more. That's the best part! I think the rifle needs a little more break-in time, and the best way to do that is go out and shoot it.

I've also order an "Exact Edge" extractor online, its under $20, you can't not get it for that price.

Opps I think I have the wrong definition of a stovepipe. The problem I'm having is live rounds getting caught going into the chamber. When you pull the bolt back and shake the gun ejector port pointed down the round will fall out (sometimes with the help of a finger) and the bullet will be bent. Again using stock mags.

In this case I would definitely try different ammo. Some guns just don't like the Win 333's. Break it in with some lead round nose ammo (Fed Automatch or CCI-SV) and then go back to the cheaper bulk stuff. Might need to clean the mags because the Thunderbolts you originally used is definitely dirtier than most. I have had similar problems when the crud builds up in the mag and doesn't allow the bullet to be pushed up high enough for the bolt to strip it.

When it jambs where is the bolt? Is it behind the cartridge case trying to push the round into the chamber, or is the bolt hitting the case in the mid-point, setting on top of the round?

The round is almost out of the clip at about a 50 deg angle with half the bullet in the chamber bent, the bolt is behind the round. I added one of those blocks that lock three mags together. They are new stock Ruger mags but I wonder if they are not seating completely due to a block/stock clearance issue. I had two guns to sight in Saturday so I did not pay too much attention to it. My dad was watching my daughter making sure she was safe, I just know I had to clear the action quite a bit. I figured I'd take it apart later. On it's first range trip it was flawless but I did not have the clip block either. I'll look at it closer tonight.

This would be the first thing I would look at. Try the rifle without the Tri-Mag set-up and see if you still have the problem. I see a lot of these at Appleseeds and most people that have them like them. Hopefully your problem is just that simple. :)
Interesting thread,I was thinking this morning if anyone had tried a stiffer plunger spring?
My issue is not gun related but magazine, the gun works with other mags, but not the 4 new ones. The gun had one week of league on it after being cleaned, about 120 rounds her magazines were dirty, I was going to clean them and she told me to just get her 4 new ones, and this is when the issues started, with the loaded round not feeding into the chamber. she is using the same ammo as last week, out of the same box so I would rule it out also.
