my ruger mark 1 jams all the time. it didnt used to do this. ive been using cci blazer ammo and it fails to eject almost every time. the empty comes out of the chamber and the live one gets started into the chamber but the empty gets stuck behind the live one and jams it. some other brands of ammo dont jam as much but its getting annoying. ive replaced the extractor with a brand new one and that hasnt helped at all.

does anyone know if blazer ammo is just weaker than others and doesnt kick enough to eject propperly? any tips on how i can get this gun working again?
 
Just a wild guess but I suspect it needs cleaned, Ruger mark models are diffcult to strip down but well worth the effort, I know I waited a long time before cleaning mine, I use FP10 and it functions flawless now,22 ammo is dirty.
 
I don'tknow about blazer .22 but I don't care for there other ammo.

Everytime I have had issues with my MKI jamming it has been caused by cleaning issues.

A gun can get real dirty in 20 years
 
thank you for the replys. definately not a cleaning issue. i know all the ins and outs of the dissassembly and i clean it very well before each range trip. it seems like the extractor just doesnt grip it very well. is it possible that the factory extractor is flawed?
 
Sounds like what my 22/45 was doing. After changing out the extractor,spring and plunger, the jamming was less frequent , but I still wasnt happy.I too thought I was cleaning my gun well, But I dont think I was getting the chamber clean enough, or the extractor well, next to the chamber. After changing brands of ammo, ( wally world bulk) and a very extensive barrel cleaning, I had no jams last time out shooting. I thought it was ammo related, untill my 8 year old son told me he was acually using the bulk ammo still. So, give it a good cleaning, I think that it was my issue all along.:)
 
First, try different ammo.

Then, since you have replaced the extractor..........

Pull the bolt out and take a tornado style brush and clean the chamber with bore cleaner. Then look closely at the ejector. Make sure it is not broken off. A stovepipe happens because the empty case is being forced loose from the extractor's grip before it ever gets to the ejector. Either the ejector is broken, or ...........
You might want to take a look at this page. MKII Stovepipes
 
Check to see if the ejector is loose or broken. I've a Mk II that stovepipes very frequently with Federal and rarely with Remington ammo. I swapped extractor spring and plunger between it and a 22/45 that had little trouble with either ammo, the problem did not switch guns. Then I saw the extractor was loose. I tightened it up with some "Grollia glue" (expanding polyurathane adhesive) using a small spring clip to hold it. Not a 100% cure but the stovepipe frequency reduced greatly with the Federal ammo from a couple every 30 rounds to a couple per every 300 rounds. I try to shoot Remington bulk Pak in this gun instead of the Federal.

latest range trip

i modified one of my magazines as per the instructions on that website. i even tried shaving down the bottom of my magazine butt to lower the mag but i only got slightly better extractions. jams every other shot or third shot.

as i said before its definately not a cleaning problem. my other hobbies include vintage motorcycles. ive rebuilt enought carburetors to know what clean means and this gun is cleaner than a complete carb rebuild. has been every time ive taken it out.

ive ordered a titanium extractor. volquartzen(spelling?) brand. ill update again when it arrives and i get to try it out.

my ejector doesnt seem to be broken. is it possible to grind it a bit to make it throw the brass outward instead of inward? are my magazine springs too firm, like the new cartrige is pushing too hard against the brass and disengageing it from extractor before it can hit the ejector?

thanks for all the ideas so far. hopefully the new extractor will fix it.
 
I would buy a box of 50 rounds in as many different brands of ammo and see what this pistol likes. I am not a fan of Blazer. All of my MKIIs run fine on Federal bulk ammo. They choke and cough on the Remington bulk.

I wouldn't grind on the ejector just yet. Instead, compare it to the ejector on a new MKII to see if it is correct. I have altered the angle on 1911 ejectors with some success, but I have never monkeyed with a MKII ejector. I don't think the mag spring could be the problem, but I could be wrong there. I'm thinking weak ammo, or weak cases expanding against the chamber and slowing extraction, assuming the ejector is OK.
 
ive tried holding my hand against the bolt to keep it in place then hand cycling it after firing to check for sticking in the chamber. it doesnt seem to be sticking. biggest reason im putting this much effort into getting blazer to work is cause when i take people out shooting for their first time they buy ammo and i keep getting stuck with all the extra ammo. they always buy blazer.
 
Next time you've got the bolt out, check to see if the ejector wobbles. I think it needs to go back to Ruger if the ejector is loose.

definately a buncha wiggle. i hadnt noticed that before. anyone know what the slot size is supposed to be in the bolt? or the extractor width? im getting ready to pull my extractor out and do some measurements. check the slot for signs of wear and things too. thanks for the idea.


EDIT.
extractor thickness im getting is .061 and the slot in the bolt is .066
 
How'd you get the ejector out? Mine looks like its rivited. I've a MkII that stovepipes often with Federal. I noticed the ejector was very loose compared to the 22/45 that had no troubles with this ammo. Since swapping extractor, spring and plunger made no difference, I tightened the ejector with some expanding polyurathane glue (Grollia Glue) and got the stovepipe frequency down well past tollerable. Don't know how long this will hold up however.

,ok, proof positive that im dumb. i was thinking extractor for the last few posts. no, my ejector isnt lose at all. i dont know how to remove a ejector.
 
Chamber iron.

Dry firing will cause the rear edge of the chamber to welt up a little.
 
My Mark 11 Target was doing the same thing. A call to Ruger for a new extractor and spring plus a new recoil spring unit fixed the problem at least in my gun. Parts with shipping as I recall were maybe a bit over $10 last year.
 
my volquartzen extractor finally came in. its in the gun and ive tried to hand cycle it and its doing much better. sunday i get to actually try it out. wish me luck. and thanks again for all the help.
 
timuchin-the breechface will not "welt up" unless the firing pin stop is not in place, as per the owners manual, and dry firing will not hurt a correctly assembled gun.
 
problem completely fixed! the volquartzen extractor rocks! 200 rounds with no malfunctions at all using the blazer ammo i hated so much. i am very happy.
 
Where did you get the Volquartzen extractor? I'd like to give one a try in mine that doesn't like Federal Champion ammo. I've looked a Midway, Natchez, and Brownells with no luck.

Thanks, I just ordered one, It'll be intresting to see if it fixes my occasional stovepiping problem with Federal Champion in my MkII.
