View Full Version : Ruger 10/22 mis-fires?

I read in a recent post that a member had experienced many mis-fires with his 10/22, meaning firing pin indent in rim but no detonation of primer, using various brands of ammo. He decided to slightly file the face of his firing pin a little narrower to concentrate the impact force. He reports he has had reliable detonation since. Odd thing, I'm having the same problem with my 10/22. How many of you guys are having this problem with your ruger 10/22?

Never, sorry.
If you don't feel like stripping the bolt down to clean it, might shoot some carb or brake cleaner back along the firing pin to flush out any crud. I'm sure that's occurred to you, but might be a good tip for other users.
That might be a quick and easy way to see if the problem lies with simple fouling.....
Mainspring could be getting weak, although on an unmodified Ruger that's probably a long shot. They're pretty stout from the factory.
Slide the firing pin back and forth, see if there is any resistance, burrs, etc..... just a few thoughts.
Also might measure how far it protrudes past the boltface to see if it's a bit short....

Mike....cleaning and parts function not the cause, already checked that out. Also, the rifle is near new and weak springs couldn't be a factor. I thought it curious that two rifles had the same problem and wonderd if others were seeing it. If I get no bad reports from the members, I will think it's a fluke in this rifle and will take a good, hard look at it.

Have had several 10/22s, but never experienced any problems such as you describe. Soounds like thorough cleaning is in order.
Sorry

i have a AMT lightning pistol (ruger MKII clone) that does that. i'll try the file thing. i was getting ready to order a ruger firing pin and a set of wolff gunsprings for it, but i'm gonna wait and see if narrowing the firing pin tip is gonna do it. i'll let ya know.

I'm like MikeG, I use a few cleaners that were not originaly meant for guns and they work very well. He mentioned carb cleaner which will remove just about any crud. For you folks who may not know, be aware that some carb cleaners will dissolve paint, plastics and stock finish. In other words, make sure you know what you are spraying it on.
Sorry bowtek, don't have any 10-22 help for ya. Mine starts to jam when it gets pretty nasty but has never failed to fire a chambered round.
If you don't resolve your problem on the forum, I'll run the question by my local gunsmith. He's a friend of mine and as many guns as he works on, it's possible he has run into this before.

The feedback I'm getting so far is this is not a common problem with the 10/22 and maybe theres something in my rifle action causing it. Like a burr or a nick of some kind in the pin slot maybe.
MONTY...if you were about to spend the money for your amt upgrades to correct this problem, you can't lose anything by trying the pin face modification. You were gonna throw the old parts in the parts bin anyhow.....
LUMBERJACK...thanks...lets wait and see what other feedback we get here.

The only time I have had that happen is with a 500 box of Winchester gray box "target" ammo. That stuff was terrible and the misfires were definately the ammo, as it misfired in every .22 I tried it in. Regarding filing the firing pin down. Be careful. If you file it too much it can cause the rim of the case to split and you will get a lot of gas and crud blown back into the receiver. If the firing pin "dent" looks deep, it may be the ammo. If it looks shallow on the cases that misfire, the round might not be chambering all the way. Does the ammo fire if you try it a second time? If so, if a rifle has been dry fired a lot, a slight burr can be raised on the chamber that causes the round to not fully seat. The first blow seats the round all the way and sizes the case slightly, then it will rechamber the second time better and the second blow fires it. Check the condition of your chamber very closely to make sure dry firing has not raised a burr and to make sure the firing pin tip is not mushroomed.

BIG BORE.....I think your on to something here. I am seeing a shallow indent on the mis-fires.I do not dry fire a lot, especially rimfires, but your description of what happens when the shell is not fully seated is exactly what i'm seeing. I'll exam my chamber under my shop magnifying glass. Also, filing the pin would be my LAST resort. Something is causing this and it's most likey Not a defective part. The pin should work as is. Thanks for the lead....Bill

My 10/22 works fine with semi-good ammo, never had serious misfires unless it was crappy ammo. If you're going to file it why not just buy a new firing pin altogether?

that's my only gripe about the 10/22. no slide stop on the last round from the mag. i try to count the rounds as i shoot so i know not to pull the trigger after the chamber is empty, but when the gophers are out, i loose track and wind up trying to shoot eleven times. yep, pin dent on the chamber. sometimes i top off the mag when there's a lull in the action too, but i still sometimes do it.
bigbore: when i do the firing pin in my AMT, i'll not go smaller than the pin tip on my 10/22T. i've thought of this, and do not want a sharp point, just a smaller flat tip surface.
another thing on the ammo: some .22 ammo bullets will contact the rifling lead when chambered, and this may contribute to many misfires. my handgun has a different problem because i can see the where bolt face and barrel meet, and there is no gap after chambering a round.

Haven't experienced that.

HI Bowtek,
I had the same problem with my ruger model 96 in 22 mag. I sent the gun to a gunsmith . not sure what he did, but my gun came back working excellent. No more misfires. Ruger paid the gunsmith and I paid the shipping. Ruger will pay to fix it. go to your local gun dealer and ask.

We have seen that on occasion....I believe it has to do with three things...stacked tolerances....a rough feed ramp...and magazine problems.
I can send you instructions on how to disassemble and reassemble the magazine....
to address stacked tolerances...switch parts between guns or do some machining...
I have had one that has a feed ramp so rough that is slowed the round just enough to mess up the timing....I cleaned it up and the problem resolved it self...
i didn't really have a problem with misfires but i sent my bolt to RANDY AT CPC to get it worked on anyhow........ he trues up the bolt face and pins the fireing pin down and slicks up the back of the bolt then jewels it all for $55... like i said i didn't have issues but i wanted the custom work done anyhow..... might consider that........
