Ruger 10/22 Scare

I tried searching around before posting, but couldn't find anything related to what happened to me yesterday (maybe I just don't know the proper term). Sorry if the post is a little long, I just wanted to include as much detail as I could.

I was at the range shooting pop cans with my Ruger yesterday. I had shot through twenty rounds of bulk pack Remington hollow points with no issue. I was two rounds into the third magazine, when all of the sudden there was a very loud bang that left me stunned with a ringing ear. I immediatley dropped the magazine, locked the bolt open, and walked away from the bench. Once I came to my senses and realized that I was not injured, I took a closer look at what happened. There was a crushed round partially loaded into the chamber, the extractor was laying on the table, and the magazine was covered in burnt powder.

I've shot close to 1500 rounds of the Remington bulk pack ammo through this rifle and have had no issues with cycling or feeding, and only have had a few duds (which I know is not unusual for bulk pack ammo).

The rifle was fairly clean. I shot about 200 rounds through her a few days before, and before that it was completely stripped and clean. I ran a boresnake through the barrel like I do before I begin any shooting session to ensure that there are no obstructions. Other than the extractor laying on the table, I did not see any signs of damage to the rifle when I took it apart - barrel, action, or otherwise. The crushed casing came out easily, I just picked it out with my fingernail.

The rifle itself has a Tactical Innovations 16.5", 1:16 twist bull barrel, a Tuffer Buffer bolt buffer, and I have done a trigger job to the factory parts. I have not changed any springs or done anything with the bolt other than installing the buffer. I've probably fired betwee 3000-4000 rounds through the rifle.

So I guess the question is what the hell caused this?

I was not shooting fast and the rifle was not hot. It was maybe 80 degrees out, but I only had shot 22 rounds through it at a normal rate of fire.

I'm certain that the first two shots hit the can because I got it to jump both times. I'm not sure if the third shot hit, but I don't believe there was an obstruction in the barrel, or at least not a full round. I am also certian that it did not fire as it was being loaded either because I had lined up the can in my scope and pulled the trigger.

It was almost as if the round did not load all the way into the chamber, but I was still able to fire it for some reason. I didn't think this was possible, but that is the only thing I can figure at this point.

Has anyone else had this happen to them, or have any other thoughts as to why this occured? I'll post some pictures when I get home tonight. Thanks!

improperly sized or formed brass?? is there enough left after the fact to even determine if the brass was within specs?

Sound like the gun jammed and the rim of the case got hit hard enough to fire the round with the bolt out of battery. My 10-22 does not like the Rem. Or Win. bulk pack HPs. I use Fed. classic bulk packs because they have a more round nose profile and feed better in my rifle.

I gave up completely on Rem bulk-pack ammo.

The last I bought would not even work in two old Winchester pumps.

About 1/4 of the rims were so far out of round they wouldn't go through the mag tube holes in the receivers.

I ended up shooting it up in a Colt Woodsman and a S&W revolver just to get rid of it.

Anyway, if your rims were as out of spec as my rims, I would not doubt a bit that one got hung in the Rugers magazine and the bolt set it off when it slammed into the edge of the rim.

I don't think the bolt slamming into the rim was the cause because I lined up my shot and pulled the trigger.

I was talking to a coworker about it and he brought up an interesting idea. His theory is that the metal casing was defective. When I pulled the trigger the brass failed and blew some of the gasses out the back causing the bolt to short cycle. The extractor blew off in the process leaving the shell partially in the chamber, and that the mushroom effect was from the bolt slamming back into the shell.

One idea I guess... I wonder if I can return/exchange the un-opened bulk pack I bought before I went to the range. And here I was happy with the Remington stuff because it had fewer jams and duds than the other brands I've tried.

I have had the same thing happen with a 10-22 . Not sure what brand of ammo. the case ruptured, and blew my extractor and spring who knows where. no big deal, except this is why eye protection should always be worn. I dont believe it was the rifle to blame, couple of bucks for a new extractor and spring from Ruger, and I was back in business. Just got to be aware that sometimes things happen. Good luck.

I was at the range when a 22 case blew out on a friend's 10/22 and it didn't cause anywhere near that kind of damage. It was a little noisier than most and he said he felt some gas on his face, but there was no damage to the gun. The case seperated right at the circumference of the rim. The damage to the case you described almost has to be an out-of-battery condition.

I had a case failure with some old .22LR ammo. Not as violent as yours, but some of the gas vented into the action. Left the case body as a sleeve in the chamber, and the base/rim as a little "lid" torn clean away.

Cartridge being set off before it was full chambered would be my guess for your incident.

If I were a betting man, this is where I'd place my bet. I quit buying the Remington Bulk Pack years ago precisely because I was getting way too many of these blown cases in my .22 pistols.

Yeah, I've heard of this before. IIRC its a design issue with the 10/22 in that it can fire out of battery like that. Search for ruger 10 22 magazine explosion.

Here is another example. (http://http://www.rugerforum.com/phpBB/viewtopic.php?t=78240&sid=bc9155ff6ba4700d20e9b48bbefd46cf)

and a really good writeup on the exact issue here (http://www.northeastshooters.com/vbulletin/threads/94360-Interesting-article-I-read-in-Gun-Tests-regarding-out-of-battery-firing-in-22-LR-s)

I had that happen to me with my wife's P22. The slide failed to return to battery completely and shot fire out of the ejection port. I was shooting remington bulk. Has never happened with CCI or Blazer. Blazer is now my new bulk ammo at 500@$19.99...... Well that is after I shoot up all my Fed bulk :D.

After a closer look at the case last night, I founds some burn holes in the side near the rim.

You know this maybe a little bit crazy but as much brass mushroom there it kinda looks like to me the bolt closed only to let the extracter rest on the head of the rim probably from the deformation of the rim of the shell. The firing pin is still long enough to strike the rim at this point and yes a rugger will fire without the bolt copletely closed. The head space now left between the shell casing and bolt is were the brass mushroomed and ruptured. The brass when fired with the hot gasses inside just like any cartridge is swelled and takes the form of its chamber, in this case part of it had no chamber. Thats my hypothises of youp pickures.

Also the bolt resting with the extracter atop the cartridge. May or may not be do to an out of round cartridge rim. Maybey a week bolt spring or the combination of both. I would definatly look at replacing your spring and a different ammo.( im a federal fan) shoot them in my ruger mark 2 pistol with no problems.

My grandson got a 10/22 last fall and we had several jams with it. The shell was not chambered and the bolt had bent the case and in one instance had hit the rim hard enough to bend it over at an angle. Did not go off but after seeing the damage to the rim I was surprised it hadn't.

Make sure to check the 2 allen head screws that hold the barrel, v block, to the receiver they may have worked loose and bound the extractor in the groove, not letting the bolt go fully forward , and firing out of battery.

Over tightening those screws can deform the v block as the stock ones are made of aluminum, but I think the threads would most likley strip out of the receiver first. There are aftermarket steel v blocks availble.

I had a similar experience with a Remington 597. Round was apparently not fully chambered and bolt was not in battery but fired. Blew the magazine out of the rifle and sort of scard the BJees out of me. Forget what ammo I was using at that time.

Thanks everyone! The VQ replacement extractor and spring should be showing up either today or tomorrow. Everything else appears to be intact.

I know a few have mentioned it, but this is a prime example of why eye protection should always be worn. I always wear Z87.1 glasses when shooting, but I do get a little lazy with ear protection with my .22 while on the range, not anymore!

Red-Demon652: You idea about what happened lines up with what I originally thought, I didn't know it could fire without the bolt being completely closed. The bolt spring seems to be in good shape, but I'm done with Remington bulk pack ammo.

Daggar Dog: The v block screws were still snug when I disassembled the rifle. I used a torque wrench when installing the barrel, if memory serves me right, I believe the specs are 20-25 in/lbs for the v block.
