interesting day at the range!

[FLIPNRR]

went to the range yesterday and to my suprise the rifle finally gave me its first major failure!...OOB!...just a short history ive been using federal bulk after the initial experimental ammo stage for a brand new rifle and never had problems with the feds and its always cleaned/lubed after every range session...had a few FTF on winchesters and cci before and round count on feds was 2,500 before this happened and it was a brand new box and it happened on the third mag...2 FTfire, 1 FTfeed and 1 OOB.

took apart the rifle and did an inspection and no issues visually and everything functions fine...cleaned/lubed then i went back to the range today for a follow up and bought a new box of feds and drove 40mins to academy sports just to get a box of blazers which was identical in reliability with the feds the results was good and had no issues with both boxes.

was this just a bad batch of ammo?

sorry to hear, sounds like it may have been the box.

i had my first ever gun issue yesterday at the range as well shooting federal bulk. FTF - ejected the round and looks like the tip was chipped up, missing about 3/4 of the material around the hollow point. no other issues in 200 rds total.

Sounds like a bad box to me as well. Haven't had a OOB on the 15-22 yet but on my other semi auto I had and it was the bullet that had a bad formed head.

Welcome to the 22LR ammo the best manufactured bullet on the planet made with care, perfect lead, just the right amount of powder and put together so carefully to make it work the best in the market.......... yea right... All joking aside, I use CCI Tactical and find that to work pretty much with zero issues.. good luck..

 

[rraisley]

I've only had one OOB, and it was using CCI Tactical ammo. Luckily, I felt the difference in the action, and did not fire. I ejected the round and put it back in the mag and tried again, and again, it would not go into battery. I saved the round, and found it would not drop in the chamber of any .22 I have (the 15-22 and 2 target pistols). I miced it and found it to be a little of .002 larger than the other rounds (the bullet, not the casing). I'm a bit surprised that small a change caused it, but I'm a bit more wary now.

 

[FLIPNRR]

already expected .22lr to be a non zero issue ammo but don't want to see the same problem as with the older version...as i read about it used to have more OOB's before the updated rifles.

There should be an acronym list haha..*** is oob? Nelp a noob

OOB stands for Out Of Battery. Not sure if it counts if the bolt/slide just does not go all the way to the proper location, or only if it fires OOB. Mine was OOB, but I felt it was different, so didn't fire. Most pistols won't fire OOB, but the 15-22 will (much to my surprise). BAD things can happen if the round goes off, but is not supported by the chamber.

I recently got a bad brick of federal, very very dirty, and a couple gouged up rounds. Usually it's pretty clean stuff for what it is.

I have to respectfully disagree, I had a misfire about a month ago, it went click but no boom. I look at the bolt area and it was a OOB. I ejected the round and looked at the primer area and there wasn't a strike. I think there must be a disconnect built in that will not let the pin strike the round unless the bolt is all the way forward. Which only seems right to be.

That's actually good to hear, but is not what I'd been led to believe here. I'd feel much better if it's true. And come to think of the design of the gun, if the bolt is not very far forward, the trigger will come up and hit the bottom of the bolt, but not the firing pin. Wonder at what point it would hit the firing pin?

When someone says OOB they usually mean Out Of Battery Discharge.

You'll know when you have one. Smith and Wesson MP 15-22 Bullet Misfire.mpg - YouTube

The casing will typically look something like this.

Phil, is the casing then almost always ruptured in an OOB discharge?

The ones I have personally seen and have seen pics of, yes. The casing fails due to not being supported by the chamber.

Phil,
The ones you have seen, was there anything else with the firearm? How old we're the firearms and were they all 15-22s?

Thanks,
Ryan

I had an OOB with my Ruger 22/45 after many years and tens of thousands of rounds.... just kept on shooting it. Most of the OOB with the 1522 had been in new rifles, but my 15-22 had an OOB after 20k rounds or so. Regularly cleaning the chamber is a good idea... but an OOB is typically a rare occurrence even in the most neglected .22s.

My only OOB was about a month ago with my new 15-22 (okay, maybe 1,000 rounds through it). It didn't actually fire off (would have, but I caught that it hadn't slammed the bolt home and looked before firing). It was caused by an oversize bullet in the CCI Tactical I was firing. I saved it, and miked it about 0.002 or so oversize, compared to the others. I tried the same round in 3 guns (the 15-22, obviously, and a Browning Medalist and High Standard Supermatic Trophy), and in every case, the round would not allow the slide/bolt to slam home. Now, in the pistols, it would not have fired OOB, because they won't allow it. But the 15-22 would have.

Anyhow, that's my only (close) OOB, and it was caused by defective (out of spec) ammo, not anything to do with the gun.
