OOB is an Out of Battery discharge which basically means the round went off when it was not fully chambered.
 
OOB - out of battery
FTF - Failure to Feed OR Failure to Fire
FTE - Failure to Extract/Eject

Probably the most common three for a rimfire rifle. :)
 
Made it to 15k rounds +/- before having an OOB with the 15-22 today. I gave it a quick look over... looked fine... popped another 5rds... works fine. Will clean it up and go for another 15k rounds.

The OOB occurred during slow firing while sighting in new optic. Classic case of the round not fully chambering, bolt not closed yet the trigger still able to drop the hammer, engage the firing pin and ignite the round. :mad:

I hope everyone that has an OOB is sending an email to Smith. Heck, even if you have not experienced one yet.
If everyone got on them, maybe we would see a fix.
Of course they never answered my email, but with enough people showing concern, it might give them some incentive.

I sent S&W a nasty-gram back in January. No reply. My guess is that considering all the returns.... if they were going to make a design change they would have done so by now. For the firing mechanism to engage a 1/4''+ out of battery seems to me pretty poor design. None of my other 22s will do that. My S&W 22A trigger won't engage if there is a stiff breeze pushing against the bolt.
 
sorry to hear about your luck.. ive never had a 50 go oob but ive had several 30s and even a few casings break and then cook off.. allways good for video late in the afternoon... :D

flame pouring out of both ends of a belt fed gun is cool at almost dark:cool:
 
I thought I was lucky.... DTH didn't break. Though haven't really ispected it yet... that requires cleaning... :rolleyes.

Havn't seen you around much Beck.

By the way... your past advice about having a 'backup' rife worked out well. :D

Phil, I just now caught up on my reading here on the forum, and saw that you had an OOB. I hope nothing wasn't damaged. This is a good chance for me to learn something...IF you have not yet cleaned the rifle since the OOB, could you break the rifle down and see how easily or how hard a cartridge goes into the chamber? I'm real curious to see, of course the fly in the buttermilk is that maybe the OOB possibly cleaned the chamber. Anyway, it's worth a shot-no pun intended.

Quick off topic side road...I used to live in Tennessee and Chattanooga was the branch office, I was up in middle tenn, so I only got to the office when they made me come in. I'm curious as to whether you ever drove the "W road"? If you have then enough said, and is it still as bad as ever?

Hi used-to-be neighbor :D

The chamber looks fine as far as I can tell. Yes, with the rifle broken down a round will simply drop in and fall out when upside down. In fact, I can shake the upper and hear the round rattle in the chamber. The only thing I see is that there is a nick on the top edge of the bolt face (can be felt pretty good with a fingernail) and a faint scratch (not camera visible) right behind the nick going back abut an inch along the top of the bolt. I'm no gunsmith, but it does not appear to be an issue that would make much difference. Maybe it will even shoot better :rolleyes:

I ride my motorcycle up W now and then just for fun. And yes, it is as bad as ever even though they have tried to widen a couple curves.

dang phil if you would clean the carbon off the front of that bolt maybe it could close all the way...:D.. just playing glad to hear no real damage... and i think we are all getting together next sat for some plinking... if you wanna come play
 
Huh? That pic is after cleaning :o j/k

Thanks for the plinking offer I'm gonna have to make it up there one of these weekends. How about that shroud pic?
 
try and get that upp this weekend.. gotta work the next few..you gotta love long shifts
 
Thanks Phil. That eliminates my idea that these OOB's are caused by a possible "match" chamber that gets too dirty for a round to chamber. Another theory goes up in smoke. (My first experience with the "W" road was late one night in a dense fog, driving the pickup I had at the time...a full size F250 4wd, don't ask me how many times I backed up.)
 
Ran thru another 300+ rounds today with the 15-22 post OOB. No problems.... DTH = One tough rifle! :D

Do you feel like you are playing Russian Roulette since the OOB mishap?
If mine ever does the OOB thing, it will be on GB before the week is out.
I do love the rifle, but not that much. lol

Maybe the best way to answer that question is -- No more than before the OOB. :rolleyes:

Here's the way I see it. We all have a rifle that has a trigger that will drop the hammer and engage the firing pin with the bolt out of battery (Brett248Vista's video was a real eyebrow raiser.) Other than keeping the chamber clean and the bolt clean and operating smoothly I'm not sure what else 15-22 owners can do. I don't think I am any more likely to experience another OOB than I was the first one... or than anyone else is..... I suppose ??

Maybe the guy who is running S&W web sales department and sending out postcards to notify of out of stock items was in charge of the 15-22 firing mechanism design? :eek:
