on sunday i had a gun go boom instead of bang for the first time. i set some really stinky anchovies and waited for the mice to come, i had picked off 10 or so when one more ran up to the bait then BOOM!!!! my face was stinging and my ears hurt i could barely hear anything in my left ear it was ringing so bad. i had no idea what happened all i can remember is thinking "wow that was really loud for a 22..."

i looked down and saw smoke coming out of the action dinah turns to me and says "isn't the smoke supposed to come out of the other end" so i brushed off the little bits of brass that had peppered my face and ejected the shell... i'm lucky i didn't get any in my eyes.

the gun was an old cooey 600 that has shot thousands of rounds without doing this before and has shot a bunch since so i know it's not the gun
 
This has happened to me with more Remington thunderbolts than I care to remember. But it usually wasn't as catastrophic as that, just a small crack in the base of the cartridge. Always wear your glasses when shooting .22!!!

I have a scar between my eyes from the same thing and the same model and type of gun. With mine, the issue was the ejector failing and allowing a blowback from the round. There was blood everywhere and like I said I now have a scar. That gun got retired and is a den gun now. Your casing looks exactely like mine did after the incident.

lol i'll have to eat my words because the shells haven't ejected since then
 
Pardon the question, but what's with the crimped end - is it a rat-shot round, or something?

I have a Cooey 600, so keeping an eye on this thread, lest I lose the other .)
 
My Cooey 60 did the same thing one time with a Winchester Xpert round. Zero damage to the rifle. I found that there was a lot of crud built up right at the face of the breech which may have kept the round from seating in all the way, not sure if that caused it or not, but hasn't done it since. I also don't shoot Xpert any more.
 
X2, time to give the old girls a good cleaning, partially unsupported cases are notorious for cracking.

Looks like the same sort of rupture you get with a Dlask 10/22 and Blasers. I think the consensus on that is that the tighter chamber won't let the slightly oversized Blasers fully seat. Maybe drop one into an open chamber and see how far in it's seating? As others have said, could just need a cleaning.
 
i'd also check the chamber for a burr- that happened on my ithica 49 after a while- s*it gun to begin with-
 
Also, 22s will often shave off minute amounts of lead from the bullet on the sharp edge of the chamber, and this accumulates where the rim of the cartridge sits (the bolt slamming home then crushes this in. After awhile this will cause your round to sit <ever so slightly> behind where they should be.

It will give the same sort of symptoms as bad headspace (blown cases).

I've yet to experience a blown case, but I have seen such lead accumulation flake off when I scratch it with a needle in my own 22's.

Easy to miss since a regular chamber brush tends to not remove this.
 
Looks like the same thing that happened to me with a T.C. semi. Took it to the gunsmith who could find nothing wrong. The rifle never even had a box of shells through it at that time. It blew the mag. all to bits. When it happened to my son a short time later and T.C. would not answer my e-mails it went down the road.
 
This has happened to me loads and loads of times with Remington Thunderbolts or "Golden Bullets" biggest pieces of #### I've ever shot, like somebody else said eye protection on, and you're good to go.
 
:eek:
you aren't going to believe this...

(lets just say the guy who owned this before me was named bubba)

he effectively sharpened the extractors and ground the firing pin sharper too. he also marked up the bolt face

i'm lucky it hasn't happened before
 
The CCI stuff has the blue capsule thingy and comes in 12 round packs with a nifty plastic holder. The remington stuff is crimped and could easily be confused for a blank round/nail gun cartridge if you don't have the original box.

Never seen any of the Winchester stuff around here.

I believe cci is now selling that "mice shot" .22 stuff but it no longer has that crimped case......has a plastic see through dome holding the shot in.

Common mod for people trying to fix misfiring problems. Would be surprised if the "firing pin" was a ground up nail either.

I'd take that bolt appart at this point if I were you.
