My Buckmark goes Kaboom!

Sound like the Browning held together better than a Glock would have......

Hardehardeharharhar! That's rich! Glock doesn't make peashooters; however, I'm pretty sure that they hold together pretty well, during a REAL KB.

Possible dirty chamber?

An over 30 year highmaster just told me he had this happened to him on a 22 ar15 due to dirty chamber. The round was so tight in the chamber due to carbon build up that when the bolt went to slam home after firing a round that it fired out of battery.

Except he's got the entire casing (minus the rim). And it was recoverd from fully seated in the barrel. That doesn't sound like an out of battery ingition. Look at the pic again.

Stinks about your pistol - glad you're alright . I hope Blazer makes things right for you.

From what I see and what he says about no ring or bulge in the barrel, I'd replace the parts and not worry about it. Although definitely worth trying to shame CCI into paying for repairs!

The aluminum top rail doesn't take a lot of force to bend, although I bet it held up a lot better than the plastic ones Browning has been using on the Camper models would have. The extractor seems to have blown off with the rim.

I quit buying Remington Golden bullet after getting way too many blown rims, although they only let loose over about 1/3 to 1/4 the circumference and caused no damage to my Ruger MK II or S&W M22A, but none of the blowouts ever aligned with the extractor. If they did I'd expect to need a new extractor.

I've had some bad lots of 22LR that bulged at the base in my autoloaders. I'm going to guess ammo problem.

I had a extractor and the other parts fly out of mine from wear. That probably somehow caused it to fire out of battery.

See that slot on the right side of the slide? That's where the case extractor should be. T'ain't there.

Do you have a normally fired 22lr empty case? It would be neat to see the problem case next to a normal case. Looking at the pictures again it looks like that case is extremely large, which may indicate a over loaded cartridge.

A fairly common cause of over pressure KaBooms! with normally loaded ammo is bullet setback -- particularly in .40S&W, but with .22lr the part of the bullet that is seated in the case is "rebated" or smaller in diameter that what is in front of the case making bullet setback nearly impossible.

Either CCI messed up with too much powder or too much priming compound (my bet because of the clean removal of the entire rim), or it was just a one in a gazillion defective case catastrophic failure.

If this is "fresh" production ammo, I wouldn't be surprised by a recall on this lot and its associated production runs.

That probably somehow caused it to fire out of battery.

Based on the photos of what remains of the case I'd bet a lot of money that it was fully into battery when fired.

You should visit this site to see some pictures of some pretty catastrophic Glock kaBOOMS. You'll see model 19s, 21s, 30s, 36s, etc.

A starting place: http://thegunzone.com/glock/greatest_hits.html

The link is in the “Glock Talk” section of the “Gun Zone”. Glock Talk has numerous kaBOOMS caused by numerous reasons (factory ammo, reloads, setbacks, etc.) to keep you busy for a while..

At my gun club we have a weekly Bullseye practice and most of us are using Buckmarks. One of the members had a similar though not quite so dramatic event with his Buckmark. The extractor and it's spring blew off the pistol when a cartridge head ruptured. He replaced the parts and continued using the pistol which by now at 100 rounds a week and a little over a year means 5000 more rounds has passed through the gun with no problem. I doubt there's enough power in a .22LR even with a bullet stuck in the barrel and another being fired into it to due much to the thick barrel of a Buckmark .22. I'd suspect there might have been a crack in the head of the .22 shell due to poor annealing before the case was formed or some such manufacturing error. If the barrel looks good, you can cycle .22 rounds manually through the gun and there's no slop in when you stick a .22 round in the chamber and try to wiggle it I wouldn't worry about it.
Glock kabooms are usually a function of a pentagonal barrel and using lead bullets. That type barrel tends to lead up. If you fire a bunch of lead bullets through it and then fire a jacketed bullet the chamber pressure can rise quite high due to lead fouling and a jacketed bullet being hard to push out of the barrel. Also some earlier Glocks had a pretty big cut out area just above the loading ramp that left part of the cartridge base unsupported. Lead and an unsupported cartridge base ain't good for holding things together.

I have a well maintained Nomad that has, on several occasions, fired with about one eighth inch of case not seated into the chamber. I believe the Buckmark & Nomad are essentially the same mechanism so I guess it's an ongoing problem. I usually "only" get pinged with blowback and no gun damage.

crazy! but at least it held up well

That is a case failure, probably the result of brittle brass being worked as the case head and rim were shaped. The head broke off before the case even had a chance to move back or to push the slide back. The escaping gas went up and only the wide open top kept the magazine from being blown out or the lips spread.

The pressure of a .22 LR is nothng to ignore; the SAAMI spec is 24,000 psi, more than many CF calibers.

(The above is in reference to the OP's report, not the case pictured in #40.)

Jim

The saving grace with a .22 even though the pressure is pretty high is that there's proportionally a lot more metal around a .22 cartridge in most guns than there is in most centerfires pistols.

Can you fathom how much you could make off those 8 bricks at a gun show right now? I literally just walked out of Gander Mountain where the total amount of .22lr was 150 rounds of bird shot. Been that way going on 3 weeks.

$110 estimated repair costs
5.5 bricks as compensation
valuation by CCI of $20/brick

how much does a brick go for today?
(not a .22LR firearm owner yet so honestly I don't know.)

Funny, my cousin just has a split case today using some Blazer ammunition. http://www.thehighroad.org/showthread.php?t=699050
Not funny "ha ha"... funny as in "how the heck did that happen!"

After 10's of thousands of 22 fired I have had 2 issues.

First was back in the mid 1980's. Using Remington Vipers in an older Remington 552. Had one fire out of battery. Nice little 22 caliber bottleneck case. Blew powder all over my face. I shoot left handed. Remington wanted old ammo back and I got shipped a new brick of same as replacement.


Second was with Remington bulk pack about 2 months ago. Misfires, jams bullets at an angle. I was using my Ruger MkII 10 inch stainless. One round fired out of battery. It was just a faint pop noise. I ejected the mag and smoke came out of my mag well and pistol for about 10 seconds. Barrel wasn't obstructed. Wife was standing right behind me and witnessed the whole thing. Who knows what happened. I contacted Remington with the info and never got a response. Guess they don't care about quality or customers anymore.

Hey If You...

Hey If You fired 15,000+ rounds in that Buckmark, I think she has proven herself to be worth a Browning once over. An intergrity check from the manufacturer is the only way that you will be totaly comfortable with her after that and 15k rounds makes her a worthwhile keeper. Don't cheat yourself out of a Browning Inspection, It'll be worth it.
